AI agents call deleteFileVectors to permanently remove resources in Pinata MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes vector data associated with a file without undo capability. While the blast radius is somewhat contained (vectors rather than the file itself), the destructive nature and potential for unintended data loss in a production IPFS/Pinata environment justify 'high' severity. Confidence is high due to the unambiguous 'delete' verb in both name and description.
From the tool's definition Tool name 'deleteFileVectors' and description 'Delete vectors for a file' explicitly perform deletion, an irreversible operation on file vector data stored in Pinata's system.
Documented attack patterns abuse exactly the kind of access deleteFileVectors gives an agent:
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 deleteFileVectors:
{
"version": "1",
"default": "deny",
"hide": [
"deleteFileVectors"
]
}deleteFileVectors disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete vectors for a file. 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.
Register the Pinata MCP server in PolicyLayer and add a rule for deleteFileVectors: 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.
deleteFileVectors is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the deleteFileVectors 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 deleteFileVectors. 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.
deleteFileVectors 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.
Start from Pinata MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
