MongoDB MCP Usage

Use the MongoDB MCP server to integrate database queries into workflows.

Read-Only Access

MongoDB MCP is configured in read-only mode. Only queries and data retrieval are supported. No write, update, or delete operations.

Database Queries

Use mcp__mongodb__* tools for:

• Listing databases
• Viewing collection schemas
• Querying collection data
• Analyzing indexes

Integration Pattern

1. List available databases with mcp__mongodb__list_databases
2. Explore collections with mcp__mongodb__list_collections
3. Get schema information with mcp__mongodb__get_collection_schema
4. Query data as needed for analysis
5. Format results for user consumption

Environment Variables

MongoDB MCP requires:

• MONGODB_URI - Connection string (mongodb://...)

Configure in shell before using the plugin.

Cost Considerations

• Minimize database calls when possible
• Use schema queries before running analysis queries
• Cache results locally if multiple calls needed
• Prefer aggregation pipelines for complex operations
