resolve_comment · Overleaf MCP: Risk & Policy

WHAT IT DOES

What resolve_comment does on Overleaf

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

WHY IT NEEDS A POLICY

Why resolve_comment needs a policy

This tool creates or modifies data reversibly by updating the status of a comment thread. The action can be undone (comments can be re-opened), so it is not Destructive. It does not delete data, execute arbitrary code, or incur financial obligations. The impact is contained to comment thread state within a single project, justifying medium severity rather than high.

From the tool's definition 'Marks a thread as resolved' — modifies the state of a comment thread in the Overleaf project, a reversible operation that changes metadata.

Verdict

resolve_comment Rate-limited

resolve_comment 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.
