AI agents invoke trigger_scan_api_scanner_scan_post to trigger processes or run actions in Agent Registry. 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.
trigger_scan_api_scanner_scan_post 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.

Trigger Scan Scan domains for A2A Agent Card discovery. Checks the given domains for /.well-known/agent.json endpoints and extracts agent capability metadata. Results are stored and can be retrieved via the scan results endpoint. Responses: 202: Successful Response (Success Response) Content-Type: application/json. It is categorised as a Execute tool in the Agent Registry MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Agent Registry MCP server in PolicyLayer and add a rule for trigger_scan_api_scanner_scan_post: 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 Agent Registry. Nothing to install.
trigger_scan_api_scanner_scan_post 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 trigger_scan_api_scanner_scan_post 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 trigger_scan_api_scanner_scan_post. 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.
trigger_scan_api_scanner_scan_post is provided by the Agent Registry MCP server (agentry/agent-registry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
