What is Buildkite?
Buildkite is rebuilding its MCP server around what an agent actually does with a failed build.
Nearly every release in the last fortnight touches the MCP server. It now tracks the stateless MCP 2026-07-28 specification, bundles a multi-step failure investigation into a single get_build_failure_summary call, adds wait_for_build so agents stop hand-rolling polling loops, exposes discoverable skill guides, and trims job-list and log-search payloads for token cost. Alongside that, Agent v4 is dated for 1 September, GitLab merge-request builds arrive, and the Elastic CI Stack gains Ubuntu 24.04.
What is Jackett?
A daily-shipping indexer proxy whose entire product is a scraper definition file that never stops rotting.
Jackett ships a tagged release essentially every day, and every one of them is the same shape: tracker selectors updated, domains bumped, categories added, dead sites removed. The release notes are auto-generated commit lists with no prose. The C# application itself is stable; what changes is the YAML definition corpus that keeps a few hundred torrent trackers reachable through a single Torznab endpoint.

Buildkite is rebuilding its MCP server around what an agent actually does with a failed build.
◆ Current state
Nearly every release in the last fortnight touches the MCP server. It now tracks the stateless MCP 2026-07-28 specification, bundles a multi-step failure investigation into a single get_build_failure_summary call, adds wait_for_build so agents stop hand-rolling polling loops, exposes discoverable skill guides, and trims job-list and log-search payloads for token cost. Alongside that, Agent v4 is dated for 1 September, GitLab merge-request builds arrive, and the Elastic CI Stack gains Ubuntu 24.04.
◆ Where it's heading
The MCP work has moved past exposing endpoints to designing for the agent's workflow: fewer, fatter, bounded calls that answer a question rather than return data. Token efficiency is now treated as a product constraint — trimmed job listings, 40% smaller log-search responses, annotation summaries without bodies. Everything else on the roadmap is the unglamorous cutover work that keeps the platform current.
◆ Prediction
Expect more purpose-built composite tools in the same shape as get_build_failure_summary, and expect the 1 September v4 cutover to generate a run of compatibility fixes around the reversed hook order and the secrets-fail-the-upload default.
Jackett
5.0INFRA · APIS
A daily-shipping indexer proxy whose entire product is a scraper definition file that never stops rotting.
◆ Current state
Jackett ships a tagged release essentially every day, and every one of them is the same shape: tracker selectors updated, domains bumped, categories added, dead sites removed. The release notes are auto-generated commit lists with no prose. The C# application itself is stable; what changes is the YAML definition corpus that keeps a few hundred torrent trackers reachable through a single Torznab endpoint.
◆ Where it's heading
This is maintenance-as-product, and the cadence is a symptom rather than a sign of momentum: trackers move domains, add anti-bot checks, and change markup, so the definitions decay continuously and the fix rate has to match. The visible trend across these releases is attrition — torr9, rockbox, rain, runtheframes, torrentleech-pl and elitetorrent-wf all removed in a single fortnight — partially offset by category expansion on the trackers that survive.
◆ Prediction
Expect the daily definition-churn cadence to continue unchanged, with the removal list growing faster than the addition list. Nothing in these entries indicates work on the application core.
