get_artifact
Get detailed information about a specific artifact including its metadata, file size, SHA-1 hash, and download URL
get_build
Get build information including job IDs, names, and states. Use job_state to filter (e.g. 'failed,broken'). Returns enough detail to identify which jobs to investigate with log and artifact tools
get_build_test_engine_runs
Get test engine runs data for a specific build in Buildkite. This can be used to look up Test Runs.
get_cluster
Get detailed information about a specific cluster including its name, description, default queue, and configuration
get_cluster_queue
Get detailed information about a specific queue including its key, description, dispatch status, and hosted agent configuration
get_failed_executions
Get failed test executions for a specific test run in Buildkite Test Engine. Optionally get the expanded failure details such as full error messages and stack traces.
get_pipeline
Get detailed information about a specific pipeline including its configuration, steps, environment variables, and build statistics
get_test
Get a specific test in Buildkite Test Engine. This provides additional metadata for failed test executions
get_test_run
Get a specific test run in Buildkite Test Engine
list_annotations
List all annotations for a build, including their context, style (success/info/warning/error), rendered HTML content, and creation timestamps
list_artifacts_for_build
List all artifacts for a build across all jobs, including file details, paths, sizes, MIME types, and download URLs
list_artifacts_for_job
List all artifacts for an individual job, including file details, paths, sizes, MIME types, and download URLs
list_builds
List builds for a pipeline or across all pipelines in an organization. When pipeline_slug is omitted, lists builds across all pipelines in the organization
list_cluster_queues
List all queues in a cluster with their keys, descriptions, dispatch status, and agent configuration
list_clusters
List all clusters in an organization with their names, descriptions, default queues, and creation details
list_pipelines
List all pipelines in an organization with their basic details, build counts, and current status
list_test_runs
List all test runs for a test suite in Buildkite Test Engine
pause_cluster_queue_dispatch
Pause dispatch on a cluster queue, preventing new jobs from being dispatched to agents
read_logs
Read log entries from the file, optionally starting from a specific row number. ALWAYS use 'limit' parameter to avoid excessive tokens. For recent failures, use 'tail_logs' instead. Recommended limits: investigation (100-500), exploration (use seek + small limits). The json format: {ts: timestamp_ms, c: content, rn: row_number}.
resume_cluster_queue_dispatch
Resume dispatch on a paused cluster queue, allowing jobs to be dispatched to agents again
search_logs
Search log entries using regex patterns with optional context lines. For recent failures, try 'tail_logs' first, then use search_logs with patterns like 'error|failed|exception' and limit: 10-20. The json format: {ts: timestamp_ms, c: content, rn: row_number}.
tail_logs
Show the last N entries from the log file. RECOMMENDED for failure diagnosis - most build failures appear in the final log entries. More token-efficient than read_logs for recent issues. The json format: {ts: timestamp_ms, c: content, rn: row_number}.
unblock_job
Unblock a blocked job in a Buildkite build to allow it to continue execution
update_cluster
Update an existing cluster's name, description, emoji, color, or default queue
update_cluster_queue
Update an existing cluster queue's description or retry agent affinity
update_pipeline
Modify an existing Buildkite pipeline's configuration, repository, settings, or metadata
user_token_organization
Get the organization associated with the user token used for this request
