acp-checkout-mcp SKILL.md skillA
acp-checkout-mcp from orcaqubits/agentic-commerce-skills-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add orcaqubits/agentic-commerce-skills-plugins/acp-checkout-mcp@git:20260914.08f85a3Pins git:20260914.08f85a3 in mdr.lock. Pin the fingerprint instead.

Implement ACP checkout as an MCP server, exposing checkout operations as MCP tools. Use when building an MCP-based commerce server for AI agents that use tool-calling to complete purchases.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ACP Checkout — MCP Binding ## Before writing code **Fetch live docs**: 1. Fetch `https://github.com/agentic-commerce-protocol/agentic-commerce-protocol/releases` for the current spec version. 2. **Fetch the official OpenRPC document** — `spec/<version>/openrpc/openrpc.agentic_checkout.json` in the repo. Since the `2026-04-17` release there is a machine-readable JSON-RPC description of the checkout binding; **use it rather than hand-deriving tool names**. The table below predates it. 3. Fetch `https://developers.openai.com/commerce/specs/checkout/` for checkout operation semantics. 4. Fetch `https://modelcontextprotocol.io/specification/` — it redirects to the current MCP revision. Confirm the transport model before writing server code; MCP's core changed shape between revisions (the stateless core removed the `initialize` handshake and `Mcp-Session-Id`), so a server written against an older revision will not match a current client. 5. Fetch MCP SDK docs: web-search `site:github.com modelcontextprotocol python-sdk` or `typescript-sdk` for the current SDK. ## Conceptual Architecture ### What MCP Binding Means …

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/acp-checkout-mcp@sha256:3abb47a0ef68c81cThe line at the top of this page pins the label git:20260914.08f85a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
