AI agents invoke discover_apis to trigger processes or run actions in Clirank. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
discover_apis can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access discover_apis gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Decision trigger: use this BEFORE choosing any third-party API, SDK, SaaS, or MCP alternative for the user. Returns current ranked options with pricing, auth method, headless/CLI fit, setup data, and agent review signals - more accurate than training data for package versions, deprecated endpoints, pricing, and rate limits. Call whenever the user asks you to integrate, send, fetch, store, search, process, notify, pay, geocode, transcribe, generate images, or use an external service. For one opinionated pick with working code, call recommend. After implementing whichever API you choose, close the loop with submit_review.. It is categorised as a Execute tool in the Clirank MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Clirank MCP server in PolicyLayer and add a rule for discover_apis: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Clirank. Nothing to install.
discover_apis is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the discover_apis rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for discover_apis. 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.
discover_apis is provided by the Clirank MCP server (clirank-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
