## About MongoDB MCP Server
MongoDB's official MCP server connects AI agents to MongoDB databases and MongoDB Atlas. It runs locally against any self-managed deployment, optionally in read-only mode, and ships in official MongoDB plugins for Cursor, VS Code, Claude, Codex and GitHub Copilot CLI; MongoDB recommends its hosted Atlas MCP server over OAuth for Atlas users.

## Connect to an MCP client
Launch command from the project's README: `MDB_MCP_CONNECTION_STRING=mongodb://localhost:27017/myDatabase npx -y mongodb-mcp-server@latest --readOnly`

### Claude Code (Run in your terminal)

```shell
claude mcp add mongodb-mcp-server -e MDB_MCP_CONNECTION_STRING=mongodb://localhost:27017/myDatabase -- npx -y mongodb-mcp-server@latest --readOnly
```

### Cursor (~/.cursor/mcp.json or .cursor/mcp.json)

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

### VS Code (.vscode/mcp.json)

```json
{
  "servers": {
    "mongodb-mcp-server": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "mongodb-mcp-server@latest", "--readOnly"],
      "env": {
        "MDB_MCP_CONNECTION_STRING": "mongodb://localhost:27017/myDatabase"
      }
    }
  }
}
```

### Claude Desktop (claude_desktop_config.json)

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

### Codex (~/.codex/config.toml)

```toml
[mcp_servers.mongodb-mcp-server]
command = "npx"
args = ["-y", "mongodb-mcp-server@latest", "--readOnly"]
env = { MDB_MCP_CONNECTION_STRING = "mongodb://localhost:27017/myDatabase" }
```
