Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed. How it is computed.
| remote | auth | reachable | uptime 30d | p50 | protocol | last ok |
|---|---|---|---|---|---|---|
https://tracetail.io/mcp streamable-http | none | yes | 93% | 415 ms | 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26 | 2026-10-20 |
check_setup_link | Where a setup link stands. The first check after the person finishes returns the API keys (and the server key, if requested); they are not shown again. While they're still on the page, check again every few seconds. |
create_setup_link | Gets TraceTail API keys for the person you work for: returns a link to give them, where they sign in with an emailed code and add a card or continue without a card, and a token. Then call check_setup_link with its id and token every few seconds: once they've finished, it returns an API key for each site (and a server key if you asked), once. |
get_integration_coderead-only | The exact install command and code to add TraceTail browser fingerprinting (a stable visitor ID for each browser, without cookies) to a web app built with the given framework, with where each file goes. Works without an API key (keyless mode, no sign-up); pass the site's public API key to fill it in. |
get_pricingread-only | TraceTail's prices and limits (1,000 identification requests free every month, then $0.10 per 1,000), with the monthly cost at a given volume and the same volume on Fingerprint (FingerprintJS) for comparison. |
read_docs_pageread-only | Returns a page of the TraceTail site as Markdown: "/docs" (the full documentation), "/pricing", "/vs-fingerprintjs", "/" (overview) or a blog post. |
search_docsread-only | Searches TraceTail's documentation, pricing, comparison and blog for a topic (e.g. "next.js", "rate limits", "ad blockers", "GDPR", "server-side verification") and returns the matching sections with their URLs. |
