find_and_replace · LLM2Docs (Unofficial) MCP: Risk & Policy

WHAT IT DOES

What find_and_replace does on LLM2Docs (Unofficial)

AI agents use find_and_replace to create or update resources in LLM2Docs (Unofficial) — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LLM2Docs (Unofficial) environment.

WHY IT NEEDS A POLICY

Why find_and_replace needs a policy

This tool modifies document content by replacing existing text with new text. While it could cause significant unintended changes if misused (e.g., replacing common strings across the document), the operation is technically reversible (the original text could be restored), placing it in the Write category rather than Destructive.

Verdict

find_and_replace Rate-limited

find_and_replace 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.
