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: [email protected]

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
