WHAT IT DOES

What github_set_homepage does on Github

AI agents use github_set_homepage 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 github_set_homepage is rated Medium

Setting a homepage URL is a Write operation—it creates or modifies repository metadata without deleting data or causing irreversible changes. The severity is medium because while the change is easily reversible and non-destructive, it affects public repository visibility and could be used to redirect users to malicious sites if an AI agent were compromised.

From the tool's definition The tool 'github_set_homepage' modifies repository metadata by setting the homepage URL displayed on the repo card, as stated in the description. This is a reversible modification to repository settings.

github_set_homepage Rate-limited

github_set_homepage 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.
