Built on the Robinhood and Coinbase MCPs
Autonomous trading with hard limits
The brokers shipped the primitives. Warden turns them into a product: describe your strategy in plain English and the agent trades your accounts through those MCPs, inside rules it can't see or break.
- Works with your existing accounts. Warden runs no exchange and no trading API of its own.
- Runs 24/7 on managed infrastructure. Nothing to set up or keep alive.
- Reads realtime market data and reasons through every order, in the open.
- Hard limits enforced in code, with a kill switch on your phone.
One strategy, end to end
Your words become a machine that answers to you.
01 / DESCRIBE
Written like you'd say it.
No code, no config, no terminal. You write what you want in plain English and approve exactly what the agent will be allowed to do before it runs.
02 / COMPILE
Strategy in. Instructions and limits out.
Warden compiles your words into agent instructions plus hard limits that live in code, outside the model. The agent can't see them or talk its way past them.

03 / REASON
It thinks before it trades.
The agent reads realtime market data and reasons through every decision, then writes the rationale down. Deliberate on purpose: judgment you can audit, not a black box and not a reflex.

04 / EXECUTE
Orders clear the guardrails or they don't happen.
Every order passes the policy engine before it reaches your broker. Blocked orders never leave the building, and you get a receipt for every intervention. One tap halts everything.

Managed runtime
You run nothing.
The DIY version of agentic trading means MCP configs, a desktop AI tool and a session you have to keep alive, then months of hoping it's still doing the right thing. Warden hosts your agent on its own infrastructure, connects it to the same Robinhood and Coinbase MCPs, streams it realtime market data and watches it around the clock. It keeps working when you close the app, next week and the week after. You get the receipts, not the ops job.
The Risk Console
Rules the agent can't argue with.
Every proposed order is checked against your policies before it reaches your broker. A separate monitor watches drawdown and exposure around the clock and can halt the agent even mid task.
Daily loss limit
$200 per day
A breach halts the agent on the spot.
Per order cap
$500 notional
Checked before any order leaves Warden.
Position cap
10% per ticker
No single position outgrows your book.
Ticker allowlist
VOO AAPL NVDA +9
The agent trades these and nothing else.
Trading window
09:30 to 16:00 ET
Nothing fires while you sleep, unless you want it to.
Circuit breaker
3 losses, 24h pause
Cooling off is automatic after a losing streak.
Kill switch
One tap
Halt the agent, cancel open orders, flatten to cash. Works even when the agent is mid task.
Example policies. You set your own. Tightening a limit is instant. Loosening one takes a 24 hour cooling period, on purpose.
Honest limits
What Warden won't promise.
No software can cap your losses through an overnight gap, a trading halt or a fast market. An exit at your limit still needs an open market and a buyer on the other side. Products that imply otherwise are lying to you.
So Warden doesn't promise a floor. It shows your estimated worst case exposure before a strategy goes live, labels every limit with what it can and can't catch, and hands you a receipt every time a guardrail fires: what was stopped, why and the state of your account at that moment.
Warden also never picks stocks or produces trade ideas. You author the strategy. Warden executes it faithfully and enforces your rules. It's the brake and the dashboard, not the driver.
