Nothing serious here today

Today is the operative word: we check Backtester every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 9

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

build

build_series

Build named time series from a run form. Needs version, data, and series.

build_signal

Build named trading signals from a run form. Needs version, data, series, and signals.

data

list_data

List available price data, fields, dates, limits, and whether reports can be retained for publishing.

prices

get_prices

Read historical prices for a run form. Needs only version and data.

report

report

Run a backtest and show its results. Supply strategyExplanation in plain terms for the widget. In your reply, explain the rule, always show Return vs. SPY (summary.returnVsSpyPct in percentage points, or Unavailable), and give one takeaway or limit supported by the report. Choose any additional cards using stats. Use scoreSeries for a separate score panel. Use chartSeries to select named report series and set their legend labels, line or bar types, colors, and line patterns. Keep the interpretation about this historical test. To publish this exact result later, pass its reportId to save_strategy after the user asks to save it to the website.

save

save_strategy

PUBLIC: anyone can see the saved page. Publish a completed report to the public website after the user asks to save it. Use the reportId returned by report, a public slug, and client-authored page and presentation choices. Never submit or invent result numbers. Adds it to the strategy directory without rerunning the strategy. Existing slugs require expectedKey to replace a different result. setAsHome changes the home page only when explicitly requested.

share_report

PUBLIC: the report is listed in the public strategy library, and anyone can see it. Make a report public so it can be shared, and return its page URL. Needs only the reportId returned by report. The page text comes from the report itself. Sharing the same report again returns the same URL. The report widget calls this when the visitor presses its share icon.

simulate

simulate

Simulate historical fills and account balances. Needs the full run form.

strategies

list_strategies

List published website strategies, their URLs, and their current keys. Use a current key as expectedKey only when the user asks to replace that saved strategy.

Backtester — questions

Answers built from our own checks of this server.

What can Backtester do?

It exposes 9 tools, read directly from the server on our last check. Among them: build_series, build_signal, get_prices, list_data, list_strategies, report and 3 more. 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 Backtester working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 342 ms. The bar chart above shows every period we have measured.

How do I connect Backtester?

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 Backtester need an API key?

No. Backtester completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Backtester?

It answers our handshake in 342 ms on average, which is faster than 41% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
