Poem

A rabbit hopped through Neovim night,
Building an MCP server—what a sight!
With context, tools, and tests galore,
Now Claude edits buffers, explores, and more.
Safe toggles, smart commands, docs that gleam,
This codebase hops ahead—an IDE dream!

🧹 Nitpick comments (53)
bin/claude-code-mcp-server (3)

13-15: Consider adding path validation for robustness.

The dynamic path detection using debug.getinfo is clever, but the string manipulation could be fragile. Consider adding validation to ensure the computed plugin_dir exists and is accessible.

-- Add this plugin to the runtime path
local script_dir = debug.getinfo(1, "S").source:sub(2):match("(.*/)")
local plugin_dir = script_dir .. "/.."
+
+-- Validate plugin directory exists
+local stat = vim.loop.fs_stat(plugin_dir)
+if not stat or stat.type ~= 'directory' then
+    vim.notify("Plugin directory not found: " .. plugin_dir, vim.log.levels.ERROR)
+    vim.cmd('quit! 1')
+    return
+end
+
vim.opt.runtimepath:prepend(plugin_dir)

57-63: Socket connection feature is appropriately marked as TODO.

The socket connection functionality is incomplete but properly documented as a TODO. This aligns with the WIP status of the PR. Consider implementing basic validation for the socket path when this feature is developed.

Would you like me to help implement the socket connection functionality or create an issue to track this feature?


25-32: Consider input validation for command line arguments.

The argument parsing works but lacks validation. Consider adding checks for edge cases like empty socket paths or malformed arguments.

-- Parse arguments
for i = 1, #args do
    if args[i] == "--socket" and args[i + 1] then
        socket_path = args[i + 1]
+        -- Validate socket path is not empty
+        if socket_path == "" then
+            vim.notify("Socket path cannot be empty", vim.log.levels.ERROR)
+            vim.cmd('quit! 1')
+            return
+        end
    elseif args[i] == "--help" or args[i] == "-h" then
        help = true
    end
end
test_mcp.sh (2)

5-5: Consider making server path configurable.

The hardcoded server path might not work in all environments.

-SERVER="./bin/claude-code-mcp-server"
+SERVER="${CLAUDE_MCP_SERVER:-./bin/claude-code-mcp-server}"

This allows overriding the server path via environment variable.


21-21: Improve JSON parsing fallback.

The jq fallback could be more informative.

-) | $SERVER 2>/dev/null | tail -1 | jq '.result.tools[] | .name' 2>/dev/null || echo "jq not available - raw output needed"
+) | $SERVER 2>/dev/null | tail -1 | if command -v jq >/dev/null; then jq '.result.tools[] | .name'; else echo "jq not available - showing raw JSON:"; cat; fi
lua/claude-code/utils.lua (2)

74-82: Consider path validation.

The function should validate that paths are strings and handle edge cases.

 function M.find_executable(paths)
+  if type(paths) ~= 'table' then
+    return nil
+  end
   for _, path in ipairs(paths) do
+    if type(path) ~= 'string' then
+      goto continue
+    end
     local expanded = vim.fn.expand(path)
     if vim.fn.executable(expanded) == 1 then
       return expanded
     end
+    ::continue::
   end
   return nil
 end

94-99: Add error handling for directory creation.

The function should provide more detailed error information.

 function M.ensure_directory(path)
+  if type(path) ~= 'string' or path == '' then
+    return false
+  end
   if vim.fn.isdirectory(path) == 0 then
-    return vim.fn.mkdir(path, "p") == 1
+    local result = vim.fn.mkdir(path, "p")
+    if result ~= 1 then
+      M.notify("Failed to create directory: " .. path, vim.log.levels.ERROR)
+      return false
+    end
   end
   return true
 end
doc/TECHNICAL_RESOURCES.md (2)

1-167: Fix markdown formatting issues for better readability.

The documentation content is comprehensive and valuable, but there are numerous markdown formatting issues flagged by linting tools.

Key formatting improvements needed:

  1. Add blank lines around headings
  2. Format bare URLs properly using [text](url) syntax
  3. Add blank lines around lists
  4. Add trailing newline

Example fixes:

### Official Documentation
+
- **MCP Specification**: [MCP Specification](https://modelcontextprotocol.io/specification/2025-03-26)
- **MCP Main Site**: [Model Context Protocol](https://modelcontextprotocol.io)
- **MCP GitHub Organization**: [MCP GitHub](https://github.com/modelcontextprotocol)

+
### MCP SDK and Implementation
+
- **TypeScript SDK**: [TypeScript SDK](https://github.com/modelcontextprotocol/typescript-sdk)

This will improve readability and compliance with markdown standards.

64-65: Make tool count expectations configurable.

The hardcoded expectations for tool counts (>=8 tools, >=6 resources) may become outdated as the codebase evolves.

Consider making these thresholds configurable or dynamic:

+# Tool and resource count expectations
+MIN_TOOLS=${MIN_TOOLS:-8}
+MIN_RESOURCES=${MIN_RESOURCES:-6}
+
 $NVIM --headless --noplugin -u tests/minimal-init.lua \
-  -c "lua local tools = require('claude-code.mcp.tools'); local count = 0; for _ in pairs(tools) do count = count + 1 end; print('Tools found: ' .. count); assert(count >= 8, 'Expected at least 8 tools')" \
+  -c "lua local tools = require('claude-code.mcp.tools'); local count = 0; for _ in pairs(tools) do count = count + 1 end; print('Tools found: ' .. count); assert(count >= ${MIN_TOOLS}, 'Expected at least ${MIN_TOOLS} tools')" \
   -c "qa!"
tests/spec/utils_spec.lua (2)

54-58: Platform-dependent test may be fragile.

The test assumes /bin/sh or /usr/bin/sh exists, which may not be true on all systems (e.g., Windows, some minimal containers).

     it("should find executable files", function()
-      -- Test with a command that should exist
-      local found = utils.find_executable({"/bin/sh", "/usr/bin/sh"})
-      assert.is_string(found)
+      -- Test with a command that should exist on most systems
+      local candidates = {}
+      if vim.fn.has('win32') == 1 then
+        candidates = {"cmd.exe", "cmd"}
+      else
+        candidates = {"/bin/sh", "/usr/bin/sh", "sh"}
+      end
+      local found = utils.find_executable(candidates)
+      assert.is_string(found)
     end)

114-118: Assumption about headless mode may not hold.

The test assumes it's running in headless mode, but this may not always be true depending on the test environment.

     it("should detect headless mode correctly", function()
       local is_headless = utils.is_headless()
       assert.is_boolean(is_headless)
-      -- In test environment, we're likely in headless mode
-      assert.is_true(is_headless)
+      -- The result should be consistent with vim's internal state
+      local expected = (vim.fn.has('gui_running') == 0) and (vim.v.event == nil or vim.v.event.cmdline == nil)
+      -- Note: Just verify it returns a boolean, actual value depends on test runner
     end)
doc/IMPLEMENTATION_PLAN.md (1)

1-233: Fix markdown formatting violations to improve readability.

The implementation plan content is comprehensive and well-structured, but there are numerous markdown formatting issues that should be addressed for better consistency and readability.

Key formatting improvements needed:

  • Add blank lines around headings (MD022)
  • Add blank lines around lists (MD032)
  • Add blank lines around fenced code blocks (MD031)
  • Specify language for code blocks (MD040)
  • Remove trailing punctuation from headings (MD026)
  • Add final newline (MD047)

Apply these changes to improve formatting:

-### Option A: TypeScript/Node.js
+
+### Option A: TypeScript/Node.js
+
 **Pros:**
+
 - Can fork/improve mcp-neovim-server
 - MCP SDK available for TypeScript
 - Standard in MCP ecosystem
 - Faster initial development
+
 
 **Cons:**
+
 - Requires Node.js runtime
 - Not native to Neovim ecosystem
 - Extra dependency for users
+

102-102: Fix trailing spaces in YAML.

Multiple lines in this file have trailing spaces that violate YAML formatting standards.

Apply this diff to remove trailing spaces:

-      - name: Run unit tests
+      - name: Run unit tests

Note: Similar trailing space issues exist on lines 98, 101, 107, 112, 118, 129, 133, 136, 142, 145, 153, 163, 170, 171, and 177.


113-117: Improve timeout handling and error messaging.

The timeout handling is good, but the test could be more informative about failures.

Consider this improvement:

       - name: Test MCP server standalone
         run: |
-          # Test that MCP server can start without errors
-          timeout 5s ./bin/claude-code-mcp-server --help || test $? -eq 124
+          # Test that MCP server can start without errors
+          if ! timeout 5s ./bin/claude-code-mcp-server --help; then
+            exit_code=$?
+            if [ $exit_code -eq 124 ]; then
+              echo "✅ Server help command timed out as expected"
+            else
+              echo "❌ Server help command failed with exit code $exit_code"
+              exit 1
+            fi
+          else
+            echo "✅ Server help command succeeded"
+          fi

164-176: Validate tool count expectations.

The test expects "at least 8 tools" but this hardcoded number could become brittle as the codebase evolves.

Consider making the test more flexible:

-            -c "lua local tools = require('claude-code.mcp.tools'); local count = 0; for _ in pairs(tools) do count = count + 1 end; print('Tools found: ' .. count); assert(count >= 8, 'Expected at least 8 tools'); print('✅ Tools test passed')" \

287-307: Consider improving the multi-select UX pattern.

The recursive selection pattern for multiple servers could be enhanced for better user experience. The current implementation requires users to select one server at a time and then choose whether to add more.

Consider implementing a more standard multi-select interface using checkboxes or a dedicated multi-select UI component. This would allow users to select all desired servers at once rather than iteratively.

Would you like me to provide an implementation using a multi-select approach?


328-328: Address the TODO: Implement server installation logic.

  • Binary download and installation for native servers

lua/claude-code/init.lua (2)

31-37: Consider the implications of exposing internal modules.

Exposing internal modules (especially _config with underscore prefix suggesting private) on the public API surface could lead to:

  • Users depending on internal implementation details
  • Breaking changes being harder to manage
  • Confusion about which APIs are stable vs internal

Consider documenting which of these are public APIs vs internal implementation details, or provide a more controlled public API surface.


201-201: Consider making the startup notification configurable.

The "Claude Code plugin loaded" notification on every startup might be unnecessary for users. Consider making this configurable or using DEBUG level.

-  vim.notify("Claude Code plugin loaded", vim.log.levels.INFO)
+  if M.config.show_startup_message ~= false then
+    vim.notify("Claude Code plugin loaded", vim.log.levels.INFO)
+  end
lua/claude-code/mcp/server.lua (2)

71-71: Consider making the protocol version configurable.

The hardcoded protocol version "2024-11-05" should be documented or made configurable to ensure compatibility with different MCP protocol versions.

-        protocolVersion = "2024-11-05",
+        protocolVersion = server.protocol_version or "2024-11-05", -- Default to MCP protocol version

Also update the server initialization:

local server = {
    name = "claude-code-nvim",
    version = "1.0.0",
    protocol_version = "2024-11-05", -- MCP protocol version
    -- ... rest of the fields
}

240-241: Verify stdio availability before opening file descriptors.

Opening file descriptors 0 and 1 directly assumes they're available and not already in use. This might fail in non-headless Neovim instances.

Consider checking if running in headless mode:

-- Check if we're in a suitable environment
if not vim.fn.has('nvim-0.5') then
    notify("MCP server requires Neovim 0.5+", vim.log.levels.ERROR)
    return false
end

-- For non-headless instances, we might need different handling
if vim.fn.has('gui_running') == 1 or vim.g.neovide then
    notify("MCP server may not work correctly in GUI mode", vim.log.levels.WARN)
end

323-502: Excellent compilation of implementation questions.

This comprehensive list of open questions demonstrates thorough analysis and will be valuable for guiding the implementation. Many of these questions (especially around message framing, lifecycle management, and error handling) are directly relevant to improving the current server implementation.

Would you like me to help research answers to specific questions or create GitHub issues to track the investigation of these unknowns?

87-93: Consider using a Git library or validating the git executable path.

Using io.popen with external commands can be a security risk if the PATH is compromised.

Consider using a Lua Git library like lua-git or at minimum validate the git executable path:

-        local handle = io.popen("git status --porcelain 2>/dev/null")
+        local git_path = vim.fn.exepath("git")
+        if git_path == "" then
+            return "Git not available"
+        end
+        local handle = io.popen(git_path .. " status --porcelain 2>/dev/null")

163-163: Add error handling for JSON encoding.

JSON encoding can fail with certain data types.

Wrap the JSON encoding in a protected call:

-        return vim.json.encode(result)
+        local ok, json = pcall(vim.json.encode, result)
+        if not ok then
+            return '{"error": "Failed to encode diagnostics"}'
+        end
+        return json

6-6: Fix markdown formatting issues for better readability and standards compliance.

The static analysis identified several markdown formatting issues that should be addressed.

Apply these formatting fixes:

  1. Add blank lines around lists (lines 6, 26, 63, 117, 123, 129)
  2. Add language specifiers to code blocks (lines 17, 83)
  3. Add blank lines around fenced code blocks (lines 45, 69, 147, 157)
  4. Add blank lines around headings (lines 59, 80, 115, 122, 128, 146, 156)
  5. Add a trailing newline at the end of the file (line 188)

Example fixes:

 Current MCP integrations (like mcp-neovim-server → Claude Desktop) route code through cloud services, which is unacceptable for:
+
 - Enterprises with strict data sovereignty requirements
-```
+```text
 ┌─────────────┐     MCP      ┌──────────────────┐     Neovim RPC     ┌────────────┐
 By building an MCP server that prioritizes local execution and enterprise security, we can enable AI-assisted development for organizations that cannot use cloud-based solutions. This approach provides the benefits of Claude Code integration while maintaining complete control over sensitive codebases.

257-264: Add bounds validation for mark positions.

The function should validate line and column positions before setting marks.

Add validation:

         local bufnr = vim.api.nvim_get_current_buf()
+        local line_count = vim.api.nvim_buf_line_count(bufnr)
+        
+        if line < 1 or line > line_count then
+            return string.format("Error: line %d is out of bounds (1-%d)", line, line_count)
+        end
+        
         vim.api.nvim_buf_set_mark(bufnr, mark, line, column, {})

326-340: Add validation for visual selection bounds.

Invalid positions could cause errors when setting cursor positions.

Add bounds validation:

     handler = function(args)
         local start_line = args.startLine
         local start_col = args.startColumn
         local end_line = args.endLine

+        local bufnr = vim.api.nvim_get_current_buf()
+        local line_count = vim.api.nvim_buf_line_count(bufnr)
+        
+        if start_line < 1 or start_line > line_count or end_line < 1 or end_line > line_count then
+            return "Error: Line positions out of bounds"
+        end
+

7-11: Nit: Respect Markdown lint rules for blank lines
Several headings (e.g., lines 5, 13, 21) and list blocks (e.g., lines 9–11) lack surrounding blank lines, triggering MD022/MD032. Adding blank lines before/after headings and list items will improve readability and satisfy markdownlint.

Also applies to: 13-18, 21-52

doc/PLUGIN_INTEGRATION_PLAN.md (1)

167-191: Improve installation helper path resolution
Cloning from stdpath('config')..'/claude-code.nvim' assumes a directory layout that may vary. Consider using the plugin’s runtime path (via vim.api.nvim_get_runtime_file) or stdpath('data') to locate source files reliably.

doc/MCP_CODE_EXAMPLES.md (7)

6-38: Minimal server example is concise
The snippet clearly shows instantiation, Zod-validated tool registration, and stdio transport connection. For production readiness, you might wrap await server.connect(transport) in a try/catch to log connection errors.

74-144: Enhance handler error reporting and typing

  • Use a structured MCPError (instead of generic Error) to attach isError and errorCode for RPC failures.
  • Leverage the SDK’s generated schemas or Zod types rather than hand-rolled JSON literals to ensure schema consistency.
  • Narrow request.params.arguments from any to a typed interface for stronger type safety.

198-203: Consider localized error handling in run()
While the top-level .catch(console.error) works, wrapping await this.server.connect() inside run() with its own try/catch can provide more contextual error messages before exiting.


212-245: Neovim client API wrapper is robust
The NeovimClient abstraction neatly encapsulates connection, buffer listing, and line operations. For production, you may want to catch and rethrow RPC errors as MCPError to unify error handling.

311-324: Handle absence of LSP clients gracefully
luaeval("vim.diagnostic.get()") may throw if no LSP is active. Wrap this in a try/catch and return an empty diagnostics array or a structured warning to avoid server crashes.


328-334: Improve MCPError for JSON-RPC compatibility
Set this.name = 'MCPError' in the constructor to retain error identity, and consider adding a toJSON() method so JSON-RPC layers can serialize message and code cleanly.


397-411: Extend tests to cover error path
The Jest test verifies successful edits. Add a test where setBufferLine throws to ensure the server returns isError: true and the correct error message.

105-116: Quote example paths in Quick Start
In the snippet adding the MCP server (claude mcp add neovim-server /path/to/...), wrapping paths in quotes or using $HOME can prevent shell parsing issues.

🔇 Additional comments (51)
.vscode/settings.json (1)

1-11: LGTM! Well-structured development environment configuration.

The VSCode settings properly configure custom toolchain paths using workspace-relative directories, which ensures portability across development environments. The configuration supports both Go and Node.js development needs for the MCP server integration.

ROADMAP.md (1)

42-46: Excellent strategic addition to the roadmap.

The new "Inline Code Suggestions" section aligns perfectly with the MCP server integration being introduced. The specific mention of using the "fast Haiku model" shows thoughtful consideration of performance requirements for real-time features.

.claude/settings.local.json (1)

1-23: Well-configured permission model with appropriate security boundaries.

The permission configuration follows security best practices by:

  • Explicitly listing allowed operations rather than using broad permissions
  • Restricting web fetch to only the necessary domain (docs.anthropic.com)
  • Using specific command patterns for bash operations
  • Enabling MCP servers while maintaining controlled access

This provides a good balance between functionality and security for the MCP server integration.

Makefile (2)

1-41: Clean integration of MCP testing into the build system.

The Makefile updates properly support the test directory consolidation and add comprehensive MCP testing capabilities. The changes maintain backward compatibility while extending the test suite appropriately.


74-74: Good documentation of the new MCP test target.

The help output clearly documents the new make test-mcp command, making it discoverable for developers.

bin/claude-code-mcp-server (1)

65-72: Good error handling for server startup.

The script properly handles MCP server initialization errors with appropriate error messages and exit codes. The success checking ensures reliable startup behavior.

tests/README.md (2)

155-170: Well-documented legacy test structure.

The legacy tests section provides clear guidance on VimL-based backward compatibility testing with appropriate file descriptions and usage examples.


171-179: Comprehensive interactive test documentation.

The interactive tests section effectively documents the MCP testing utilities and available commands for manual testing.

test_mcp.sh (1)

1-2: Good shell script header.

Proper shebang and clear structure.

lua/claude-code/config.lua (1)

108-130: Well-structured MCP configuration.

The MCP configuration section provides comprehensive control over tools and resources with sensible defaults.

lua/claude-code/utils.lua (2)

8-34: Robust notification handling.

The notify function properly handles both UI and headless modes with appropriate fallbacks.


36-52: Useful color utilities.

The color system provides a clean interface for terminal output formatting.

lua/claude-code/terminal.lua (1)

186-191: Inconsistency between AI summary and actual implementation.

The AI summary mentions MCP server integration and automatic server startup, but the actual code changes only show command variant functionality without any MCP-specific logic.

Likely an incorrect or invalid review comment.

doc/TECHNICAL_RESOURCES.md (1)

1-167: Excellent comprehensive resource compilation.

This documentation provides valuable centralized resources for MCP and Neovim development, covering official docs, SDKs, examples, testing, security, and performance considerations.

22-180:

✅ Verification successful

Consider addressing markdown formatting issues.

The static analysis tools have identified numerous markdown formatting issues including:

  • Headings should be surrounded by blank lines
  • Trailing punctuation in headings
  • Lists should be surrounded by blank lines
  • Trailing spaces

While these don't affect functionality, addressing them would improve document consistency and readability.

Run the following script to auto-fix some markdown issues:


🏁 Script executed:

#!/bin/bash
# Install and run markdownlint with auto-fix
npm install -g markdownlint-cli
markdownlint --fix doc/IDE_INTEGRATION_OVERVIEW.md

Length of output: 1853


To work around the permission errors, let’s retry auto-fixing with npx (no global install required):


🏁 Script executed:

#!/bin/bash
# Auto-fix markdown lint issues via npx
npx markdownlint-cli@latest --fix doc/IDE_INTEGRATION_OVERVIEW.md

Length of output: 164


Let’s check for any remaining lint violations by listing (not fixing) issues:


🏁 Script executed:

#!/bin/bash
# List markdownlint violations without auto-fix
npx markdownlint-cli@latest doc/IDE_INTEGRATION_OVERVIEW.md

Length of output: 61


No Markdown formatting issues remain in doc/IDE_INTEGRATION_OVERVIEW.md

After running markdownlint-cli via npx (with --fix) and verifying, there are no remaining lint violations. The document is now consistently formatted.

lua/claude-code/init.lua (1)

52-68: Good improvement to buffer detection logic.

The new implementation is more robust as it:

  • Doesn't rely on internal state tracking
  • Can find Claude Code terminals even if the plugin's state is inconsistent
  • Uses a clear pattern match for identification
lua/claude-code/mcp/server.lua (2)

6-9: Good use of stderr for server notifications.

The force_stderr = true option is appropriate here since stdout is reserved for JSON-RPC communication with the MCP client.


265-285:

❌ Incorrect review comment

Critical: Implement proper JSON-RPC message framing with Content-Length headers.

The current implementation uses newline-delimited JSON, but standard MCP/JSON-RPC clients use Content-Length headers for message framing (similar to LSP). This will cause compatibility issues with MCP clients.

Consider implementing proper message framing:

-- Example of Content-Length parsing
local headers = {}
local content_length = 0

-- Parse headers
while true do
    local line = -- read until \r\n
    if line == "" then break end
    local key, value = line:match("^([^:]+):%s*(.+)$")
    if key == "Content-Length" then
        content_length = tonumber(value)
    end
end

-- Read body based on Content-Length
local body = -- read exactly content_length bytes

🌐 Web query:

What is the standard message framing format for MCP servers - Content-Length headers or newline-delimited JSON?

💡 Result:

The Model Context Protocol (MCP) utilizes JSON-RPC 2.0 for message formatting, ensuring a standardized structure for communication between clients and servers. Regarding message framing, MCP defines two primary transport mechanisms:

  1. Standard Input/Output (stdio): In this setup, the client launches the MCP server as a subprocess. The server receives JSON-RPC messages via standard input (stdin) and writes responses to standard output (stdout). Messages are newline-delimited and must not contain embedded newlines. This approach is particularly useful for local integrations and command-line tools. (spec.modelcontextprotocol.io)

  2. HTTP with Server-Sent Events (SSE): Here, the server operates as an independent process capable of handling multiple client connections. The server provides two endpoints:

    • SSE Endpoint: Clients establish connections to receive messages from the server.
    • HTTP POST Endpoint: Clients send messages to the server using HTTP POST requests.

    In this mechanism, server messages are sent as SSE message events, with the message content JSON-encoded in the event data. (spec.modelcontextprotocol.io)

Both transport mechanisms rely on JSON-RPC 2.0 for message formatting, but they differ in how messages are transmitted and framed. The stdio transport uses newline-delimited JSON messages, while the HTTP with SSE transport employs JSON-encoded data within SSE events.

Citations:


Incorrect framing concern: newline-delimited JSON is the MCP stdio transport standard

According to the MCP spec, the stdio transport uses newline-delimited JSON messages (no Content-Length headers), while the HTTP/SSE transport uses SSE events. Your current implementation in lua/claude-code/mcp/server.lua correctly follows the stdio framing and requires no changes.

Likely an incorrect or invalid review comment.

doc/PURE_LUA_MCP_ANALYSIS.md (1)

101-103: Good acknowledgment of JSON-RPC parsing requirements.

The comment correctly identifies that proper JSON-RPC parsing with Content-Length headers is needed for a production implementation. Consider adding a reference to the LSP specification's base protocol section which documents this format.

doc/IDE_INTEGRATION_DETAIL.md (1)

34-38: Clear documentation of stdio as the standard MCP server transport.

Good clarification that stdio is the standard transport for MCP servers, which aligns with the implementation.

lua/claude-code/mcp/resources.lua (1)

13-13: 🛠️ Refactor suggestion

Replace deprecated nvim_buf_get_option with nvim_get_option_value.

The nvim_buf_get_option API is deprecated in recent Neovim versions.

Apply this diff to use the newer API:

-        local filetype = vim.api.nvim_buf_get_option(bufnr, "filetype")
+        local filetype = vim.api.nvim_get_option_value("filetype", { buf = bufnr })

Likely an incorrect or invalid review comment.

lua/claude-code/mcp/tools.lua (1)

206-231: Well-designed window management with proper security constraints.

The implementation correctly limits allowed commands to a safe subset and includes proper error handling.

doc/POTENTIAL_INTEGRATIONS.md (1)

1-117: Well-structured vision for IDE-like MCP integrations
The document presents a comprehensive, phased roadmap of MCP tools and capabilities inspired by Cursor and VS Code, Complete with technical considerations. It clearly communicates objectives and aligns with the overall plugin strategy.

doc/MCP_CODE_EXAMPLES.md (2)

44-69: Core NeovimMCPServer setup is correct
Imports and constructor usage follow the SDK’s patterns. The separation of server initialization and handler setup makes the code modular and easy to extend.


146-170: handleEditBuffer correctly handles success and errors
The line offset adjustment and inclusion of isError: true on failures are handled well. Nice work!

README.md (4)

17-25: Integrated “MCP Server” into TOC and Features
The new table of contents entry (line 17) and the “MCP Server (NEW!)” feature list (lines 39–48) clearly differentiate the native server capabilities.


57-63: Clarify CLI detection and overrides
You describe preferring ~/.claude/local/claude over claude in PATH. Consider documenting environment variable or configuration overrides (e.g., command = "/custom/path/claude") so users know how to adjust that behavior.


137-147: Verify tools list matches implementation
Ensure the listed tool identifiers (e.g., vim_edit, vim_window) match exactly the names registered in lua/claude-code/mcp/tools.lua. Discrepancies will cause missing tool errors.


149-158: Confirm resource URIs align with code
Check that URIs like neovim://current-buffer and neovim://project correspond to those produced by your resource handlers in resources.lua. Mismatches here will break resource enumeration.

- Simplify MCP Hub to use mcp-neovim-server directly
  - Remove complex plugin path detection logic
  - Update default server to use globally installed mcp-neovim-server
  - Change from "native" to "official" server designation

- Update documentation and tests
  - Update README standalone examples to use mcp-neovim-server directly
  - Update test script to check for global mcp-neovim-server installation
  - Remove obsolete bin_mcp_server_validation_spec.lua test

This follows standard Neovim plugin patterns where users interact through
vim commands rather than external scripts in PATH. Users now simply:
1. Install plugin via plugin manager
2. Install mcp-neovim-server via npm (if desired)
3. Use plugin's built-in commands

- Fix variable name error in test_mcp_configurable_spec.lua (default_path → default_cmd)
- Update test_mcp.sh to use new module paths:
  - claude-code.mcp.tools → claude-code.mcp_tools
  - claude-code.mcp.resources → claude-code.mcp_resources
  - claude-code.mcp.hub → claude-code.mcp_hub
- Update test validation to check for mcp-neovim-server command availability
  instead of old SERVER= pattern

This fixes the CI test failure caused by the bin/ directory removal and
MCP architecture changes.

I just wanted to say thank you for this (and @greggh too of course!), :ClaudeCodeWithFile and :ClaudeCodeWithSelection will be gamechangers.

life threw curveballs.
i don't have the time at the moment and honestly if i did, i also don't have the motivation to continue working on this at the moment.

if someone wants to pick up where i left off, that might be the best way to get this moving forward
