Pinchy — MCP Server for Other

pinchy-mcp

· MCP Registry: com.trypinchy/pinchy · trypinchy.com

MCP server that finds coupon codes for any online store. Remote endpoint: https://mcp.trypinchy.com/mcp (Streamable HTTP, no auth).

Shopping in a browser yourself? The same codes, tried for you at checkout: Pinchy – Coupon Finder & Auto Apply for Chrome.

Connect

{ "mcpServers": { "pinchy": { "type": "http", "url": "https://mcp.trypinchy.com/mcp" } } }

Claude Code: claude mcp add --transport http pinchy https://mcp.trypinchy.com/mcp

Clients that only speak stdio can run the npm package instead:

{ "mcpServers": { "pinchy": { "command": "npx", "args": ["-y", "pinchy-mcp"] } } }

Tool

find_coupons({ store, limit? }) — store is a domain or any URL on the store; limit defaults to 10 (max 50). Returns { domain, storeName?, coupons: [{ code, description?, expiresAt?, successCount?, lastWorkedAt? }] }, ordered by how likely a code is to work. An unknown store returns an empty list.

Run it yourself

pnpm install
pnpm dev          # http://127.0.0.1:4020/mcp
pnpm test

Config is read from the environment, see .env.example. The process binds to 127.0.0.1 and trusts CF-Connecting-IP for rate limiting, so expose it only through a proxy that sets that header.

Privacy Policy

The server receives a store domain and nothing else: no account, no conversation content, no identifiers. Full policy: https://trypinchy.com/privacy.html · Contact: hi@trypinchy.com
