What is Buildkite?
Buildkite ships Agent v4, a VS Code extension, and MCP write-access to secrets in the same week
Buildkite is expanding on three fronts simultaneously. Agent v4 — the first major version since 2018 — is now the stable release, clearing eight years of deprecated behavior. The MCP server gained cluster secret creation, test-suite attribution, and build-failure summaries. And a VS Code extension now surfaces pipelines, live job logs, agent status, and YAML validation without leaving the editor.
What is FireHydrant?
On-call overrides now survive a schedule edit — and are the only way to change a shift.
FireHydrant shipped a real override layer for on-call schedules. Overrides now survive schedule edits made from either the web UI or the API, always win against an overlapping generated shift, can be stacked, and can be cancelled to restore the original system-generated shift. Reassignment, coverage requests, and shift deletion no longer mutate the generated schedule at all — each creates an override instead, which is what makes every change cleanly undoable. The constraint is historical: restoring a shift requires knowing what it originally looked like, and that data has only been tracked since 24 July 2026, so older rotations need a one-time regeneration first.

Buildkite ships Agent v4, a VS Code extension, and MCP write-access to secrets in the same week
◆ Current state
Buildkite is expanding on three fronts simultaneously. Agent v4 — the first major version since 2018 — is now the stable release, clearing eight years of deprecated behavior. The MCP server gained cluster secret creation, test-suite attribution, and build-failure summaries. And a VS Code extension now surfaces pipelines, live job logs, agent status, and YAML validation without leaving the editor.
◆ Where it's heading
Two threads are running in parallel: hardening the core agent (v4, ephemeral job acquisition tokens, 1 GiB log quota) and expanding the agentic surface (MCP tools for secrets, test attribution, step uploads, failure summaries). The VS Code extension opens a third front — IDE-native CI — that no major CI platform currently owns. The combination points toward Buildkite positioning as infrastructure for AI-driven developer workflows, not just pipeline execution.
◆ Prediction
The MCP server will keep acquiring write operations — secret creation is already there, pipeline modification is the next logical step. The VS Code extension will likely gain pipeline creation and editing to close the IDE-native CI loop.

On-call overrides now survive a schedule edit — and are the only way to change a shift.
◆ Current state
FireHydrant shipped a real override layer for on-call schedules. Overrides now survive schedule edits made from either the web UI or the API, always win against an overlapping generated shift, can be stacked, and can be cancelled to restore the original system-generated shift. Reassignment, coverage requests, and shift deletion no longer mutate the generated schedule at all — each creates an override instead, which is what makes every change cleanly undoable. The constraint is historical: restoring a shift requires knowing what it originally looked like, and that data has only been tracked since 24 July 2026, so older rotations need a one-time regeneration first.
◆ Where it's heading
The last year reads as one project — making an incumbent-grade on-call product safe enough to switch to. Customizable retrospective exports, authenticated status pages, consolidated analytics, an EU instance, MS Teams support, then the Signals Migrator that automates the move off PagerDuty and Opsgenie. Overrides fit the same pattern: a feature teams assume already exists, previously broken badly enough that admins learned not to touch a schedule once coverage was arranged. The work is closing table-stakes gaps ahead of a migration window, not opening new surfaces.
◆ Prediction
Expect the override model to be pushed out to the API and Terraform surfaces next, along with prompts to regenerate stale rotations before Opsgenie's April 2027 deletion date drives migration volume.
