Public MCP server for AI agents

What you can do with it

• Search and recommend CrowCrowCrow products inside a chat assistant.
• Compare two products and surface ratings, prices, and key features.
• Read blog posts and CMS pages (about, shipping, returns…) without scraping.
• Build a shopping agent that links the user back to the PDP for checkout.

Tools

All tools are documented in the live WebMCP descriptor and the OpenAPI spec. Capable MCP clients also auto-load three resource documents (ccc://guide/readme, ccc://schema/product, ccc://guide/categories) so the agent has the schema before it calls a tool.

Limits (anti-scraping)

The MCP exists to make our catalogue discoverable, not harvestable. Every anonymous request is bounded:

When a rate limit is hit you get an HTTP 429 with a Retry-After header and a JSON-RPC error message. Need higher caps for a partner integration? Email support@crowcrowcrow.com for a Bearer token.

Connect from Claude Desktop / Cursor

Add the snippet below to your claude_desktop_config.json (Claude Desktop) or your Cursor MCP settings. It uses the official mcp-remote bridge so HTTP MCP servers appear as if they were local.

{
  "mcpServers": {
    "crowcrowcrow": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://crowcrowcrow.com/api/mcp/mcp"]
    }
  }
}

Connect from Claude.ai (web) / ChatGPT custom connectors

Both clients accept a remote MCP URL directly. Paste https://crowcrowcrow.com/api/mcp/mcp into their Add Connector / Add MCP server dialog. Auth: None.

Response shape (summary)

products.search and products.list return compact summaries:

{
  "slug": "earth-mama-vegan-nipple-butter-2-pack",
  "sku": "AMZ-...",
  "asin": "B0...",
  "url": "https://crowcrowcrow.com/p/<slug>/<sku>",

FAQ

Do I need an API key?

No. The MCP is anonymous. Just rate-limited.

Can I use this to scrape your full catalogue?

Not really — the offset cap of 200 per query limits how deep you can paginate, and the rate limit will cut you off long before you finish. The MCP exists for agentic discovery, not bulk export. For bulk feeds use Google Merchant XML or contact us for partner access.

Are the prices accurate?

Yes. The MCP runs the same USD→INR conversion the storefront UI uses (live rate from currency_rates), so values match what a human visitor sees on the PDP.

Are there write operations?

No. The public MCP is strictly read-only — there is no way to place orders, modify the catalogue, or sign up users through it. Checkout happens on the storefront with browser session auth + Razorpay.

How do I report a bug or request a tool?

Email support@crowcrowcrow.com with the request payload, the response, and what you expected. We publish changes via /.well-known/webmcp.json.
