Verdicts

Commerce Layer API + MCP

Public OpenAPI 3.0 file and llms.txt. No price between the free plan and a sales-quoted Enterprise contract.

Snipcart API + MCP

Hosted MCP server with 38 documented tools and a self-hostable Bun build. No server-side cart or checkout. Orders only come from the browser widget.

Before you call either

Commerce Layer API + MCP

  1. Call get_resource_schema before any write. Preflight rejects bad filter shapes before they reach the API
  2. Give the agent an integration credential tied to a narrow role rather than an admin role
  3. On a 429, wait out the sliding window. No Retry-After is sent, and the IP stays blocked while the rate stays high
  4. Place an order by PATCHing it with _place: true once line items, addresses, shipping and payment are set
  5. Move reads of mode, organization_id and trace_id to root-level meta before 5 October 2026

Snipcart API + MCP

  1. Use the agent for back-office jobs (orders, refunds, discounts, stock, abandoned carts), not for placing orders
  2. Start with a test-mode key (ST_ prefix) before switching to live (SL_)
  3. Send the key in X-Snipcart-Api-Key. OAuth-only clients can't connect
  4. Stay under 100 MCP requests a minute and 10 in flight per key
  5. Ignore unknown response fields. Snipcart adds fields without a new version

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
