push_changes · Overleaf MCP Server MCP: Risk & Policy

WHAT IT DOES

What push_changes does on Overleaf MCP Server

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

WHY IT NEEDS A POLICY

Why push_changes needs a policy

The tool commits and pushes changes to Overleaf, which creates new git commits and updates the remote repository state. This is a reversible modification (changes can be reverted via git operations), not a destructive deletion or irreversible action. It does not execute arbitrary code, delete data, or involve financial transactions.

From the tool's definition Tool name is 'push_changes' with description 'Commit and push changes to Overleaf' — this modifies project state by committing and pushing code changes to a remote repository.

push_changes Rate-limited

push_changes 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.
