AI agents use register_agent_api_agents_register_post to create or modify resources in Agent Registry. 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.
Without a policy, an AI agent could call register_agent_api_agents_register_post repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agent Registry.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Register Agent Register a new AI agent in the Agentry directory. Submit an AI agent for listing. The agent will be added immediately and appear in search results. Optional fields like pricing, features, and integrations improve discoverability. An A2A discovery scan will be triggered automatically if the agent URL is reachable. Responses: 201: Successful Response (Success Response) Content-Type: application/json. It is categorised as a Write tool in the Agent Registry MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agent Registry MCP server in PolicyLayer and add a rule for register_agent_api_agents_register_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.
register_agent_api_agents_register_post is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the register_agent_api_agents_register_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 register_agent_api_agents_register_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.
register_agent_api_agents_register_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.
