mongo

This MCP server exposes MongoDB querying capabilities through MCP tools. The primary tool available is get-collection-documents, which retrieves documents from a specified collection within a database. To use it, provide the collection name and database name; the server will return a list of documents present in that collection. The tool is useful for quick data inspection, debugging queries, and integrating MongoDB data retrieval into larger MCP workflows.

Prerequisites:

• Node.js and npm installed on your machine
• Network access to the MongoDB instance you intend to query

Installation steps:

1. Ensure npm is up to date:

npm install -g npm

2. Install or run the MCP server via npx (no local install required):

npx -y mongo-mcp-server

3. Alternatively, install the package locally or globally if you prefer:

npm install mongo-mcp-server

4. Configure the MongoDB connection string via environment variables (see mcp_config for env vars).
5. Start the server and begin issuing MCP tool calls (e.g., get-collection-documents).

Note: If your environment requires authentication or TLS, ensure MONGO_URI provides the appropriate connection string.

Environment variables:

• MONGO_URI: Required. The MongoDB connection string. Example: mongodb://user:password@host:27017/database Common issues:
• Unable to connect: verify network access to MongoDB, correct host/port, and authentication credentials in MONGO_URI.
• Missing collection or database: ensure the collection and database names are correct and exist.
• Timeouts: consider increasing server timeout settings if querying large collections. Configuration options may vary depending on the MCP server implementation; consult the project's docs for any additional flags or capabilities.
