MongoDB MCP Server config

Add this to your MCP client's config, or use the install line.

Install

claude mcp add-json mongodb '{"command":"npx","args":["-y","mongodb-mcp-server@latest","--readOnly"],"env":{"MDB_MCP_CONNECTION_STRING":"mongodb://localhost:27017/myDatabase"}}'

Check it before you connect it. An MCP server runs with your permissions. Replace placeholder keys with your own and never share them.
