Chart Library - Market-state research MCP Server

Market memory for AI, with published research for agents and people. Version 6.3.3 marks failed public tool calls as MCP errors while preserving their structured recovery details. Invalid requests explain how to correct the inputs; stale publication versions retain instructions to restart from the current overview.

People who work with finance, market data and pattern recognition and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
