Baseline MCP Server

English Version | 日本語版

A Model Context Protocol server that provides Web Platform API support status.

Overview

This server implements an MCP server that can retrieve Baseline status (support status) of Web API features using the Web Platform Dashboard API. It fetches information about web features based on queries and returns the results to MCP clients.

Features

• Feature search using Web Platform Dashboard API
• Providing Baseline status (widely, newly, limited, no_data) for features
• Browser implementation status (version and release date)
• Feature usage data
• Feature search excluding specific browsers (chrome, edge, firefox, safari)
• Integration with various AI models via MCP

About Baseline Status

Baseline status indicates browser support for web features:

• widely: Widely supported web standard features. Safe to use in most browsers.
• newly: Newly standardized web features. Beginning to be supported in major browsers but still in the process of adoption.
• limited: Web features with limited support. May not be available in some browsers or may require flags.
• no_data: Web features not currently included in Baseline. Browser support status needs to be checked individually.

For more details about Baseline, refer to "Baseline (Compatibility) - MDN Web Docs Glossary".

MCP Client Configuration

• Deno is recommended for running the server
  • Please only allow access to api.webstatus.dev as a permission
• Specify @yamanoku/baseline-mcp-server or set up your local environment to read baseline-mcp-server.ts

Claude Desktop

To use with Claude Desktop's MCP client, add the following configuration to cline_mcp_settings.json:

{
  "mcpServers": {
    "baseline-mcp-server": {
      "command": "deno",
      "args": [
        "run",
        "--allow-net=api.webstatus.dev",
        "jsr:@yamanoku/baseline-mcp-server"
      ]
    }
  }
}

Visual Studio Code

To use with Visual Studio Code's MCP client, add the following configuration to settings.json:

{
  "mcp": {
    "servers": {
      "baseline-mcp-server": {
        "command": "deno",
        "args": [
          "run",
          "--allow-net=api.webstatus.dev",
          "jsr:@yamanoku/baseline-mcp-server"
        ]
      }
    }
  }
}

Running with Docker

First, build the Docker image:

docker build -t baseline-mcp-server .

Configure your MCP client to run the Docker container:

{
  "mcpServers": {
    "baseline-mcp-server": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "baseline-mcp-server:latest"
      ]
    }
  }
}
