WHAT IT DOES

What user-profile does on IMCP - Insecure Model Context Protocol

AI agents use user-profile to create or update resources in IMCP - Insecure Model Context Protocol — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your IMCP - Insecure Model Context Protocol environment.

WHY IT NEEDS A POLICY

Why user-profile needs a policy

The word 'manage' typically encompasses creating, reading, updating, and potentially deleting profile settings. The most severe applicable category for profile management (excluding destructive deletion, which is not explicitly mentioned) is Write. Given this is part of IMCP, a deliberately vulnerable framework, there is elevated risk of misuse such as privilege escalation or unauthorized profile modification.

From the tool's definition 'Manage your user profile and preferences' — 'manage' implies both read and write operations on profile data

user-profile Rate-limited

user-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.
