Papertrade AI README

Code

https://papertrade-ai.ninabrekkerese.workers.dev/mcp

One URL, OAuth 2.1, no API keys. Your wallet signs once to register a session key that can trade but cannot withdraw, and the server enforces the limits you choose: margin per trade, leverage, daily size, open positions and markets. Every trade is previewed and needs your confirmation.

What you can ask

"What are BTC and ETH doing on Papertrade right now?"
"Show me the Papertrade liquidation map for ETH."
"Who are the top 10 Papertrade traders this week? What are they holding?"
"Analyze wallet 0x...: win rate, biggest trade, equity curve."
"If I long BTC with $20 at 500x, where is my liquidation price?"
"Preview a $15 ETH short at 800x, then open it if I confirm."
"Close all my BTC positions."

On clients with MCP Apps support (Claude, ChatGPT, VS Code, Goose) results render as an interactive trading card with a live chart.

Security

Non-custodial. Your wallet signs one EIP-712 RegisterSessionKey message, the same one the official Papertrade app signs for one-click trading. The session key is scoped by the exchange contract to open, close and cancel. It cannot withdraw or transfer.
Guardrails in code, not in the prompt. Margin per trade, leverage, rolling 24h position size, open positions and markets are checked on the server before any intent is signed.
Preview, then confirm. open_position needs a signed quote from preview_trade for the identical trade, valid for 3 minutes.
Encrypted per app. Each app's session key is encrypted with a key derived from that app's own access token.
Revoke in one click at /account.

Develop and self-host

bash

git clone https://github.com/nirholas/papertrade-ai && cd papertrade-ai
npm install
npm test           # unit tests
npm run dev        # local Worker on http://127.0.0.1:8787

Deploy your own copy to Cloudflare Workers with one KV namespace and one secret: Self-hosting. The package also exports the tool registry, policy engine and intent signing for use in your own agent: import { TOOLS, runTool } from 'papertrade-ai'.

Path	What
`src/tools/registry.ts`	Every tool: schema, annotations, implementation
`src/core/`	Papertrade API client, EIP-712 intents, bust price math
`src/worker/`	Cloudflare Worker: OAuth provider, MCP, REST, pages
`src/cli.ts`	stdio server and `login` CLI
`src/web/`	MCP Apps widget, connect and account pages
`docs/`	Documentation (rendered to the website)
`scripts/build-site.mjs`	Website, `llms.txt`, sitemap, discovery files, manifests

Risk

Papertrade positions use real USDC. At 1000x leverage a 0.1% move against you liquidates the position and the full margin is lost. Papertrade AI is independent open-source software, not affiliated with Papertrade, and not financial advice.
