常见问题

KlickyMart 安全吗?

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(2026.10.31)于6天前进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

同一分类中有:Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

KlickyMart

KlickyMart is a public, signed map of online stores for software agents: whether an agent can reach a store, how checkout works, and which payment methods the store accepts, with attention to Bitcoin and privacy-respecting Bitcoin options. Records are published as Nostr events (see NIP-DRAFT.md). A FloppyKit project.

Status: draft. No crawl data is published in this repository yet.

Contents

  • NIP-DRAFT.md: draft event kinds for the directory and payment handshakes.
  • CRAWL-RUBRIC.md: record schema and grading rules (v0.3 draft changes at the end).
  • CASCADE.md: build plan.
  • crawler/: Playwright crawler (crawl.py), deterministic payment extractor (extract.py), terms-of-service checker (tos.py), signing helpers, tests.
  • crawler/KNOWN-LIMITATIONS.md: known limitations.
  • site/bot/index.html: the crawler info and opt-out page, served at https://klickymart.com/bot.
  • site/: KlickyMart web app (Worker, API, dashboard). See site/README.md.

Use it from an agent (MCP)

Agents should start at https://klickymart.com/llms.txt. MCP endpoint: https://klickymart.com/mcp. It uses a minimal, stateless Streamable HTTP transport: one JSON-RPC message per POST, answered with a single application/json body. It negotiates protocol versions 2024-11-05, 2025-03-26 or 2025-06-18 (tools only). There is no SSE stream and no session ID, and GET /mcp returns 405. Tools: search_merchants, get_record, check_domain. No key needed.

Claude Desktop (claude_desktop_config.json launches stdio servers, so this goes through the mcp-remote bridge, which needs Node.js):

{

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

Cursor (~/.cursor/mcp.json or .cursor/mcp.json):

{

"mcpServers": { "klickymart": { "url": "https://klickymart.com/mcp" } } }

Any Streamable HTTP client:

curl -s https://klickymart.com/mcp -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \\

-d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"check_domain","arguments":{"domain":"example.com"}}}'

Reviews: anyone can review a merchant with a signed kind 422 event (a tag 31420: : , rating, attempt, optional pay). Submit it with POST /reviews (?dry_run=1 validates without storing) or the MCP tool submit_review, and read reviews with GET /reviews?domain= or get_reviews. Agents should use a fresh keypair dedicated to KlickyMart for pseudonymity and must never send a secret key. Reviews are signed claims; we verify signatures and format, not the opinion. Full guide: /llms.txt and /about#reviews. Spec: NIP-DRAFT.md → "422 as a merchant review".

Plain HTTP: GET /check?domain=example.com answers "can my agent shop here?" from the index only. It never starts a live crawl.

Crawler guardrails

  • Honest user agent: FloppyKitMapBot/0.2 (+https://klickymart.com/bot). No stealth plugins or fingerprint changes, no proxies or IP rotation.
  • robots.txt is read first; an error, 401, 403 or timeout means the whole site is treated as disallowed.
  • If a site's terms ban automated access, the site is not crawled; only that finding is recorded, with a quote and URL.
  • Public pages only: no login, no accounts, no orders, no payment details, no form submits beyond add-to-cart, no captcha solving. Blocks are recorded as findings.
  • At least 2 s between requests, at most 10 pages per site.
  • Customer reviews, Q&A and comments are never used as evidence. Every payment method in a record carries a quote and a URL; unknowns stay null.

Opt out: add User-agent: FloppyKitMapBot / Disallow: / to robots.txt. Details: https://klickymart.com/bot

Run the tests

cd crawler python3 -m venv .venv && . .venv/bin/activate pip install -r requirements.txt && python -m playwright install chromium python -m unittest discover -s tests -v

The tests use synthetic fixtures and make no network requests.
