log · MCP Notes MCP: Risk & Policy

WHAT IT DOES

What log does on MCP Notes

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

WHY IT NEEDS A POLICY

Why log needs a policy

The tool creates or updates log entries for the current day, which is a reversible write operation typical of note-taking systems. No data is deleted, executed, or financial in nature. The low severity reflects the limited blast radius—modifications are limited to personal notes with no external system effects.

From the tool's definition Tool name 'log' with description 'Create or update today' indicates modifying/appending to daily log entries. Context as personal note-taking system confirms this is data creation/modification.

Verdict

log Rate-limited

log 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.
