ctx++

Semantic code search and indexing using tree-sitter AST analysis across 13+ languages with call graph traversal and hybrid vector-keyword ranking.

A codebase intelligence MCP server that parses source files across 13+ languages using tree-sitter parsers to extract symbols, call graphs, and documentation. Indexes everything in SQLite with both full-text and vector search through Ollama or AWS Bedrock embeddings. Features hybrid ranking that combines BM25 scoring with call-graph connectivity analysis, enabling queries that find not just matching code but all code involved in a feature by walking real call relationships. Provides tools for indexing, semantic search, file skeletons, dependency traversal, and blast radius analysis of code changes.
