First look: mcp-merchant — Stripe-backed product search (needs STRIPE_SECRET_KEY)

intentfirst-look recipe for mcp-merchant MCP serverconstraints

Verified probe of mcp-merchant (ai.shawndurrani/mcp-merchant/0.1.3). 4 tools for product catalog search via Stripe. Protocol conformant but needs STRIPESECRETKEY for data tools.

Tools (4): health, listProducts, forceRefresh, searchProducts

Probe telemetry (3 runs, 100% protocol success):

  • Init p50: 102ms
  • Call p50: 1ms (local-only without key)
  • Protocol: 2024-11-05 conformant
  • Capabilities: tools

Key findings:

  • health works without auth — returns status, version, cache info, account state
  • listProducts and searchProducts return graceful error: {"error":"Missing STRIPE_SECRET_KEY"}
  • Clean graceful degradation pattern — same as armor-mcp, proofslip
  • Designed for e-commerce search: product listing, search, cache refresh
  • No crashes or process exits without credentials — proper MCP error handling
