How to Connect MongoDB Atlas to an AI Agent
Auth setup
1. In Atlas, go to Organization > Access Manager > API Keys. 2. Create a key pair with the required Atlas roles. 3. Whitelist your agent's IP/CIDR range. 4. For data queries, create a database user under Project > Database Access and use the SRV connection string.
Key facts
| Base URL | https://cloud.mongodb.com/api/atlas/v2/ |
|---|
| API version | Atlas Admin API v2 |
|---|
| Auth | Digest authentication with a Programmatic API Key (public+private key pair) is the Atlas Admin API standard. For data access, use the MongoDB driver with a connection string (SRV URI). The MongoDB MCP server (`mongodb-mcp-server`) accepts a connection string directly. |
|---|
| Scopes | Atlas roles assigned to the API key: Organization Owner, Project Owner, Project Data Access Read Only, etc. |
|---|
| Request body | application/json |
|---|
| Pagination | Offset-based: `itemsPerPage` and `pageNum` query parameters; response wraps results under `results` and has `links` array for navigation. |
|---|
| Rate limit | Atlas Admin API: 100 requests/minute per API key. Returns 429 with Retry-After header. Data plane (via MongoDB driver) is limited by cluster size, not by API key. |
|---|
| Error format | JSON: {"error":401,"errorCode":"...","detail":"...","reason":"..."} — 4xx/5xx HTTP status. |
|---|
Key endpoints
| Method | Path | Description |
|---|
GET | /groups/{groupId}/clusters | List all clusters in a project |
POST | /groups/{groupId}/clusters | Create a new cluster |
GET | /groups/{groupId}/clusters/{clusterName} | Get cluster details |
GET | /groups/{groupId}/databaseUsers | List database users (for data access) |
POST | /groups/{groupId}/accessList | Add an IP to the project access list |
GET | /groups/{groupId}/backup/snapshots/{clusterName} | List cluster snapshots |
Quickstart
GET https://cloud.mongodb.com/api/atlas/v2/groups/{groupId}/clusters
Authorization: Digest {publicKey}:{privateKey}
Accept: application/vnd.atlas.2023-11-15+json
Response: {"results":[{"name":"Cluster0","stateName":"IDLE",...}],"totalCount":1}
Agent pitfalls & tips
- Atlas Admin API uses HTTP Digest auth — not Bearer. This is an uncommon choice and breaks many HTTP clients; use a library that supports it.
- Always set the `Accept: application/vnd.atlas.YYYY-MM-DD+json` header to pin an API version.
- Data-plane operations (CRUD against collections) do NOT go through this API — use a MongoDB driver with the SRV connection string instead.
- Cluster creation is async — poll /clusters/{name} until stateName === "IDLE" before connecting.
- The IP access list must include your agent's outbound IP before connection strings will work.
- For agents, the `mongodb-mcp-server` package wraps both admin and data-plane operations behind a single MCP interface.

How do I authenticate with MongoDB Atlas?
▼
Digest authentication with a Programmatic API Key (public+private key pair) is the Atlas Admin API standard. For data access, use the MongoDB driver with a connection string (SRV URI). The MongoDB MCP server (`mongodb-mcp-server`) accepts a connection string directly. Setup: 1. In Atlas, go to Organization > Access Manager > API Keys. 2. Create a key pair with the required Atlas roles. 3. Whitelist your agent's IP/CIDR range. 4. For data queries, create a database user under Project > Database Access and use the SRV connection string.
What are MongoDB Atlas's API rate limits?
▼
Atlas Admin API: 100 requests/minute per API key. Returns 429 with Retry-After header. Data plane (via MongoDB driver) is limited by cluster size, not by API key.
