edit_message · Claudegram MCP: Risk & Policy

WHAT IT DOES

What edit_message does on Claudegram

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

WHY IT NEEDS A POLICY

Why edit_message needs a policy

Editing messages is a Write operation—it modifies data (message content) reversibly. The severity is medium because an AI agent could misuse this to alter message history, spread misinformation, or manipulate conversations, but the effect is bounded to the user's own account and messages can typically be recovered or undone.

From the tool's definition Tool name 'edit_message' and description 'Edit one's message' (translated from Russian) indicate modifying existing messages. This is a reversible operation that changes data without deleting it.

Verdict

edit_message Rate-limited

edit_message 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.
