Why create_api_key needs a policy

This tool creates new API credentials, which modifies the security posture of the system by introducing new authentication tokens. While reversible (keys can be deleted via delete_api_key), creating API keys is a write operation that extends access capabilities and should be tightly controlled to prevent unauthorized credential generation.

From the tool's definition Tool name is 'create_api_key' and description states 'Create a new API key'. The verb 'create' indicates data creation. API keys are credentials that enable authentication and access control.

POLICY

How to control create_api_key

PolicyLayer is an MCP gateway — it sits between your AI agents and AnythingLLM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_api_key:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_api_key": {
      "limits": [
        {
          "counter": "create_api_key_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_api_key stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about create_api_key

What does the create_api_key tool do? +

Create a new API key. It is categorised as a Write tool in the AnythingLLM MCP Server 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_api_key? +

Register the AnythingLLM MCP Server MCP server in PolicyLayer and add a rule for create_api_key: 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 AnythingLLM MCP Server. Nothing to install.

What risk level is create_api_key? +

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

Can I rate-limit create_api_key? +

Yes. Add a rate_limit block to the create_api_key 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_api_key completely? +

Set action: deny in the PolicyLayer policy for create_api_key. 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_api_key? +

create_api_key is provided by the AnythingLLM MCP Server MCP server (raqueljezweb/anythingllm-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AnythingLLM MCP Server tool call.

Start from AnythingLLM MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
