MCP server for the Pyon AI trading platform - research, strategy building, backtesting and optimization tools for Claude Code, Claude Desktop and Codex
MCP (Model Context Protocol) server for the Pyon trading platform. It lets AI agents - Claude Code, Claude Desktop, Codex, or any MCP client - drive Pyon end to end: search markets, generate research, build and edit node-graph strategies with AI, run backtests, diagnose problems, and optimize parameters with 2-D sweeps.
Runs over stdio, talks to api.pyon.io, and needs only Node 18+.
1. Sign in at app.pyon.io. 2. Open Account API Access. 3. Create a personal access token. It looks like pyk....
Set it as the PYONAPIKEY environment variable wherever the server runs.
Variable Required Default Purpose --- --- --- --- PYONAPIKEY yes - Personal access token (pyk...) PYONAPIURL no https://api.pyon.io API base URL override
Add to claudedesktopconfig.json (Settings Developer Edit Config):
Pyon turns a strategy description into a node graph literally. An indicator name the engine does not know, or a threshold outside an indicator's range, produces a strategy that backtests to zero trades and looks broken for no visible reason - an RSI 120 entry can never fire, because RSI is bounded 0-100.
So call getcapabilities before writing any strategy description, edit instruction, or sweep bound. It returns the real catalog: 61 market indicators with their value ranges and indicatorParams, 9 portfolio indicators, 8 operators, 8 trigger types, 13 action types, the 5 supported timeframes, the 3 quantityType modes, 7 option strategyType values, and the 47 tradable tickers.
