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
- List available databases with
mcp__mongodb__list_databases - Explore collections with
mcp__mongodb__list_collections - Get schema information with
mcp__mongodb__get_collection_schema - Query data as needed for analysis
- 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
