Strategy Arena Lab · MCP

Plug your AI into the Lab.The judge decides.

Claude, GPT, Gemini, Grok, DeepSeek or a model running on your PC can drive the Strategy Arena Lab: write a rule, backtest it, search thousands of variants on your graphics card, export the Pine for TradingView. Then the judge replays it on data nobody has seen and answers: winner or mirage?

Why plug your AI into the Lab

Your AI, your GPU

1,000,000 strategy variants in about 20 seconds on an RTX 4080 Super (Lab 235 measurement, 7 October 2026, legacy execution semantics). Every row that is kept is replayed on the CPU reference engine.

Even a small model

Small models running on your own PC complete the whole path in 6 calls: start_here, then datasets, validation, backtest, sweep and Pine export.

A judge, not a cheerleader

An AI is very good at finding a rule that worked in the past. The sealed proof keeps a test period aside, compares with Buy & Hold on the same windows and counts every variant tried, so luck is not mistaken for skill.

Plug your AI into the Lab in 3 steps

The Lab speaks MCP, the protocol that lets an AI use software. Your AI client starts a small local script; the script talks to the Lab running on your PC.

Start the Lab first. It opens a local connection on 127.0.0.1 with a new token for each session.
In the Lab: More tools → AI control → Copy the MCP config. The Lab fills in the real path of the script on your PC.
Paste it in your AI client (examples below), restart the client, then ask: “call start_here”.

Requirement: Node.js 20.3 or newer for the connection script. Replace PATH_COPIED_FROM_THE_LAB with the path the Lab gives you.

Claude Desktop

File: %APPDATA%\Claude\claude_desktop_config.json (Windows).

{
  "mcpServers": {
    "strategyarena-lab": {
      "command": "node",
      "args": ["PATH_COPIED_FROM_THE_LAB"]
    }
  }
}

Cursor

File: ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project).

{
  "mcpServers": {
    "strategyarena-lab": {
      "command": "node",
      "args": ["PATH_COPIED_FROM_THE_LAB"]
    }
  }
}

LM Studio

In LM Studio: Program → Install → Edit mcp.json. Pick a model that supports tool calls.

{
  "mcpServers": {
    "strategyarena-lab": {
      "command": "node",
      "args": ["PATH_COPIED_FROM_THE_LAB"]
    }
  }
}

opencode

File: opencode.json in your project (or ~/.config/opencode/opencode.json).

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "strategyarena-lab": {
      "type": "local",
      "command": ["node", "PATH_COPIED_FROM_THE_LAB"],
      "enabled": true
    }
  }
}

What your AI sees: the essential profile

By default the Lab shows a short list of tools with compact answers, so that small models can drive it too. start_here gives the whole path with ready-to-send arguments.

start_here
list_sandbox_datasets
validate_sandbox_strategy
run_sandbox_backtest
run_sandbox_sweep
start_sandbox_job
sandbox_job_status
export_sandbox_pine
analyze_pine_strategy
compare_tradingview_trades
prove_sandbox_script
begin_local_quick_proof
list_sandbox_experiments
suggest_lab_capability

Need every tool? Add "--profile", "full" after the script path in args (or set STRATEGY_ARENA_MCP_PROFILE=full), then restart the client.

The TradingView judge

TradingView's Strategy Tester is the author's tool: it shows what the author chose to test, with no sealed period. The Lab acts as the second opinion. It exports the exact Pine, you paste TradingView's List of Trades back, and compare_tradingview_trades checks every trade.

6 of the 6 leaderboard strategies, 234 of 234 trades, give the same trades one by one in the real TradingView, quantities included (Lab 236 export, test of 8 October 2026).

Open TradingView (partner link). Strategy Arena may earn a commission on an eligible purchase; a free account is enough to compare trades. It never changes a verdict.

Security: everything stays on your PC

The Lab listens only on 127.0.0.1, with a new 64-character token for each session. Nothing is exposed to your network.
Your strategies, data and results stay on your machine. The MCP connection sends nothing to Strategy Arena.
No tool places an order, opens TradingView, publishes anything or starts a payment.
Backtests and sweeps describe the past. Only the sealed proof gives a verdict, and it can say INCONCLUSIVE.
The Windows installer is not signed yet: download it only from strategyarena.io and compare the SHA-256 published on the download page.

Free and Operator

	Free	Operator 29 EUR/month
MCP connection, essential profile, backtest, sweeps, Pine export	✓	✓
Sealed proof “Winner or mirage?”	✓	✓
TradingView comparisons	limited	unlimited
Background GPU jobs above 200,000 variants, Think above 100,000	—	✓
Night mode and multi-asset jobs	—	✓

Paying never changes a verdict.

When a request needs Operator, the Lab tells your AI once, in one sentence. The AI never buys anything.

Launch access and founder offer

Launch access is not open yet. When it opens, every account created or signed in during the launch window gets full Operator access in the Lab for free, without a card, until a fixed end date announced here.

Founder member offer: accounts created during the launch (opening planned for 15 October 2026) can then keep Operator at 19 €/month instead of 29 €/month, for as long as the subscription stays active.

Two MCP servers, two jobs

The Lab is local and computes on your machine. The site also offers an online MCP server (https://strategyarena.io/mcp, Streamable HTTP) to read the public catalogue and proofs: MCP for agents.

Educational research and backtesting tool. Past results, not a forecast. No investment advice.
