MongoDB Connector

Supported MongoDB Atlas Administration connector for projects, clusters, and database-user metadata. Atlas retired its hosted Data API, so this connector does not pretend to query collection data over that discontinued service.

Credential setup

bearer

Use a short-lived access token from a least-privilege Atlas service account. Atlas retired the App Services Data API; direct collection queries require a MongoDB driver or a private bridge.

Setup docs: https://www.mongodb.com/docs/atlas/api/service-accounts/generate-oauth2-token/

After adding this connector, attach the credential on the server page, then run astrail tools list.

Hosted MCP endpoint

/api/mcp/preset-mongodb

Private servers require an Astrail API key in the Authorization header.

Astrail does not evaluate generated TypeScript inside Next.js. Hosted calls are routed through stored tool metadata and endpoint maps.
