Build MCPB

Build MCP servers end-to-end: scaffold from API docs, implement tools, validate the bundle, create an embedded skill resource, and release to the mpak registry. Supports Python (FastMCP) and TypeScript (@modelcontextprotocol/sdk).

Pipeline

Work through each phase in order. Read the linked workflow file for detailed instructions. Each phase has a gate that must pass before proceeding.

  • Phase 0 — Bootstrap: Language, service name, repo creation, template setup. Read [references/workflow/phase-0-bootstrap.md](references/workflow/phase-0-bootstrap.md)
  • Phase 1 — API Analysis: Fetch docs, identify resources, propose tools for approval. Read [references/workflow/phase-1-api-analysis.md](references/workflow/phase-1-api-analysis.md)
  • Phase 2 — Scaffold: Verify project structure from template. Read [references/workflow/phase-2-scaffold.md](references/workflow/phase-2-scaffold.md)
  • Phase 3 — Implement & Verify: Write tool logic, models, client; lint, typecheck, test. Read [references/workflow/phase-3-implement-and-verify.md](references/workflow/phase-3-implement-and-verify.md)
  • Phase 4 — Validate Bundle: Manifest, build, bundle, MTF scan, runtime. Read [references/workflow/phase-4-validate-bundle.md](references/workflow/phase-4-validate-bundle.md)
  • Phase 5 — Embed Skill: Create in-package skill resource, wire, verify. Read [references/workflow/phase-5-embed-skill.md](references/workflow/phase-5-embed-skill.md)
  • Phase 6 — Release: Commit, push, cut release, verify publication. Read [references/workflow/phase-6-release.md](references/workflow/phase-6-release.md)
