Mern-Chat-App MCP Server

This is a standalone Model Context Protocol server generated for the Mern-Chat-App repository. It bundles a filtered copy of the repository's source files plus a Claude-generated architecture overview and per-file summaries, and exposes them as MCP tools:

• list_files(pattern?) — list bundled files, optionally filtered by glob (e.g. *.py)

• read_file(path) — read a file's contents

• search_code(query, regex?, max_results?) — search across the bundled source

• get_repo_overview() — the Claude-generated architecture overview

• get_file_summary(path) — the Claude-generated summary for one file

This server has no dependency on Claude, Anthropic, or any external API at runtime — it only needs the mcp package, and works with any MCP-compatible client (Claude Desktop, Claude Code, or any other agent that can launch a stdio MCP server).

Run it

pip install -r requirements.txt   # or: pip install "mcp[cli]"
python server.py

Use it from Claude Desktop / Claude Code

Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "mern-chat-app": {
      "command": "python",
      "args": ["/absolute/path/to/mern-chat-app-mcp-server/server.py"]
    }
  }
}

Or with the Claude Code CLI:

claude mcp add mern-chat-app -- python /absolute/path/to/mern-chat-app-mcp-server/server.py

Any other MCP-compatible agent that can launch a stdio child process can use this the same way.

Try it standalone

mcp dev server.py

This opens the MCP Inspector so you can call the tools manually before wiring it into an agent.
