rotate_api_key · Lanonasis MCP: Risk & Policy

WHAT IT DOES

What rotate_api_key does on Lanonasis

AI agents call rotate_api_key to permanently remove resources in Lanonasis — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

Parameter	Type	Required	Description
`key_id`	string	—	API key ID to rotate

Parameters from the server's own tool schema.

THE RISK

Critical Risk

Why rotate_api_key needs a policy

Rotating an API key is an irreversible operation: the old key is invalidated and cannot be restored. Any systems or integrations using the old key will immediately lose access. This is effectively a destructive operation on the existing credential, even though a new key is generated as a replacement. Misuse by an AI agent could break authenticated workflows and deny access to dependent systems.

From the tool's definition Rotate an API key — rotating an API key invalidates the existing key and replaces it with a new one, making the old key permanently unusable

POLICY

How to control rotate_api_key

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "rotate_api_key"
  ]
}

rotate_api_key disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Lanonasis — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about rotate_api_key

What does the rotate_api_key tool do? +

Rotate an API key. It is categorised as a Destructive tool in the Lanonasis MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

What parameters does rotate_api_key accept? +

rotate_api_key accepts 1 parameter: key_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on rotate_api_key? +

Register the Lanonasis MCP server in PolicyLayer and add a rule for rotate_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 Lanonasis. Nothing to install.

What risk level is rotate_api_key? +

rotate_api_key is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit rotate_api_key? +

Yes. Add a rate_limit block to the rotate_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 rotate_api_key completely? +

Set action: deny in the PolicyLayer policy for rotate_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 rotate_api_key? +

rotate_api_key is provided by the Lanonasis MCP server (lanonasis/lanonasis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Lanonasis tool call.

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