Buildkite Release notes and new features

Catch pipeline YAML errors before your first build with Buildkite MCP

Your AI agent can now check the pipeline YAML it writes before you commit or upload it. The Buildkite MCP Server includes validate_pipeline , a read-only tool that checks YAML syntax and structure against Buildkite's pipeline schema, without uploading the pipeline or starting a build.

• Catch pipeline YAML errors before your first build with Buildkite MCP
• Keep your focus on failures within group steps on the build canvas
• Retry jobs with narrower API token permissions
