MongoDB

MongoDB (Self-Managed MCP)

For deployments you manage yourself — Community, Enterprise Advanced, a local dev container, or an Atlas cluster — this plugin connects your agent using nothing more than a connection string. It runs the MongoDB MCP server locally via npx, giving your agent tools to explore databases and collections, run queries and aggregations, and manage indexes.

To get started, see the Community & Enterprise Advanced setup guide.

Skills

These skills come bundled with the plugin and activate automatically when relevant:

• mongodb-mcp-setup — Walks you through configuring the MCP server's connection string and environment variables.
• mongodb-connection — Reviews and tunes client connection configuration (pools, timeouts, patterns) across driver languages.
• mongodb-natural-language-querying — Turns natural-language requests into read-only find queries and aggregation pipelines.
• mongodb-qe-size-estimation — Estimates the storage and memory impact of encrypting fields in collections with Queryable Encryption (QE) enabled. Doesn't apply to collections that use Client-Side Field Level Encryption (CSFLE).
• mongodb-query-optimizer — Diagnoses slow queries and recommends indexes to fix them.
• mongodb-schema-design — Applies MongoDB schema design patterns and steers you clear of common anti-patterns, whether modeling from scratch or migrating from SQL.
• mongodb-search-and-ai — Helps build Atlas Search (full-text), Vector Search (semantic), and hybrid search implementations.
• mongodb-atlas-stream-processing — Manages Atlas Stream Processing workspaces, connections, and processors for streaming workloads.
