WHEN AI AGENTS USE THIS TOOL

AI agents call rules to perform operations in Apollo GraphQL. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.

WHY ENFORCE A POLICY ON RULES

Applying a policy to rules gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.

RECOMMENDED POLICY

Apply a rate limit to control usage and monitor for unexpected behaviour.

apollo-graphql.yaml 
tools:
  rules:
    rules:
      - action: allow
        rate_limit:
          max: 60
          window: 60

How do I enforce a policy on rules?

Add a rule in your Intercept YAML policy under the tools section for rules. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Apollo GraphQL MCP server.
