Common questions

Is KlickyMart safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 12 days ago, and the latest version (2026.10.31) reached the registry 15 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

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.
