github-official@r5
VERIFIED· install onlyVerified PublisherPublisher claims: "Official GitHub MCP Server, by GitHub. Provides seamless integration with GitHub APIs, enabling advanced automation and interaction capabilities for developers and tools." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.
Before you give it your token
- It will ask for
GITHUB_MCP_SERVER_E2E_TOKENConfiguration, not credentials: APP, DEV, DISPLAY, GITHUB_MCP_SERVER_E2E_DEBUG, GITHUB_MCP_SERVER_E2E_HOST, WAYLAND_DISPLAY- Where it talks to
- no vendor host named in the codeAlso ghe.com, primer.style, githubusercontent.com, uploads.hostname, raw.hostname, mycompanygithub.com, notgithub.com, myghe.com — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- use of the skill by an agent
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names ghe.com, primer.style, githubusercontent.com, uploads.hostname, raw.hostname, mycompanygithub.com, notgithub.com, myghe.com as well as its own vendor. The guard injects GITHUB_MCP_SERVER_E2E_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.
Is github-official@r5 safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-10 and scored it 91/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. The publisher is verified. Summary: no network, touches nothing outside the project, writes no memory.
