set_profile_ttl · Ogham MCP: Risk & Policy

WHAT IT DOES

What set_profile_ttl does on Ogham

AI agents use set_profile_ttl to create or update resources in Ogham — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ogham environment.

WHY IT NEEDS A POLICY

Why set_profile_ttl needs a policy

This tool creates or modifies data (profile TTL configuration) reversibly—TTL values can be changed again later. It does not delete data irreversibly, execute arbitrary code, or move money. The empty description reduces confidence slightly, but the name and context of a memory management system clearly indicate a Write operation.

From the tool's definition Tool name 'set_profile_ttl' indicates modification of a profile's time-to-live setting. The server manages persistent shared memory with profiles (evidenced by 'list_profiles' and 'current_profile' sibling tools).
