git_create_branch · LocalAnt MCP: Risk & Policy

WHAT IT DOES

What git_create_branch does on LocalAnt

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

WHY IT NEEDS A POLICY

Why git_create_branch needs a policy

Creating a git branch is a write operation that modifies repository metadata reversibly. The branch can be deleted or reset if needed, making it Write rather than Destructive. Severity is medium because miscreation of branches could disrupt development workflows, but the impact is contained to local/remote branch namespace and is easily recoverable.

From the tool's definition Tool name 'git_create_branch' and description 'Create and checkout a new branch' indicate creation of a new git branch, which modifies the repository state.

git_create_branch Rate-limited

git_create_branch 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.
