Most trading bots sell you an edge. This one tests whether there is one — and refuses to fake it.

Supported brokers

One toolkit, more brokers over time

Groww is live today. The broker layer is being abstracted so the same Claude tools work across platforms — your strategies and research don't change when the broker does.

What it does

Capabilities

Every order flows through one guarded path, so the safety switch can't be bypassed. Everything below is built on that foundation.

How it works

Claude drives it — through one guarded path

You work entirely from Claude. Every request flows through the MCP tools to your broker, and every order passes one guarded write — so the safety switch governs everything, no matter what you ask for.

Safety model

Real money is opt-in, never accidental

The default state places no real orders. You have to deliberately, repeatedly choose otherwise — and a beginner lock can make real orders impossible even then.

The honest verdict

A research bar strict enough to disappoint you

Run a hundred backtests and a few will look brilliant by chance. The harness is built to see through that. A strategy only earns a verdict it can defend out of sample.

Tested across rule-based strategies, a RandomForest, and a Transformer, this universe showed no robust edge. Model complexity didn't manufacture one — and the platform's value is telling you so instead of selling you a curve fit.

By design

What it won't do

The constraints are the product. Each of these is a deliberate refusal, not a missing feature.

• Place a real order by default. DRY_RUN is on until you turn it off, and a learning-mode lock can make real orders impossible entirely.
• Auto-trade tips or signals. Forwarded tips are captured and graded against their own forward returns — never obeyed. They're a known pump-and-dump vector.
• Fake a backtest. Net of charges and slippage, next-bar fills, no look-ahead — and it states its own survivorship and corporate-action caveats out loud.
• Claim an edge it can't defend. If a strategy can't clear the deflated-Sharpe bar out of sample, the verdict is no-edge — including the ML and Transformer candidates.
• Hold your money or your keys. You self-host with your own credentials; nothing is pooled and nothing is custodial.
• Pretend it's tax advice. The India tax classification is a preparation aid — real filing needs contract notes, full FIFO, and a CA.

How to use it

Run it with Claude in four steps

No clone, no Python — just Docker and a config block. The server runs on your machine; your credentials never leave it.
