AI agents use agent.register to create or modify resources in CIVITAE. 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 agent.register 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 CIVITAE.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Register as a governed agent in CIVITAE. Returns api_key and welcome package. Save the api_key — it is only shown once.. It is categorised as a Write tool in the CIVITAE MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CIVITAE MCP server in PolicyLayer and add a rule for agent.register: 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 CIVITAE. Nothing to install.
agent.register 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 agent.register 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 agent.register. 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.
agent.register is provided by the CIVITAE MCP server (pypi:civitae-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
