PurchaseIQ MCP Server

Pre-purchase trust intelligence for AI agents. One tool call before checkout: product recalls (46,000+ records across US/EU/CA/FR), seller credibility, scam and phishing signals, and an AI trust verdict, aggregated from 15+ verified sources.

This repository hosts the MCP Registry manifest for the hosted PurchaseIQ server. The server itself is remote — there is nothing to install or run.

Endpoint

https://purchaseiq.io/api/mcp

Transport: Streamable HTTP (stateless JSON-RPC over POST). Registry name: io.purchaseiq/mcp.

Connect

Claude Code

claude mcp add --transport http purchaseiq https://purchaseiq.io/api/mcp

Cline (VS Code) — add to cline_mcp_settings.json (Cline panel → MCP Servers → Configure MCP Servers). The "type" field is required: without it Cline defaults to the legacy SSE transport, and this server is POST-only streamable HTTP, so the connection fails with a 405.

{
  "mcpServers": {
    "purchaseiq": {
      "type": "streamableHttp",
      "url": "https://purchaseiq.io/api/mcp"
    }
  }
}

Then reload the window (Command Palette → Developer: Reload Window). Step-by-step agent instructions: llms-install.md.

Cursor, Claude Desktop & other MCP clients — add to your MCP config (mcp.json / claude_desktop_config.json):

{
  "mcpServers": {
    "purchaseiq": {
      "url": "https://purchaseiq.io/api/mcp"
    }
  }
}

Claude.ai — Settings → Connectors → Add custom connector → paste the endpoint URL.

ChatGPT — Settings → Connectors → Create (developer mode) → paste the endpoint URL.

The tool: analyze_purchase

Pass whatever the agent has — all inputs optional, at least one required:

Response is a compact agent verdict:

{
  "verdict": "caution",
  "score": 55,
  "topFlags": [
    "Domain registered 3 months ago",
    "No company registration found",
    "SSL valid, TLS 1.3"
  ],
  "reason": "Very new domain with no verifiable company behind it."
}

verdict is proceed, caution, or avoid. score is 0–100. topFlags lists up to three highest-priority signals, dangers first.
