概要

What is MongoDB MCP Server?

The MongoDB MCP Server is a Model Context Protocol implementation that bridges Claude with MongoDB databases. It enables Claude to perform a wide range of MongoDB operations—including querying, aggregation, data manipulation (CRUD), and database management—directly from a conversation. It is designed for users of Claude Desktop or Cursor who need to interact with MongoDB through AI.

How to use MongoDB MCP Server?

Install prerequisites (Node.js v14+, access to a MongoDB instance, and Claude Desktop or Cursor). Clone the repository, install dependencies with npm install, then configure the MCP client (Claude Desktop or Cursor) by adding an entry in its MCP settings with the absolute path to mongo-mcp-server.js and environment variables: MONGODB_URI (required) and optional DEFAULT_DATABASE. Restart the client to load the server.

Key features of MongoDB MCP Server

  • Comprehensive MongoDB operations: find, aggregate, count, distinct, sample.
  • CRUD support: insert, update, delete documents (single or bulk).
  • Database management: list databases, list collections, drop collections.
  • Query analysis via explain tool for aggregation pipelines.
  • Flexible database selection per operation (defaults to DEFAULT_DATABASE).
  • Secure connection using environment variables for credentials.

Use cases of MongoDB MCP Server

  • Query and analyze documents in a collection through natural language.
  • Insert, update, or delete documents without writing MongoDB queries manually.
  • Run aggregation pipelines and get execution plans for performance insights.
  • Manage collections and databases (list, drop) during conversations.
  • Count documents or get distinct values for a field across a database.

よくある質問

1

What runtime and dependencies are required?

Node.js v14 or newer, a MongoDB instance (local or Atlas), and the Claude Desktop or Cursor application. The server uses the MongoDB Node.js driver.

2

How is the connection string configured?

The `MONGODB_URI` environment variable must be set to a valid MongoDB connection string. The `DEFAULT_DATABASE` environment variable is optional and sets the default database if no `database` parameter is provided in a tool call.

3

Where does data live?

Data remains in the MongoDB instance specified by the connection string. The server does not store any data locally; it only acts as a bridge.

4

What are the known limits or constraints?

The `sample` tool has a default count of 5 and a maximum of 10. The `find` tool has a default limit of 10 and a maximum of 100. The `dropCollection` tool requires a `confirm` boolean parameter set to `true` to proceed.

5

What transport and authentication are used?

The server uses the MCP protocol over standard I/O (stdio) for communication with Claude. Authentication to MongoDB is handled via the connection string in the `MONGODB_URI` environment variable; no other authentication mechanism is provided.
