Tradeonyx MCP Server

TradeOnyx MCP Server

Connect TradeOnyx to Claude, ChatGPT, Gemini or any other MCP-capable assistant. Log trades by voice, have the assistant read your journal back to you, and let it ground its answers in your actual trading history instead of guessing.

TradeOnyx is a trading journal with pattern detection: it imports trades from 40 brokers and runs 28 detectors over your own history to surface what repeats in your trading. This repository documents its MCP server. It contains no product code.

Endpoint

https://tradeonyx.io/mcp

Transport is HTTP with JSON-RPC 2.0. Authentication is a Bearer token in the Authorization header. The server implements initialize, tools/list and tools/call, and speaks protocol version 2025-06-18.

An unauthenticated call answers honestly rather than hanging:

curl -s -X POST https://tradeonyx.io/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

# {"jsonrpc":"2.0","id":null,"error":{"code":-32001,"message":"Unauthorized"}}

Getting a token

1. Create an account at tradeonyx.io. The free tier is permanent and asks for no payment details.
2. Open Settings → Integrations and create an MCP token.
3. Copy it immediately. The raw token is shown once; only a SHA-256 hash is stored, so a lost token cannot be recovered, only replaced.
4. Revoke any token from the same screen at any time.

Tokens carry 256 bits of entropy. Treat one like a password: it grants the same access to your journal that you have.

Connecting an assistant

Any client that speaks MCP over HTTP works. For a client configured through a JSON file, the shape is:

{
  "mcpServers": {
    "tradeonyx": {
      "url": "https://tradeonyx.io/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN_HERE"
      }
    }
  }
}

Assistants that support remote MCP connectors directly (Claude's Connectors, for example) can add the endpoint through their own UI, including an OAuth flow, so no token needs to be pasted by hand.

What you can do with it

A few things people actually use it for:

• Log a trade in a sentence. "I bought 0.5 lots EURUSD at 1.0840, stop at 1.0810, because the London range broke upward." The assistant fills the fields and writes the reasoning into the journal next to the trade.
• Write the evening review by talking. The assistant reads back the day's trades, asks what you were thinking, and files the answers as a journal entry.
• Ask what actually happened. "Which of my setups lost money this month, and what did those trades have in common?" — grounded in your own rows, not in a guess.
• Prepare the session. Pull the daily briefing and the planned playbooks before the open.

Tools

44 tools. 41 are available on the free tier; three bulk aggregations require Pro Plus. Daily call caps apply per plan and are shown in the app.

Privacy and security

• Servers are in Germany, data stays in the EU, GDPR applies. Processors are named in the privacy policy.
• Tokens are stored as SHA-256 hashes; the raw value exists only in your clipboard.
• Every tool resolves data through the authenticated user. A token reaches exactly the account it belongs to.
• Deleting your TradeOnyx account erases the associated data, including the access log for your requests.

Found a security issue? Please report it privately to the address in our security.txt (hello@tradeonyx.io) rather than opening a public issue.
