WHAT IT DOES

What log_time does on Redmine

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

WHY IT NEEDS A POLICY

Why log_time needs a policy

Based on the server description mentioning 'time logging' as a key feature and the tool name 'log_time', this tool almost certainly creates a new time log entry in Redmine. This is a Write operation (creating data reversibly). Severity is medium since misuse could result in incorrect time entries being logged, but entries can typically be corrected. Confidence is reduced due to the empty tool description.

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.

FAQ

Questions about log_time

What does the log_time tool do? +

log_time. It is categorised as a Write tool in the Redmine MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on log_time? +

Register the Redmine MCP server in PolicyLayer and add a rule for log_time: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Redmine. Nothing to install.

What risk level is log_time? +

log_time is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit log_time? +

Yes. Add a rate_limit block to the log_time rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block log_time completely? +

Set action: deny in the PolicyLayer policy for log_time. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides log_time? +

log_time is provided by the Redmine MCP server (xukaaaa/redmine-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
