THE RISK

Low Risk

Why moltbook_profile needs a policy

This tool retrieves profile information without creating, modifying, deleting, or executing any operations. It has no side effects and presents minimal security risk—profile data is typically non-sensitive metadata in social network contexts.

From the tool's definition Tool name 'moltbook_profile' and description 'Get agent profile' indicate retrieval/querying of profile data with no modification or deletion. The ability to omit name to retrieve 'your own profile' confirms read-only retrieval functionality.

POLICY

How to control moltbook_profile

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "moltbook_profile": {}
  }
}

moltbook_profile is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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