Rattlewatch does not always answer

Over the last week it answered 92.5% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

changes

list_changes

List recall and requirement changes since an ISO-8601 timestamp (e.g. '2026-09-01T00:00:00+00:00'). Includes newly published recalls and rule changes, each with its source URL.

recalls

search_recalls

Search official US recall records by product name, brand, model, or UPC. Covers CPSC consumer products and FDA food, drug and device enforcement. Returns only cited records from the store, each with a source URL and a match score. If nothing matches, returns an empty list rather than guessing.

requirement

get_requirement

Get cited market-entry requirements for a product subject in a given market (e.g. subject='childrens_products', market='US'). This is a small curated set, not a full regulatory database: CPC, CPSC eFiling, EU GPSR, CE marking, REACH SVHC, RoHS and California Prop 65. Returns each fact with its official citation URL and last-verified date.

verify

verify

Check a claim or product query against the store. Returns only cited records (recalls and requirements) that match. Explicitly reports 'no verified record' when nothing matches -- it never synthesizes an answer, so absence means 'not in the store', not a negative claim.

Rattlewatch — questions

Answers built from our own checks of this server.

What can Rattlewatch do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_requirement, list_changes, search_recalls, verify. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Rattlewatch working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 44 of 91 checks got a reply (48.4%), average response time 489 ms. The bar chart above shows every period we have measured.

The registry lists Rattlewatch as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Rattlewatch?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Rattlewatch need an API key?

No. Rattlewatch completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Rattlewatch?

It answers our handshake in 489 ms on average, which is faster than 24% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Rattlewatch open source?

The code is open source: it is published under the MIT licence, written in Python and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at rattlewatch.rattled.ca, which runs on its operator's own terms.
