 # Elasticsearch MCP Server
 
-Connect to your Elasticsearch data directly from any MCP Client (like Claude Desktop) using the Model Context Protocol (MCP).
-
-This server connects agents to your Elasticsearch data using the Model Context Protocol (MCP). It allows you to interact with your Elasticsearch indices through natural language conversations.
-
-## Features
-
-* **List Indices**: View all available Elasticsearch indices
-* **Get Mappings**: Inspect field mappings for specific indices
-* **Search**: Execute Elasticsearch queries using full Query DSL capabilities with automatic highlighting
-
-## Prerequisites
-
-* Node.js (v22+)
-* An Elasticsearch instance
-* Elasticsearch API key with appropriate permissions
-* Claude Desktop App (free version is sufficient)
-
-## Installation & Setup
-
-### Using the Published NPM Package
-
-The easiest way to use Elasticsearch MCP Server is through the published npm package:
-
-1. **Configure Claude Desktop App**
-   - Open Claude Desktop App
-   - Go to Settings > Developer > MCP Servers
-   - Click `Edit Config` and add a new MCP Server with the following configuration to your `claude_desktop_config.json`:
-
-```json
-{
-  "mcpServers": {
-    "elasticsearch-mcp-server": {
-      "command": "npx",
-      "args": [
-        "-y",
-        "mcp-server-elasticsearch"
-      ],
-      "env": {
-        "ES_URL": "your-elasticsearch-url",
-        "ES_API_KEY": "your-api-key"
-      }
-    }
-  }
-}
-```
-
-2. **Start a Conversation**
-   - Open a new conversation in Claude Desktop App
-   - The MCP server should connect automatically
-   - You can now ask Claude questions about your Elasticsearch data
-
-### Developing Locally
-
-If you want to develop or modify the server locally:
-
-1. **Use the correct Node.js version**
-```bash
-nvm use
-```
-
-2. **Install Dependencies**
-```bash
-npm install
-```
-
-3. **Build the Project**
-```bash
-npm run build
-```
-
-4. **Configure Claude Desktop for local development**
-   - Open Claude Desktop App
-   - Go to Settings > Developer > MCP Servers
-   - Click `Edit Config` and add a new MCP Server with the following configuration:
-
-```json
-{
-  "mcpServers": {
-    "Elasticsearch MCP Server (Local)": {
-      "command": "node",
-      "args": [
-        "/path/to/your/project/dist/index.js"
-      ],
-      "env": {
-        "ES_URL": "your-elasticsearch-url",
-        "ES_API_KEY": "your-api-key"
-      }
-    }
-  }
-}
-```
-
-5. **Debugging**
-```bash
-npm run inspector
-```
-
-## Example Questions
-
-* "What indices do I have in my Elasticsearch cluster?"
-* "Show me the field mappings for the 'products' index"
-* "Find all orders over $500 from last month"
-* "Which products received the most 5-star reviews?"
-
-## How It Works
-
-When you ask Claude a question about your data:
-1. Claude analyzes your request and determines which Elasticsearch operations are needed
-2. The MCP server carries out these operations (listing indices, fetching mappings, performing searches)
-3. Claude processes the results and presents them in a user-friendly format
-
-## Security Best Practices
-
-You can create a dedicated Elasticsearch API key with minimal permissions to control access to your data:
-
-```
-POST /_security/api_key
-{
-  "name": "es-mcp-server-access",
-  "role_descriptors": {
-    "claude_role": {
-      "cluster": [
-        "monitor"
-      ],
-      "indices": [
-        {
-          "names": [
-            "index-1",
-            "index-2",
-            "index-pattern-*"
-          ],
-          "privileges": [
-            "read",
-            "view_index_metadata"
-          ]
-        }
-      ]
-    }
-  }
-}
-```
-
-## Troubleshooting
-
-* If the server isn't connecting, check that your MCP configuration is correct
-* Ensure your Elasticsearch URL is accessible from your machine
-* Verify that your API key has the necessary permissions
-* Check the terminal output for any error messages
