bigjai/tokennuke

This is a code indexing server that gives Claude surgical access to large codebases without burning context tokens. It uses tree-sitter to parse 10 languages into ASTs, then stores symbols in SQLite with FTS5 and vector embeddings for hybrid search. You get 15 tools including get_symbol for O(1) byte-offset retrieval (grab a 200-byte function from a 40KB file), search_symbols with semantic and keyword matching, call graph traversal with get_callers and get_callees, and index_repo to pull down any GitHub or GitLab repository without needing git installed. Incremental indexing via SHA-256 hashing means re-indexing after one file change takes milliseconds. Reach for this when you're building agents that need to navigate unfamiliar codebases or doing refactoring work where you need to trace dependencies before moving code around.

Readme

TokenNuke

Intelligent code indexing MCP server. 15 tools, 10 languages, tree-sitter AST extraction, hybrid search (FTS5 + vector), call graphs, remote repo indexing, incremental indexing.

Save 99% of tokens — get exact function source via byte-offset seek instead of reading entire files.

Formerly codemunch-pro. Same code, better name.
