## About

MongoDB's official MCP server lets agents query and modify MongoDB databases and manage Atlas clusters, users and access lists. It runs locally via npx or Docker using a connection string and/or Atlas service account credentials, with a read-only mode available. An Atlas-managed OAuth remote server is also offered through client plugin marketplaces.

## Install

1. **Add the server to Codex**

   Codex CLI:

   ```bash
   codex mcp add mongodb --env MDB_MCP_CONNECTION_STRING=YOUR_MDB_MCP_CONNECTION_STRING --env MDB_MCP_API_CLIENT_ID=YOUR_MDB_MCP_API_CLIENT_ID --env MDB_MCP_API_CLIENT_SECRET=YOUR_MDB_MCP_API_CLIENT_SECRET -- npx -y mongodb-mcp-server@latest --readOnly
   ```

   config.toml:

   ```toml
   [mcp_servers.mongodb]
   command = "npx"
   args = ["-y", "mongodb-mcp-server@latest", "--readOnly"]
   
   [mcp_servers.mongodb.env]
   MDB_MCP_CONNECTION_STRING = "YOUR_MDB_MCP_CONNECTION_STRING"
   MDB_MCP_API_CLIENT_ID = "YOUR_MDB_MCP_API_CLIENT_ID"
   MDB_MCP_API_CLIENT_SECRET = "YOUR_MDB_MCP_API_CLIENT_SECRET"
   ```

   Agents SDK:

   ```python
   from agents import Agent, Runner
   from agents.mcp import MCPServerStdio
   
   async with MCPServerStdio(
       name="MongoDB",
       params={"command": "npx", "args": ["-y", "mongodb-mcp-server@latest", "--readOnly"]},
   ) as server:
       agent = Agent(name="Assistant", mcp_servers=[server])
       result = await Runner.run(agent, "List the collections in the shop database")
       print(result.final_output)
   ```
