THE RISK

Critical Risk

Why cancelPinRequest needs a policy

Cancelling a pin request is an irreversible action that stops and removes a pending pinning operation. Once cancelled, the pin request cannot be restored, making this a destructive action. The blast radius is medium since it affects IPFS content availability but doesn't delete the underlying data.

From the tool's definition Cancel a pending pin by CID request

How to control cancelPinRequest

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

policy.json

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

cancelPinRequest 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 Pinata MCP — 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 cancelPinRequest

What does the cancelPinRequest tool do? +

Cancel a pending pin by CID request. It is categorised as a Destructive tool in the Pinata MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on cancelPinRequest? +

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

What risk level is cancelPinRequest? +

cancelPinRequest 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 cancelPinRequest? +

Yes. Add a rate_limit block to the cancelPinRequest 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 cancelPinRequest completely? +

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

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

Enforce policy on every Pinata MCP tool call.

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