fish-bridge - Session Knowledge Graph MCP Server

Session-scoped knowledge graph engine for AI chat context compression. Converts raw AI chat (40k+ tokens) into a compact typed knowledge graph (~300–800 tokens) and writes it to .github/copilot-instructions.md or CLAUDE.md - automatically included in every AI turn across all modes (ask, edit, agent). No MCP server required for the core workflow. It runs locally over stdio via the published package.

People connecting productivity tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
