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 MongoDB Usage v1.1 – Enhanced

Kaynak: MongoDB Performance Best Practices

Aşama 1: Discovery & Inspection

• Connection: mcp__mongodb__list_databases ile erişimi doğrula.
• Schema Analysis: mcp__mongodb__get_collection_schema ile veri tiplerini ve yapıyı anla.
• Index Check: Mevcut indeksleri listele (list_indexes veya benzeri sorgu ile).

Aşama 2: Query Construction

• Filter: Sorguları indeksli alanlar (Prefix) üzerinden filtrele.
• Projection: Sadece gerekli alanları ({ field: 1 }) seç (Network ve RAM tasarrufu).
• Aggregation: Karmaşık analizler için $match, $group, $project pipeline’ını kur.

Aşama 3: Performance Check (Explain Plan)

• Explain: Sorgunun COLLSCAN (Tam tarama) mı IXSCAN (Index tarama) mı yaptığını kontrol et.
• Optimization: Yavaş sorgular için bileşik indeks (Compound Index) öner.
