Xdebug MCP Server

An MCP (Model Context Protocol) server that provides PHP debugging capabilities through Xdebug's DBGp protocol. This allows AI assistants like Claude to directly debug PHP applications. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Xdebug

before you install - you'll need

Set XDEBUG_PORT, LOG_LEVEL, PATH_MAPPINGS, XDEBUG_SOCKET_PATH before connecting.

Claude Code

claude mcp add kpanuragh-xdebug-mcp -- npx -y xdebug-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "kpanuragh-xdebug-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "xdebug-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

06 · Xdebug FAQ

What is Xdebug?

Is Xdebug still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-05. We re-verify nightly.

How do I install Xdebug?

Run `npx -y xdebug-mcp`. The README documents 4 environment variables (XDEBUG_PORT, LOG_LEVEL, PATH_MAPPINGS…) to set first. Set XDEBUG_PORT, LOG_LEVEL, PATH_MAPPINGS, XDEBUG_SOCKET_PATH before connecting. You can also paste the ready-made client config above.

Does Xdebug run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
