WHAT IT DOES

What maintainer_can_modify does on GitHub

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

RISK

Why maintainer_can_modify is rated Medium

This tool writes/modifies configuration settings for pull requests (likely enabling or disabling maintainer edit permissions), which is reversible and non-destructive. It changes pull request state but does not delete data or execute arbitrary code. Severity is medium because granting unintended edit permissions could allow unauthorized modifications to code or PR metadata, affecting repository integrity.

From the tool's definition Tool name 'maintainer_can_modify' and description 'Allow maintainer edits (boolean, optional)' indicate this modifies pull request permissions/settings to enable maintainers to edit PR content or metadata.
