Why update_profile needs a policy

This tool creates or modifies data reversibly. It updates profile metadata (name, status, picture) but does not delete data, execute code, trigger payments, or perform irreversible actions. The blast radius is limited to profile information; a misdirected update could change user-facing data but remains correctable.

From the tool's definition Tool description states 'Update instance profile (name, status text, or picture)' — modifying user profile attributes reversibly without deletion or financial impact.

POLICY

How to control update_profile

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for update_profile:

policy.json

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

update_profile 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.

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
