Ripplet: local code graph MCP helps coding agents assess change impact with fewer tokens
sh4rkwav3 · reddit · 2026-10-22
- Developer sh4rkwav3 released Ripplet, a local code graph MCP for AI coding agents, targeting the pain of agents repeatedly searching and reading files to understand how a change affects the codebase.
- Key capabilities:
- Builds a graph of code relationships (symbols, callers, dependencies, affected tests) so agents navigate connections instead of rediscovering them;
- Change impact analysis: flags what might break when a function, symbol, or interface changes, and detects stale callers or broken relationships after edits;
- Author observed lower token usage in testing, though savings depend on task and codebase.
- Runs fully locally with a graph plus SQLite — no cloud service, LLM API, or vector DB. Multi-language, works with any MCP-compatible coding agent; available on GitHub and PyPI, feedback requested.
