Quick Start

Connect your agent in 4 steps — with merchant trust verification

Verified merchants17 MCP tools9 payment protocols

Pick the right endpoint (3 buckets)

Trusteed exposes three specialized endpoints per store. Start with Discovery — it is anonymous and cacheable, saving auth round-trips during exploration.

BucketEndpointWhen to useAuth
Discovery/{slug}/mcp/discoveryAnonymous exploration: catalog, search, trust, policies (14 tools)None
Customer/{slug}/mcp/customerCustomer context: orders, returns, profile (9 tools)OAuth 2.1 + RFC 8707 (resource=customer-mcp)
Checkout/{slug}/mcp/checkoutTransactional ops: cart, shipping, payment (19 tools)AgenticTrust JWT + Idempotency-Key + mandate

Legacy /{slug}/mcp deprecated — sunset via MCP_LEGACY_SUNSET. Migration guide.

1

Add the MCP server

Configure the MCP server URL in your Claude client or app. Replace {slug} with the store slug. No key? Use demo-store (read-only, no auth).

{
  "mcpServers": {
    "trusteed": {
      "url": "https://trusteed.xyz/{slug}/mcp",
      "headers": {
        "X-Agent-Api-Key": "agnt_your_key"
      }
    }
  }
}

Search products

Use search_products to explore catalogs. Filter by category, price, availability. Also available: browse_categories, compare_products, nlweb_ask (semantic search).

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "search_products",
    "arguments": {
      "query": "laptop",
      "max_price": 2000,
      "in_stock_only": true,
      "limit": 5
    }
  }
}

Verify merchant trust

Before purchasing, check the trust score and verification level. Only proceed if trustScore ≥ 0.70.

// get_merchant_profile → identity verification
// Current stores return "STANDARD" or "BASIC" verification levels.
{
  "trust_score": 0.91,
  "verification_level": "STANDARD",
  "policies": {
    "return_window_days": 30,
    "free_shipping_threshold": 75
  }
}

Trust score thresholds: • ≥ 0.95 — ELITE: maximum trust, proceed without friction • ≥ 0.85 — VERIFIED: verified merchant, proceed with standard confirmation • ≥ 0.70 — STANDARD: minimum eligible, proceed with standard confirmation • < 0.70 — Do not initiate checkout Full methodology: /api/v1/trust/methodology
