How to connect
How to connect EmidLabs Backtest to Claude
The server address to paste into Claude settings:
https://mcp.backtest.emidlabs.com/mcp
- Open Claude (claude.ai or the desktop app).
- Go to Settings → Connectors.
- Click Add custom connector.
- Paste the server address copied below into Remote MCP server URL and click Add.
- In a chat, click + → Connectors and switch the new connector on.
Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.
Authorization
After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.
How to connect EmidLabs Backtest to ChatGPT
The server address to paste into ChatGPT settings:
https://mcp.backtest.emidlabs.com/mcp
- Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
- Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
- Open Settings → Connectors and click Create.
- Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
- Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
- In a new chat open + → Apps/Connectors and enable the connector.
OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.
Authorization
On first use ChatGPT opens the service's sign-in window. Sign in and approve access.
How to connect EmidLabs Backtest to Cursor
The server address to paste into Cursor settings:
https://mcp.backtest.emidlabs.com/mcp
Fastest: click Open in Cursor below and confirm the prompt.
Manually:
- In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
- Paste the JSON copied below into
~/.cursor/mcp.json(per project:.cursor/mcp.jsonin the repo root). - Save the file. The server appears in the MCP list; authorize it there if asked.
Authorization
If the service needs sign-in, an authorize button appears next to the server in the MCP list.
Server tool list (9)
Raw names from tools/list. Only developers need these.
| submit_confirmation_source | Runs a strategy against historical data purely to produce a signal timeline used to confirm OTHER backtests — not a backtest itself. Walks the same candles and evaluates the same DSL as submit_backtest, but never simulates a position: no trade, no PnL, no WinRate/drawdown, none of that applies here, because this strategy is never meant to be traded on its own. Returns immediately with an id and status — call get_confirmation_source to check completion, then pass that id as a confirmationSources sourceId in submit_backtest (e.g. only count an XRP entry once a BTC-neutral confirmation source agrees). Costs the same capacity as a regular backtest of the same size — the compute is identical, it just skips trade simulation. |
| list_available_assets | Lists every asset pair with real historical data, each with its supported timeframes and the date range actually available. Optional to call — submit_backtest already returns a clear error (with the real available range) when an asset or date range doesn't have data, so this is for up-front exploration or for recovering from an "unknown asset" error, not a required step before every submit_backtest. |
| submit_backtest_batch | Submits ONE strategy against MANY asset pairs in a single call — the same backtest you'd get from calling submit_backtest once per asset, without needing dozens of round trips. Returns immediately with a batchId (pass it to get_backtest_batch_results to fetch every asset's outcome, paginated) plus the per-asset id/status assigned right away. Best-effort: one bad asset pair (unknown, or its date range outside coverage) shows up with an error in that item only — every other asset in the batch is unaffected. Optionally accepts confirmationSources, applied identically to every asset in the batch — see submit_backtest's own confirmationSources argument for the full semantics. |
| get_backtest_batch_results | Fetches every asset's outcome from a submit_backtest_batch call, paginated. By default (waitForCompletion: true) polls internally until every item in the batch is done — a cheap check, not one that pages through everything — so one call returns the finished page. Each item has the same aggregate metrics and recency fields (recentTradeCount/recentAvgPnlR/recentOutcomes) get_backtest_result returns for a single backtest, plus assetPair/status/error, so the single-result and batch-result shapes never drift apart. totalCount/completedCount/failedCount/pendingCount come back on every page, not just the last, so you can tell the batch is done from a single pageSize=1 call. |
| get_backtest_trades | Fetches the closed-trade list for a completed backtest, paginated and sortable — the trade-by-trade detail get_backtest_result deliberately omits. Only closed trades ever appear; a position still open when the backtest's date range ends isn't represented here or anywhere else. Example: sortBy="exitTime", sortDirection="desc", pageSize=5 for the most recently closed trades. |
| get_backtest_result | Fetches a submitted backtest by id. By default (waitForCompletion: true) polls internally until it finishes, so one call returns one final answer — no need to poll from the caller's side. Only aggregate metrics are returned here, no trade-by-trade detail — call get_backtest_trades for that (paginated, sortable). Fetching many results from the same submit_backtest_batch call? Use get_backtest_batch_results instead. |
| submit_backtest | Submits a strategy for backtesting against historical OHLCV data. Returns immediately with an id and status — call get_backtest_result to fetch the outcome once it finishes. Testing the same strategy against many assets? Use submit_backtest_batch instead — one call per asset here adds up fast. Optionally accepts confirmationSources to only count a candidate Entry/Exit as a real trade once corroborated by a submit_confirmation_source result (multi-timeframe or cross-asset confirmation) — see the confirmationSources argument and submit_confirmation_source's own description. |
| get_confirmation_source | Fetches a submitted confirmation source by id. By default (waitForCompletion: true) polls internally until it finishes, so one call returns one final answer. No trade-outcome fields here at all (no PnlR/WinRate/...) — a confirmation source never opens a position. Once Completed, its id can be used as a confirmationSources sourceId in submit_backtest; its raw signal timeline is available separately via get_confirmation_source_signals. |
| get_confirmation_source_signals | Fetches a completed confirmation source's raw signal timeline, paginated — the actual data a backtest's confirmationSources requirement is checked against. Can easily run into the thousands for a frequent condition over a long range (every candle-condition match is a row, not just closed trades), which is why this is paginated from the start. Debugging/inspection only — you do NOT need this tool to make confirmationSources work, and should not fetch these rows to reconstruct the gating yourself. To actually gate a backtest by this source, pass its id directly as sourceId in submit_backtest's own confirmationSources array; the backend applies the backward-only state check against this exact timeline automatically, including the higher-timeframe-to-lower-timeframe alignment. Reimplementing that alignment by hand from this raw data is unnecessary and easy to get wrong (e.g. failing to correctly persist a higher-timeframe state across every lower-timeframe candle until the next higher-timeframe close). Use this tool only to sanity-check a source's signal density or diagnose an unexpectedly low ConfirmedSignalsCount after the fact. |
