Koskamo

Nexus-MCP

A local MCP server that provides AI coding agents with persistent project memory, live codebase architecture mapping, and hybrid code search capabilities. It runs offline without API keys, supporting multiple languages via tree-sitter and integrating with agents like Claude Code and Cursor to reduce token usage and improve context retention across sessions.
