Regimen does not always answer

Over the last week it answered 59.6% 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.

regimen

regimen_describe_factors

List the market-condition factors Regimen slices performance by, with units, the upstream operation each is read from, and how it is bucketed. Call this when you need to know which factor keys exist or how to explain a bucket to a user. Takes no arguments, reaches no network, never changes.

regimen_evaluate_track_record

Answer whether a trading strategy’s measured performance is distinguishable from luck. Returns the Probabilistic Sharpe Ratio (the probability the true Sharpe beats a benchmark, corrected for sample length, skew and fat tails), a bootstrap confidence interval, and the Minimum Track Record Length — how long the record would have to run before the claim could be made at all. Use this whenever someone quotes a Sharpe ratio, a win rate or a return and you need to know whether the number means anything. It will frequently say the evidence is too thin; that is the intended answer, not a failure.

regimen_regime_map

Break a strategy’s returns down by the market conditions that held on each date — volatility, funding, open interest, positioning, sentiment, trend state — and report performance per bucket. Each factor also gets a permutation test: the observed best-to-worst spread is compared against spreads produced by randomly reshuffling the regime labels, so a flattering subset cannot pass itself off as a regime effect. Use this after regimen_evaluate_track_record when you need to know WHERE an edge comes from, or whether it is a bet on conditions that could end.

regimen_self_attack

Run Regimen’s own analysis against controls whose answer is known in advance: the strategy’s returns with the edge mathematically removed, and a simulated population of strategies with no edge at all. Returns whether the engine correctly found nothing in them, and where the real strategy’s confidence sits among pure-luck strategies of the same length and volatility. Use this when a user is entitled to ask why they should believe the verdict, or before quoting a result as evidence.

Regimen — questions

Answers built from our own checks of this server.

What can Regimen do?

It exposes 4 tools, read directly from the server on our last check. Among them: regimen_describe_factors, regimen_evaluate_track_record, regimen_regime_map, regimen_self_attack. 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 Regimen working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 52 of 91 checks got a reply (57.1%), average response time 328 ms. The bar chart above shows every period we have measured.

The registry lists Regimen 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 Regimen?

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

Does Regimen need an API key?

No. Regimen 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 Regimen?

It answers our handshake in 328 ms on average, which is faster than 49% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Regimen open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
