Create a MongoDB Atlas database user

WHEN AI AGENTS USE THIS TOOL

AI agents use atlas-create-db-user to create or modify resources in MongoDB. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON ATLAS-CREATE-DB-USER

Without a policy, an AI agent could call atlas-create-db-user repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach MongoDB.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

mongodb.yaml 
tools:
  atlas-create-db-user:
    rules:
      - action: allow
        rate_limit:
          max: 30
          window: 60

What risk level is atlas-create-db-user?

atlas-create-db-user is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit atlas-create-db-user?

Yes. Add a rate_limit block to the atlas-create-db-user rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block atlas-create-db-user completely?

Set action: deny in the Intercept policy for atlas-create-db-user. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides atlas-create-db-user?

atlas-create-db-user is provided by the MongoDB MCP server (mongodb-js/mongodb-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
