Generate a temporary download link for accessing a private IPFS file from Pinata
AI agents call createPrivateDownloadLink 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.
This tool generates a temporary access link for a private file — it reads/retrieves access credentials/URLs rather than modifying data. However, it does grant temporary access to private content, which carries medium severity since misuse could expose private files to unintended parties.

Documented attack patterns abuse exactly the kind of access createPrivateDownloadLink 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 createPrivateDownloadLink:
{
"version": "1",
"default": "deny",
"tools": {
"createPrivateDownloadLink": {}
}
}createPrivateDownloadLink is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

createPrivateDownloadLink 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.
