universalcartmerchantgate-mcp — Claude Code MCP server
A hosted MCP server that checks whether a store is ready for Universal Cart, sorts out checkout blockers and exports the readiness log.
claude mcp add --transport http universalcartmerchantgate-mcp https://universalcartmerchantgate.clauxel.com/mcpWhat universalcartmerchantgate-mcp does
The endpoint is https://universalcartmerchantgate.clauxel.com/mcp, served over streamable HTTP. Five tools ship with it: check_universal_cart_readiness for store readiness, classify_checkout_blocker for sorting a checkout failure into a class, explain_offer_gap for gaps between offer and expectation, issue_agentic_commerce_receipt for a structured receipt, and export_readiness_log for the log. Tool output is structured, so it drops into a report or passes along an agent chain without cleanup.
Production calls need a bearer token. The public server card sits at https://universalcartmerchantgate.clauxel.com/server-card.json, and the registry name is com.clauxel.universalcartmerchantgate/universalcartmerchantgate-mcp. Get that token first. Without it your production requests simply fail, and you would be wiring the server into a config for nothing.
The repository holds documentation only — no production source, no payment configuration, no customer records. Commerce teams, merchant operations, marketplace owners and agentic checkout reviewers are the intended users.

- pin down what blocks a checkout
- explain a gap between an offer and what the buyer expects
- issue a structured receipt for an agentic purchase
- export the readiness log
Example prompts for the agent

- Classify why checkout is failing and name the blocker type
- Export the readiness log for the past week
