insert_footer · LLM2Docs (Unofficial) MCP: Risk & Policy

WHAT IT DOES

What insert_footer does on LLM2Docs (Unofficial)

AI agents use insert_footer 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 insert_footer needs a policy

The tool modifies document content by inserting a footer, which is a Write operation (creates/modifies data reversibly). Severity is medium because unauthorized footer insertion could inject misleading content, headers/footers, or metadata into shared documents, affecting document integrity and trust — but the action remains reversible via deletion.

From the tool's definition Tool name is 'insert_footer' and description states 'Insert a footer in the document' — this directly creates/modifies document structure by adding a footer, which is a reversible modification.
