A self-hosted service that answers "what happened in CI" — over MCP, REST and a CLI.

It reads GitHub Actions runs, jobs, steps and logs; it does not poll in the background, does not keep a central token pool, and never treats a cached run as the truth when GitHub can still answer.

⁠What you get

Ask once, in any protocolci_status, find_runs, get_run, get_job, get_job_log, search_job_log, get_run_failed_logs, wait_for_run, trigger_workflow — over MCP (Streamable HTTP), REST and a CLI. One flow, three shapes; a model or a script uses the same answers.
Three layers, one step eachget_run names the job that failed, get_job names the step, get_job_log returns its text. No call answers two layers, so no caller has to know which one it is looking at. A failed job read without a scope starts at its failed steps; whole_job=true asks for everything.
One failure in twelve jobs, one groupget_run_failed_logs groups a run's failed-step texts by byte equality: one copy plus the jobs that printed it. Same cause or twelve? One call, and no judgement about meaning.
Step-level logs, keptGitHub splits a run into per-step files for about an hour; after that the same endpoint returns one merged document. The service captures the split while it exists, stores it as ordinary rows, and reads it forever. Missed capture is reported honestly — never replaced by another step's text.
Windows that address, not interprettail, an explicit line range, or your own regex. search_job_log shows context for the last matches by default, because a log ends with its conclusion; every position is still reported. No guessing at test summaries or teardown output, because a general tracker cannot know what any project prints.
Trigger and wait, without burning minutestrigger_workflow dispatches on request; if_absent=true answers "this commit already ran" without starting a second run. rerun_run(failed_only=true) repeats only the jobs that broke, after a local check that there are failed jobs. wait_for_run is a bounded long poll whose timeout comes from the workflow's own history.
PostgreSQL, and it says soLog tables are partitioned by month so old data is one DROP TABLE; a trigram index accelerates searching them (pg_trgm, ~1× the log text in disk); the schema is the service's own renderer; the test suite runs against a real server.
A budget from real time, not the queueEvery run read carries timings: the jobs' span, the queue, and the span of the jobs that passed — the numbers a wait is sized from, so a queue behind other repositories does not inflate the p50/p90. db usage and ci_status.storage report what the database actually holds.
One image, two registriesimages.yml publishes the same multi-arch build to Aliyun (vistart_public/github-actions-tracker) and Docker Hub (vistart/github-actions-tracker), tagged latest. Each destination has its own secrets, so either can be absent. It runs only when asked for, and build.revision — not a tag — says which build is running.
Metrics in the standard formatGET /metrics on the REST listener answers with the Prometheus text format: webhook deliveries, GitHub calls by status code, tool calls by outcome, connection-pool gauges via ci_status.health. Process-local counters; sum across instances in the scraper.

⁠Why you would use it

Three different things, and the third is the easiest to underestimate.

  • Context: a 4,000-line job log becomes grep and a few lines of context; a 12-job matrix becomes a 12-line roster. Some of that log does not fit in a context window at all, so the choice is not cheaper but possible.
  • Time: wait_for_run is one bounded call instead of a polling loop; cancel_run and if_absent=true stop minutes you would otherwise spend, and trigger_workflow returns p50/p90 so you can decide what to wait for.
  • Wrong conclusions: attempt/is_latest separates a capacity blip from a broken backend; has_log plus reason separates "no output" from "nothing was captured"; ci_status.health.alerts reports its own silent degradation as an executable list.

For the long version — including an operator's measured session and what we saw using the service on itself — see What it saves⁠.

⁠The advantage of a local cache

Once a log is stored, reading it is a local query — and a local query is cheap, repeatable, and parallel:

  • Filters are local. find_runs narrows by commit, pull request, branch, workflow file or status against stored rows; recent_runs answers for sixteen repositories in one call. None of that spends GitHub quota.
  • The text is local too. Windows, grep and search run against one stored document, so partial reads are the normal case rather than an exception.
  • The pattern is yours. Failure, error, warning, or a test conclusion — the service returns the lines a caller's pattern matched and their line numbers. Switch test frameworks and one string changes; the tracker does not need to relearn what your output means.
  • The database carries the load. A read is one query, not a poll: no background jobs, no queue, and PostgreSQL's parallel reads and cascades absorb whatever the filter admits.

⁠Use it from your coding agent

The MCP endpoint is http://127.0.0.1:8001/mcp (Streamable HTTP). One line per agent — the full configuration reference, including the shared-file shapes and what each agent's approval gate does, is Coding agents over MCP⁠:

claude mcp add --transport http github-actions-tracker http://127.0.0.1:8001/mcp   # Claude Code
codex mcp add github-actions-tracker --url http://127.0.0.1:8001/mcp               # Codex (TOML)
opencode:  "mcp": { "github-actions-tracker": { "type": "remote", "url": "…", "oauth": false } }   # opencode.json
cmd mcp add --transport http github-actions-tracker http://127.0.0.1:8001/mcp      # Command Code

With GHAT_API_KEY set, add --header "Authorization: Bearer <key>" (Claude Code, Command Code), bearer_token_env_var (Codex) or an Authorization header with oauth: false (OpenCode).
