Common questions

Is FindSaunaPlunge — US cold plunge & sauna studios safe?

It passed 1 of 1 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 –, and the latest version (1.0.1) reached the registry 2 months 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 in developer mode.

What can I use instead?

FindSaunaPlunge MCP server

Model Context Protocol server for findsaunaplunge.com: cold plunge, sauna and contrast-therapy venues across US metros. get_data_freshness reports the current venue count and the dates the records were last checked. Every published temperature and price is read from the venue's own pages and carries its source URL, capture date and verbatim quote. Absent fields mean the venue does not publish that detail — never zero.

Endpoint: https://findsaunaplunge.com/mcp — Streamable HTTP, stateless, no auth, open CORS. GET serves human documentation; POST is JSON-RPC.
Registry: com.findsaunaplunge/findsaunaplunge (domain-verified).
Data: same records as the CC BY 4.0 feed /api/v1/venues.json; archived monthly at github.com/findsaunaplunge/data, DOI 10.5281/zenodo.22132913.

Tools

Tool	Arguments	Returns
`search_venues`	`query?`, `citySlug?`, `modality?`, `access?`, `maxDropInUsd?`, `limit?`	Compact venue records; filters AND-combine. `maxDropInUsd` matches only venues with a published drop-in price.
`get_venue`	`id`	The full feed record, including per-fact `sources`.
`list_cities`	—	Covered cities with venue counts and available modalities.
`get_city_stats`	`citySlug`	Counts, published price and temperature ranges, contrast-capable venues.
`get_data_freshness`	—	When the feed was built and the newest/oldest `lastVerified`.

Connect

# Claude Code

claude mcp add --transport http findsaunaplunge https://findsaunaplunge.com/mcp

Any client, by hand

curl -s -X POST https://findsaunaplunge.com/mcp -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_venues","arguments":{"citySlug":"austin-tx","modality":"cold_plunge","limit":3}}}'

Run it yourself

The handler needs nothing but the public feed, so it runs anywhere with Node 24+:

npm start                    # JSON-RPC over stdio, one message per line (= node src/serve.ts --stdio)

npm run http # Streamable HTTP on :8080 — POST /mcp (= node src/serve.ts) docker build -t findsaunaplunge-mcp . && docker run -i findsaunaplunge-mcp # stdio npm test # smoke test: stdio + HTTP against the live feed

Both modes read https://findsaunaplunge.com/api/v1/venues.json (override with FINDSAUNAPLUNGE_ORIGIN), so a self-hosted copy serves exactly what the site serves.

How it runs

src/mcp.ts is the whole server: one handleMcp(request, env) function mounted at /mcp inside the site's Cloudflare Worker. It has no dependencies. Tool results come from the static /api/v1/venues.json asset produced by the site build (fetched through the Worker's ASSETS binding and memoized per isolate), so the server can never disagree with the site and a deploy refreshes it automatically. server.json is the registry manifest.

This repository is the published source of that server. The site itself is not open source.

Design rules

Stateless: no sessions, no server-initiated SSE. Every POST is self-contained.
Unknown arguments are rejected with a message naming the valid ones, rather than silently ignored.
Nothing here is, or will be, a paid placement.

Licence

MIT — see LICENSE. The venue data the server serves is separately licensed CC BY 4.0.
