MongoDB
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
Integrations
Provides access to MongoDB databases, allowing LLMs to inspect collection schemas and execute MongoDB operations like queries, aggregations, updates, inserts, and creating indexes
MCP MongoDB Server
A Model Context Protocol server that provides access to MongoDB databases. This server enables LLMs to inspect collection schemas and execute MongoDB operations.

Features
Read-Only Mode
- Connect to MongoDB in read-only mode with
--read-only
or-r
flag - Prevents write operations (update, insert, createIndex)
- Uses MongoDB's secondary read preference for optimal read performance
- Provides additional safety for production database connections
Resources
- List and access collections via
mongodb://
URIs - Each collection has a name, description and schema
- JSON mime type for schema access

Installation for Development
Using Claude Desktop
To use with Claude Desktop, add the server config:
On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json
Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:
The Inspector will provide a URL to access debugging tools in your browser.
Components
Resources
The server provides schema information for each collection in the database:
- Collection Schemas (
mongodb://<host>/<collection>/schema
)- JSON schema information for each collection
- Includes field names and data types
- Automatically inferred from collection documents
Usage with Claude Desktop
To use this server with the Claude Desktop app, add the following configuration to the "mcpServers" section of your claude_desktop_config.json
:
Installing via Smithery
To install MCP MongoDB Server for Claude Desktop automatically via Smithery:
Installing via mcp-get
You can install this package using mcp-get:
Replace /sample_namespace
with your database name.
Using Read-Only Mode
You can connect to MongoDB in read-only mode by adding the --read-only
or -r
flag when starting the server. This is recommended when you need to protect your data from accidental writes or when connecting to production databases.
When in read-only mode:
- All write operations (update, insert, createIndex) will be blocked
- The server connects using MongoDB's secondary read preference
- The connection status indicates read-only mode is active
- The
ping
andserverInfo
responses include read-only status information
