Search for files in your Pinata account by name, CID, or MIME type. Returns a list of files matching the given criteria.
AI agents call searchFiles to retrieve information from Pinata MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and queries data from the user's Pinata account without creating, modifying, deleting, or executing any operations. It only returns search results matching specified criteria, which is a read-only operation with minimal security risk.
From the tool's definition Tool name 'searchFiles' and description states it 'Search for files in your Pinata account by name, CID, or MIME type. Returns a list of files matching the given criteria.' This is a query operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access searchFiles 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 searchFiles:
{
"version": "1",
"default": "deny",
"tools": {
"searchFiles": {}
}
}searchFiles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for files in your Pinata account by name, CID, or MIME type. Returns a list of files matching the given criteria. It is categorised as a Read tool in the Pinata MCP MCP Server, which means it retrieves data without modifying state.
Register the Pinata MCP server in PolicyLayer and add a rule for searchFiles: 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.
searchFiles is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the searchFiles 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 searchFiles. 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.
searchFiles 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.
Free to start. No card required.
