Code Review Graph — Token-Efficient Codebase Context via MCP Reduce AI token usage by 6.8x average (up to 49x on monorepos) by giving the AI a structural map of your codebase instead of letting it read everything. Overview is an MCP server that uses Tree-sitter to parse your codebase into an AST graph stored in SQLite . When your AI assistant needs context for a task, it queries the graph first — getting only the files in the blast radius of your change — instead of reading every file in the directory.
