mongodb/mongodb-schema-design

Patrons et anti-patrons de conception de schéma MongoDB. À utiliser lors de la conception de modèles de données, la révision de schémas, la migration depuis SQL ou le diagnostic de problèmes de performance liés aux schémas.

Qu'est-ce que mongodb-schema-design ?

Cette compétence MongoDB fournit des conseils complets sur la conception de schémas, couvrant les modèles de données documentaires, les critères de choix entre embedding et référencement, et la gestion des relations one-to-many, many-to-many et hiérarchiques. Elle est utile aux développeurs qui migrent depuis des bases de données SQL, aux architectes qui conçoivent des modèles de données évolutifs, et à toute personne confrontée à des problèmes de performance ou au dépassement de la limite de 16 Mo. La compétence détaille les anti-patrons courants comme les tableaux illimités, l'explosion d'index et les index inutiles, et présente des patrons avancés tels que l'approximation, le versionnage de documents et la gestion du cycle de vie des données (TTL). Elle s'applique à tous les outils d'IA qui utilisent MongoDB (Claude Code, Cursor, Codex, etc.) et exploite la documentation officielle et l'expertise collective de la communauté pour fournir des recommandations contextuelles et applicables immédiatement.

Individual skills in this repo

This repo contains 5 individual skills — each has its own dedicated page.

mongodb/mongodb-connection

Optimize MongoDB client connection configuration (pools, timeouts, patterns) for any supported driver language. Use this skill when working/updating/reviewing on functions that instantiate or configure a MongoDB client (eg, when calling `connect()`), configuring connection pools, troubleshooting connection errors (ECONNREFUSED, timeouts, pool exhaustion), optimizing performance issues related to connections. This includes scenarios like building serverless functions with MongoDB, creating API endpoints that use MongoDB, optimizing high-traffic MongoDB applications, creating long-running tasks and concurrency, or debugging connection-related failures.

mongodb/mongodb-mcp-setup

Guide users through configuring key MongoDB MCP server options. Use this skill when a user has the MongoDB MCP server installed but hasn't configured the required environment variables, or when they ask about connecting to MongoDB/Atlas and don't have the credentials set up.

mongodb/mongodb-natural-language-querying

Generate read-only MongoDB queries (find) or aggregation pipelines using natural language, with collection schema context and sample documents. Use this skill whenever the user asks to write, create, or generate MongoDB queries, wants to filter/query/aggregate data in MongoDB, asks "how do I query...", needs help with query syntax, or discusses finding/filtering/grouping MongoDB documents. Also use for translating SQL-like requests to MongoDB syntax. Does NOT handle Atlas Search ($search operator), vector/semantic search ($vectorSearch operator), fuzzy matching, autocomplete indexes, or relevance scoring - use search-and-ai for those. Does NOT analyze or optimize existing queries - use mongodb-query-optimizer for that. Does NOT handle aggregation pipelines that involve write operations. Requires MongoDB MCP server.

mongodb/mongodb-query-optimizer

Help with MongoDB query optimization and indexing. Use only when the user asks for optimization or performance: "How do I optimize this query?", "How do I index this?", "Why is this query slow?", "Can you fix my slow queries?", "What are the slow queries on my cluster?", etc. Do not invoke for general MongoDB query writing unless user asks for performance or index help. Prefer indexing as optimization strategy. Use MongoDB MCP when available.

mongodb/mongodb-search-and-ai

Guides MongoDB users through implementing and optimizing Atlas Search (full-text), Vector Search (semantic), and Hybrid Search solutions. Use this skill when users need to build search functionality for text-based queries (autocomplete, fuzzy matching, faceted search), semantic similarity (embeddings, RAG applications), or combined approaches. Also use when users need text containment, substring matching ('contains', 'includes', 'appears in'), case-insensitive or multi-field text search, or filtering across many fields with variable combinations. Provides workflows for selecting the right search type, creating indexes, constructing queries, and optimizing performance using the MongoDB MCP server.
