ASTra MCP

ASTra MCP is an open-source server that builds a knowledge graph of your codebase using AST parsing, semantic embeddings, and PageRank algorithms. It integrates with Claude Code, Cursor, Codex, and Windsurf to provide AI assistants with surgical context—only the 5–25 most relevant functions per task instead of entire files. The system runs fully local with zero cloud dependency.

Developers use ASTra to slash token consumption by 98.9%, reduce API costs, and avoid context window limits. The maker built it with Claude Code. Installation takes three commands, and the knowledge graph persists across sessions, enabling the assistant to understand cross-file structure without re-reading code repeatedly.
