set_note_content · Pinako AI Bridge MCP: Risk & Policy

WHAT IT DOES

What set_note_content does on Pinako AI Bridge

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

WHY IT NEEDS A POLICY

Why set_note_content needs a policy

This tool modifies note content within the Pinako extension's data store. It does not create new data (Write rather than Execute), nor does it delete or overwrite irreversibly (not Destructive). The update operation is reversible—content can be changed again or restored.

From the tool's definition 'Updates an existing note' - the verb 'updates' indicates modification of existing data (the note's content). This is a reversible change to user data stored in the Pinako library/note system.

set_note_content Rate-limited

set_note_content 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.
