WHAT IT DOES

What get_upload_instructions does on Schema Gov It MCP Server

AI agents use get_upload_instructions to create or update resources in Schema Gov It MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Schema Gov It MCP Server environment.

THE RISK

Medium Risk

Why get_upload_instructions needs a policy

The tool facilitates uploading a local RDF file to a server, which is a Write operation (creating/transferring data). The file content is sent to the server, resulting in a new resource (identified by upload_id). It does not delete data, execute arbitrary code, or involve financial transactions.

From the tool's definition Returns the exact curl command to upload a local RDF file to this MCP server and get back an upload_id

POLICY

How to control get_upload_instructions

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_upload_instructions": {
      "limits": [
        {
          "counter": "get_upload_instructions_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

get_upload_instructions stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
