log_time · Redmine MCP Server MCP: Risk & Policy

WHAT IT DOES

What log_time does on Redmine MCP Server

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

WHY IT NEEDS A POLICY

Why log_time needs a policy

Logging time creates a new time entry (Write operation). It is reversible in principle (entries can be deleted or edited), so it does not reach Destructive. Misuse could result in inaccurate project billing or reporting, giving it medium severity.

From the tool's definition 'Log time spent on an issue or project' — creates a new time entry record in Redmine

Verdict

log_time Rate-limited

log_time 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.
