Connect GitHub

One connection that reads GitHub: repositories, code, commits, pull requests, issues, releases and Actions — including the job logs that say why the deploy failed. The narrowing that matters is the token's repository scope.

Setting this up with your own agent? Give it these instructions.

Why there is one profile and not three

There used to be github/actions-read, github/code-read and github/triage-read. Choosing between them meant deciding, at connection time, which third of GitHub an agent would ever need — and during an incident the honest answer is "I do not know yet".

Someone debugging a failed deploy needs the workflow run, the job log that says what broke, the commit that triggered it, the file that commit changed and the pull request it arrived in. That is all three profiles. Expressing it as three connections meant three tokens, three audit trails and three chances to bind the wrong one.

So there is one connection that reads GitHub. The narrowing that matters is the token, and it is a better fence than the split ever was: a fine-grained token names its repositories, and the gateway cannot widen that.

Step 1 — mint the token

  1. Settings → Developer settings → Personal access tokens → Fine-grained tokens → Generate new token.
  2. Resource owner: the organisation, not your personal account, if the repositories belong to one.
  3. Repository access → Only select repositories, and pick exactly the ones this connection should reach.
  4. Permissions, all on Read-only:
PermissionWhy
Contentsfiles, commits, branches, releases
Metadatarequired; repository basics
Pull requestsPRs, files, reviews, status
Issuesissues and comments
Actionsworkflow runs, jobs and logs
  1. Leave Secret scanning alerts and Code scanning alerts at No access.
  2. Set an expiry. Generate. Copy it.

Step 2 — connect it

Services → Add a service, pick github/read-only. The upstream is GitHub's hosted MCP server and is filled in for you:

Credentialthe fine-grained token

Name it for what it reaches — ejd-github — because the name is the namespace an agent sees.

The two judgement calls worth knowing about

Job logs are allowed. get_job_logs is classified read_leaks, honestly: a build log contains whatever the build printed, and builds print more than they should. It is allowed anyway, because "why did the deploy fail" is unanswerable without it — and a denied log just means somebody opens the GitHub UI and reads the same thing unaudited. The leak is stated rather than hidden, and [principle 13](../reference/egress.md) keeps that output away from an AI.

Secret scanning alerts are denied, and always will be. That endpoint returns the leaked credential itself. There is no scoping that makes handing an agent your committed secrets acceptable, so it is not a setting.

Artifact downloads are denied too: an artifact is an arbitrary blob — a built image, a tarball of the workspace — and that is a download, not a diagnostic. list_workflow_run_artifacts says what exists and get_job_logs says what happened.

Checking the token really cannot write


# Should succeed: reading
curl -sS -H "Authorization: Bearer $GH_TOKEN" \
https://api.github.com/repos/OWNER/REPO/actions/runs?per_page=1 | head -c 200

# Should FAIL with 403: creating an issue
curl -sS -o /dev/null -w '%{http_code}\n' -X POST \
-H "Authorization: Bearer $GH_TOKEN" \
-d '{"title":"prodpeek-permission-test"}' \
https://api.github.com/repos/OWNER/REPO/issues

# Should FAIL with 403: secret scanning
curl -sS -o /dev/null -w '%{http_code}\n' \
-H "Authorization: Bearer $GH_TOKEN" \
https://api.github.com/repos/OWNER/REPO/secret-scanning/alerts

Two 403s and a 200 is what a correctly minted token looks like.
