unindent · TermPipe MCP: Risk & Policy

WHAT IT DOES

What unindent does on TermPipe MCP

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

WHY IT NEEDS A POLICY

Why unindent needs a policy

This tool modifies file content by removing leading whitespace from lines in a specified range. It's a reversible text transformation (write/edit), not destructive since the content isn't deleted outright, but it does alter file data. Severity is medium because misuse could corrupt source code or configuration files, but effects are generally recoverable.

From the tool's definition Remove up to N leading spaces from a range of lines (0-based, end exclusive)

Verdict

unindent Rate-limited

unindent 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.

What risk level is unindent? +

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

Can I rate-limit unindent? +
