Analysis summary

GitHub MCP Server is an officially published MCP server from GitHub. Anomity scores its risk at 20 out of 100 (low).

GitHub's own MCP server, written in Go and maintained by the GitHub team. It exposes repositories, issues, pull requests, code search, and Actions to an agent as structured tools, so a coding assistant can triage an issue, read the diff on a PR, or search across an organisation's code without a human pasting context.

It authenticates as you. The server reaches the network and holds a GitHub token — which is the capability that matters, because the token's scopes define the blast radius, not the server's code. A token with `repo` write on an organisation lets any agent driving this server push branches, edit workflows, and comment as you. Issue and PR text is attacker-controlled on public repositories, so treat it as untrusted input reaching an agent that holds write credentials, and scope the token to the narrowest set of repositories that makes the assistant useful.

Capabilities

Every capability the entry declares, with the security implication of each.

  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.
  • credentials:access Credentials access
    Reads provider API keys, OAuth tokens, or other secrets from the host keychain or environment.
  • git:access Git access
    Reads or writes through git. Allows changes to commit history, branches, and remotes.
