furey/mongodb-lens

npx -y mongodb-lens   # default mongodb://localhost:27017
npx -y mongodb-lens mongodb://your-connection-string
docker run --rm -i --network=host furey/mongodb-lens mongodb://your-connection-string

Usage

• •Ask things like 'Show me all users older than 30' — the client picks find-documents, aggregate-data, etc.
• •Manage connections with named aliases in ~/.mongodb-lens.jsonc (multiple MongoDB URIs)
• •Destructive operations are gated by a two-step 4-digit confirmation token

Key features

• ✓40+ tools: find, insert, update, delete, aggregate, schema analysis, explain-query, index management, transactions, watch-changes, GridFS
• ✓Resources (schemas, indexes, stats, replica status) and prompts (query-builder, query-optimizer, security-audit, sql-to-mongodb)
• ✓Multiple connections, smart caching, auto-reconnection, credential obfuscation and a token-based confirmation system
• ✓Runs via NPX, Docker Hub image, or from source; supports older MongoDB via driver pinning

Best for

Developers and DBAs who want to query, explore and optimize MongoDB through natural language from their MCP client.

Caveats

• ⚠Data flows to your remote LLM provider — use projection, read-only users and backup instances for sensitive data
• ⚠Confirmation bypass (CONFIG_DISABLE_DESTRUCTIVE_OPERATION_TOKENS) removes a safety mechanism
• ⚠Inserted metadata collection persists in each newly created database until manually dropped
