cctx-mcp 0.5.4

Cut AI agent token usage by 87%.
Structure-aware code analysis via the Model Context Protocol — returns symbol trees, dependencies, and docs instead of raw file contents.

Overview

CCTX-MCP — Code ConTeXt via Model Context Protocol. An MCP server that gives AI agents a structured view of source code without reading entire files.

Built for Claude, Cursor, OpenCode, and any MCP-compatible AI coding tool.
