AI agents use create_api_key to create or update resources in MCP Server for Coroot — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Server for Coroot environment.
This tool creates a new API key, which is a reversible write operation that generates a credential. While API keys are sensitive and granting access to them carries security implications, the tool itself creates new data (the key) rather than executing code, deleting resources, or moving money.
From the tool's definition Tool name 'create_api_key' and description 'Create a new API key for data ingestion' indicate creation of a credential/authentication token.
Documented attack patterns abuse exactly the kind of access create_api_key gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server for Coroot, and nothing reaches the server without passing your rules. This is the rule we recommend for create_api_key:
{
"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.

create_api_key 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 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.
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.
