Features

Built for fast, secure, automated trading

Polytrader2 keeps data, keys, and strategy execution local, while connecting AI agents through MCP.

Local cache and auto sync

Market, account, order, and position data are cached locally and kept up to date automatically, so common actions respond fast.

System-protected keys

Keys are encrypted by the operating system, using DPAPI on Windows and Keychain on macOS.

Local strategy VM

Strategies run locally inside an isolated VM with controlled access to app capabilities and trade actions.

MCP for AI agents

Connect Claude Code, Codex, and other AI agents to market context and strategy workflows through the built-in MCP Server.

MCP

Connect AI agents to your local trading workspace

Polytrader2 runs a local MCP Server protected by a token. Claude Code, Codex, and other AI agents can access market context, account summaries, and strategy workflows without moving your keys to the cloud.

Before connecting

Enable the MCP Server in Polytrader2 settings

Copy the local endpoint and MCP token

Add Polytrader2 to Claude Code or Codex, then verify the connection

Claude Code

Run this command in your terminal to add Polytrader2 to Claude Code as a user-scoped MCP Server.

polytrader2-mcp

claude mcp add --transport http --scope user polytrader2 http://localhost:8708/mcp \
  --header "Authorization: Bearer <YOUR_MCP_TOKEN>"

In Claude Code, run /mcp and confirm polytrader2 is connected.

Strategy

Run strategies locally, with clear safety boundaries

Polytrader2 turns trading ideas into local bots. Strategies can use synced market data, connect to selected accounts, and run inside a controlled local environment.

Safety boundaries

Keys stay protected

Strategies never receive raw private keys. Signing and custody stay inside the desktop app.

Isolated execution

Strategy code runs in a controlled local VM instead of getting open access to your system.

Explicit trading path

Orders and cancellations go through Polytrader2 trading services and can be reviewed.

Open-source transparency

The execution model and safety boundaries can be inspected in the source code.

Strategy workflow

Write with AI

Use Claude Code, Codex, or your own tools to draft and refine strategy logic.

Run locally

Strategies execute on your desktop, using local market and account data.

Control access

Each strategy runs with limited app capabilities and explicit trading actions.

Review every action

Runs, logs, errors, orders, and cancellations are recorded locally.
