AI agents use create_compel to create or modify resources in Compeller. 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 create_compel 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 Compeller.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so create_compel only ever does what you allow.

What does the create_compel tool do? +

Create a Compeller generation job from primary audio media and optional reference media. Returns compel id, status, and links to track progress and retrieve renderings.. It is categorised as a Write tool in the Compeller MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_compel? +

Register the Compeller MCP server in PolicyLayer and add a rule for create_compel: 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 Compeller. Nothing to install.

What risk level is create_compel? +

create_compel is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_compel? +

Yes. Add a rate_limit block to the create_compel 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.

How do I block create_compel completely? +

Set action: deny in the PolicyLayer policy for create_compel. 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.

What MCP server provides create_compel? +

create_compel is provided by the Compeller MCP server (https://compeller.ai/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Compeller tool call.
