kiliczsh/mcp-mongo-server

A Model Context Protocol (MCP) server that lets AI assistants work with your MongoDB databases. It exposes your collections, infers their schemas, and runs queries, aggregations, and writes through a standard interface — so tools like Claude Desktop and Cursor can read and reason about your data.

Features

  • Read-Only Mode — blocks every write path (insert, update, index creation, and aggregation stages like $out/$merge that could modify data).

  • Smart ObjectId Handling — configurable auto/none/force conversion of 24-character hex strings to ObjectIds.

  • Schema Inference — automatic collection schema detection from document samples.

  • Query & Aggregation — full query and aggregation pipeline support, with optional explain plans.

  • Write Operations — insert, update, and index creation (when read-only mode is off).

  • Time Conversion — a convertTime helper turns Unix timestamps and date strings into UTC/GMT/ISO, so date queries stay unambiguous across timezones.

  • Progress & Cancellation — long operations report progress and can be cancelled mid-flight.

  • Two Transports — run locally over stdio, or expose an HTTP endpoint for remote access.
