Formquote — MCP server

English · 中文

Ask an AI assistant “what does it cost to verify 25,000 emails?”, “which email verifier is cheapest for 300,000 addresses if I already have 5,000 Reoon credits?” or “can I use GT Cinetype on a site with 50,000 pageviews a month, and what would the licence cost?” — and get published prices from Formquote, each with the date it was checked, its source, and what is still unconfirmed.

https://formquote-mcp.chen-yu-d1.workers.dev/mcp

No account, no API key, no sign-in. Read-only. Streamable HTTP. Works in ChatGPT, Claude, Cursor, VS Code and any other MCP client.

What it covers

Formquote compares published prices and licence terms that it has checked by hand, with a source link and a date for each. It is a small catalogue, and the tools say so:

The prices are list prices observed on the dates shown, not live checkout quotes. Taxes and checkout fees are left unconfirmed unless the seller states them. Nothing can be ordered or paid through this server. Formquote’s PCB estimates need an operator key and are not part of it.

Tools

All four tools are read-only (readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: false).

goal is lowest_cash_now, lowest_job_cost or best_requirement_fit. lang (en, zh, ja, fr, de) picks the language of the Formquote page linked in the answer; notes recorded by Formquote stay in their original language (mostly Chinese), which chat models translate.

Every result has a short text answer and the same data as structuredContent. Input is checked before anything is sent: only counts and usage facts are accepted, never email addresses or files.

Any other client

• Clients that speak Streamable HTTP: point them at the URL above.
• Clients that only run local (stdio) servers: bridge with mcp-remote (examples/clients/stdio-bridge.json).
• Plain HTTP: examples/curl.sh.

curl -s https://formquote-mcp.chen-yu-d1.workers.dev/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'MCP-Protocol-Version: 2025-06-18' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"compare_email_verification_prices","arguments":{"emails":25000}}}'

The server speaks MCP 2026-07-28 (stateless, server/discover) and the earlier handshake versions (2025-11-25, 2025-06-18, 2025-03-26). There are no sessions; every request stands alone.

The API behind it

The server is a thin wrapper over Formquote’s public quote API, documented at pcba-quote-lab.pages.dev/en/developers (OpenAPI 3.1): GET /api/v2/catalog and POST /api/v2/quotes for the three public categories. It caches identical requests for a few minutes, times out slow calls, never answers a failed call from an older result, and keeps a shared ceiling on calls so a burst can’t overload the API.

Privacy

• The server keeps no logs and sets no cookies. It has no accounts and no sessions.
• Tool inputs are counts and usage facts (how many emails, which licence use). They are sent to the Formquote API to compute the answer and are not stored by this server; Formquote’s API does not persist digital quote bodies either (privacy).
• Anonymous counts. To see whether the connector is useful, it keeps daily totals with fixed labels only: the day, whether it was a connection, a tool list or a tool call, which tool and category, the outcome (ok, no match, invalid input, busy, upstream error) and the client family (ChatGPT, Claude, Cursor, VS Code, …, directory scanner, other). No IP address, no user or session id, no tool input, no User-Agent string, no time finer than the day. See src/counts.js and COUNTS.md.
• Seller links open the seller’s own site, where its terms and privacy policy apply.

Develop

npm install
npm test                 # unit tests with recorded API answers
npx wrangler dev         # http://localhost:8787/mcp
node scripts/smoke.mjs http://localhost:8787/mcp
npx -y @modelcontextprotocol/inspector --cli http://localhost:8787/mcp --transport http --method tools/list

Deploying needs the Cloudflare account that owns the Worker (npx wrangler deploy). To run your own copy, remove or replace the d1_databases entry in wrangler.jsonc; without it nothing is counted.

Licence

The server code and examples: MIT. The catalogue, prices and notes it returns come from Formquote’s API; prices belong to their sellers and change without notice.
