MongoDB MCP Server

A Model Context Protocol server for interacting with MongoDB Databases and MongoDB Atlas. Its 40 documented tools cover atlas, collection, many, cluster. It runs locally over stdio via the published package.

People who work with atlas, collection and many and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install MongoDB MCP Server

before you install - you'll need

Set MDB_MCP_CONNECTION_STRING, MDB_MCP_API_CLIENT_ID, MDB_MCP_API_CLIENT_SECRET, MDB_MCP_READ_ONLY before connecting.

Claude Code

claude mcp add mongodb-js-mongodb-mcp-server -- npx -y mongodb-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mongodb-js-mongodb-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · container (OCI image) - can be sandboxed away from your filesystem

license Apache-2.0 - declared in the repository

npm package mongodb-mcp-server - unscoped; check the name against the project README before installing

registry namespace io.github.mongodb-js is GitHub-verified and matches the repo owner
