MongoDB advises passing connection strings and API credentials as environment variables, not command-line arguments. ## Ask your coding agent ```text Connect the MongoDB MCP server to my coding agent using its documented setup: https://github.com/mongodb-js/mongodb-mcp-server. ``` ## What it does The MongoDB MCP server is MongoDB's own server for connecting AI agents to MongoDB. With a connection string, the agent can list databases and collections, infer a collection's schema, run find, count and aggregation queries, explain a query plan, and read indexes and storage sizes. Write tools insert, update and delete documents, create collections and indexes, and drop them, and an export tool saves query results to a file. MongoDB's server also manages MongoDB Atlas through the Atlas API. The agent can list and inspect organizations, projects and clusters, create a free cluster, add database users and IP access entries, load sample data, pause or upgrade a cluster, read alerts and the performance advisor, and work with Atlas Stream Processing. Atlas Local tools create and connect to a local Atlas deployment in Docker, and assistant tools search MongoDB's knowledge sources. The server runs locally through npx with Node.js 22.13 or newer, or in Docker. MongoDB also runs a managed Atlas MCP server reached through its mongodb-atlas plugin with OAuth. All of MongoDB's setup examples start in read-only mode. The GitHub repo had 1,138 stars on 2026-10-01. Tools it gives your agent: `find`, `aggregate`, `count`, `collection-schema`, `collection-indexes`, `explain`, `insert-many`, `update-many`, `create-index`, `atlas-list-clusters`, `atlas-create-free-cluster`, `atlas-get-performance-advisor` ## When to use it - You want the agent to understand the real shape of your documents before it writes queries. - You need an aggregation pipeline written and checked against your data. - You want to create a free Atlas cluster and a database user for a new project from your editor. - You want to see slow queries and index suggestions from the Atlas performance advisor. ## When to pick something else - Running without read-only mode on important data: write tools can delete many documents or drop whole databases, so keep --readOnly unless you need writes. ## What it needs - Node.js 22.13 or newer, or Docker - A MongoDB connection string, or Atlas service account credentials for Atlas tools ## Questions people ask ### Is the MongoDB MCP server free? Yes. It is open source under Apache-2.0. You pay only for MongoDB itself, and Atlas has a free cluster tier (pricing page, 2026-10-01). ### Can the MongoDB MCP server delete data? Yes, unless you run it read-only. Its tools include delete-many, drop-collection and drop-database. The --readOnly flag or MDB_MCP_READ_ONLY=true removes every create, update and delete tool. ### Does it work with self-hosted MongoDB, not only Atlas? Yes. The local server connects to any MongoDB deployment by connection string; the Atlas tools are extra and need Atlas credentials. ## Related ### Other MCP servers for databases - [DBHub](https://cookiesforai.app/mcp/dbhub): DBHub is an open-source MCP server by Bytebase that gives AI agents SQL access to PostgreSQL, MySQL, MariaDB, SQL Server, Oracle and SQLite through one server with two default tools. - [Neon](https://cookiesforai.app/mcp/neon): The Neon MCP server gives AI agents control of Neon serverless Postgres: create projects and branches, run SQL, inspect schemas, find slow queries and run migrations on a branch before applying them. - [Postgres MCP Pro](https://cookiesforai.app/mcp/postgres-mcp-pro): Postgres MCP Pro is an open-source MCP server that gives AI agents access to a PostgreSQL database, with schema browsing, safe SQL execution, EXPLAIN plans, index recommendations and database health checks. - [Redis](https://cookiesforai.app/mcp/redis): The Redis MCP server gives AI agents natural-language access to a Redis database: strings, hashes, lists, sets, sorted sets, streams, JSON documents, pub/sub and vector search indexes.
