@part-kit/mcp

MCP server for the PartKit registry — verified, attested standard parts for AI coding agents. Agents use it to discover parts, resolve capability requests into deterministic install plans, and read contracts, seams, and attestations.

Tools

| Tool | Purpose | |---|---| | search_parts | Catalog search (empty query lists everything) | | resolve_plan | Capabilities + parts.lock → topologically-ordered install plan | | get_contract | Machine-readable contract for a part | | get_seams | What the app must implement — sufficient without reading src/ | | get_attestation | Signed verification record with freshness | | get_upgrade_plan | Seam changes between versions | | inspect_repo | This repo's installed parts: versions, vendor swaps, drift, the capability graph | | doctor_repo | Does this repo's wired app work — routes mounted, env valid, seams provided | | provision_repo | The ordered vendor setup left, with {ENV} placeholders substituted | | conform_repo | Did the build match parts.spec.json — every capability from a verified part, on-vendor, nothing hand-rolled | | scaffold_app | Start a new verified backend (the MCP twin of create-partkit-app) |

Usage

No setup required — the server talks to the live hosted registry by default:

{
  "mcpServers": {
    "partkit": {
      "command": "npx",
      "args": ["-y", "@part-kit/mcp"]
    }
  }
}

The default registry is https://registry.partkit.dev (live). To point at a different one — a local checkout or a private registry — pass --registry <path-or-url> or set the PARTKIT_REGISTRY env var.
