Description
PigeonGraph stops coding agents from wasting 20+ turns on grep loops. It builds an in-memory knowledge graph locally with Node 24 SQLite WAL, connecting AST symbols and dynamic runtime routes for Claude, Cursor, and Gemini in a single turn. 100% local, MIT licensed

Could you build this?
Partial Building an MCP server is straightforward, but parsing multi-language ASTs, building incremental in-memory code knowledge graphs, and tracing dynamic routes accurately require non-trivial compiler and static analysis expertise.
What it would actually take: The architecture relies on Node.js/TypeScript using Tree-sitter or TypeScript Compiler APIs, SQLite in WAL mode for persistent graph caching, and Model Context Protocol (MCP) server endpoints. The hard part is building robust cross-language call graphs, resolving symbols across dynamic imports and framework-specific routing conventions, and maintaining sub-second query performance without memory bloat. This demands specialized knowledge of AST parsing, static analysis, and graph database optimization.
