createLocalCommit · GitHub MCP Server MCP: Risk & Policy

WHAT IT DOES

What createLocalCommit does on GitHub MCP Server

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

WHY IT NEEDS A POLICY

Why createLocalCommit needs a policy

This tool creates commits, which are write operations that modify repository state. Commits are reversible through Git operations (revert, reset, amend), distinguishing this from Destructive actions. The blast radius is medium—a malicious agent could create unwanted commits that pollute history or introduce false attribution, but this doesn't destroy data or execute arbitrary code.

From the tool's definition Tool name 'createLocalCommit' and description 'Create a local Git commit' indicate creation of a commit object, which modifies repository state (the commit history/staging area) in a reversible manner through standard Git operations.
