Is any real money involved?

No. Poshkan is a paper-trading simulator — every account, balance, and trade is 100% virtual. AI assistants can practice strategies, but nothing real can be won or lost.

How does authentication work?

Claude Desktop uses a secure Poshkan OAuth sign-in and consent screen. Clients that accept bearer headers can instead use a personal API token (pk_…) from settings → AI/MCP access. Every connection is scoped to the signed-in user's paper accounts and can be revoked.

Which MCP clients are supported?

Claude Desktop and other OAuth-capable remote MCP clients can connect directly. Codex, Claude Code, the OpenAI API, and other Streamable HTTP clients can also connect with a Poshkan bearer token.

Can an AI make up fill prices?

No. Every trade is priced server-side from live market data at execution time, and order fills are claimed atomically. The assistant decides what to trade; Poshkan decides the price.

Nothing. The account, the MCP server, and the market data are free — no card required.

🤖 Give your AI assistant a paper-trading account

The Poshkan MCP server connects compatible AI assistants to a real-time paper-trading platform: live quotes, technical indicators, and broker-style order execution on US stocks, crypto, and leveraged forex — all with 100% virtual money.

Ask your assistant to analyze a chart and it can pull the candles itself. Ask it to act on the analysis and it can place the trade — a market order, a limit order at a better price, or a leveraged forex position with a stop-loss and take-profit attached. Because every dollar is virtual, it's a consequence-free sandbox for AI-assisted trading: strategy experiments, portfolio reviews, or a morning "check my positions" routine.

Things you can ask Claude

"Record my SPY / XLF / XLE hypothesis, strategy version, entry and exit rules, 3 trading-day hold and sizing before trading. Record no-trade decisions and append later reviews separately."
"Check BTC-USD on the 1-hour chart. If RSI is oversold near support, buy $2,000 worth on my crypto account."
"Review my stock account: what's my total P&L, and which holding looks weakest technically?"
"Open a EUR/USD short, 1 mini lot, stop-loss above the last swing high, take-profit at 2R."
"Place limit buys 3% below the current price on my whole watchlist, expiring end of day."
"List my open forex positions and close anything with more than $50 floating profit."

Setup — about two minutes

Create a free Poshkan account (no card) and add a paper-trading account or two — stocks, crypto, or forex.
Connect your client below.

Claude Desktop

Open Settings → Connectors → Add custom connector, name it Poshkan, and enter this URL:

https://www.poshkan.com/api/mcp/mcp

Claude opens Poshkan in your browser. Sign in and choose Allow access. No API key or desktop extension is needed.

Codex / ChatGPT desktop

In Poshkan, open the settings menu → AI/MCP access and create a token. Add a Streamable HTTP MCP server using this endpoint and the token as a bearer token:

https://www.poshkan.com/api/mcp/mcp
Authorization: Bearer pk_YOUR_TOKEN

Claude Code

claude mcp add poshkan --transport http "https://www.poshkan.com/api/mcp/mcp" \
  --header "Authorization: Bearer pk_YOUR_TOKEN"

OpenAI API and other MCP clients

It's a remote server over streamable HTTP — endpoint https://www.poshkan.com/api/mcp/mcp, authenticated with Authorization: Bearer pk_…. The OpenAI Responses and Agents APIs can pass the same token in their MCP authorization field.

OAuth-capable clients can connect directly without creating a personal token.

Built to be safe to hand to an AI

Virtual money only. No deposits, no withdrawals, no broker connection — the worst case is a bruised virtual ego.
Server-side prices.Fills always use live market data fetched by the server at execution time; a confused model can't invent a fill price.
User-scoped access. OAuth connections and personal tokens are tied to your account, every call is checked against your paper accounts, and access can be revoked.
Real trading rules. Asset-class limits, margin requirements, stop-outs, and order validation are enforced by the same code that runs the app.
