vexp is an MCP server that gives AI coding agents structural awareness of your codebase. Instead of letting the agent read entire files, it pre-computes a dependency graph with tree-sitter and serves only the relevant code nodes — full source for what matters, signatures for everything else. Benchmarked on FastAPI (800 files, 42 runs, Claude Sonnet 4.6): 58% cheaper, 22% faster, 63% fewer output tokens per task. Also does cross-session memory — observations are linked to code graph nodes. When the code changes, stale context is auto-flagged. Single Rust binary + SQLite. Zero cloud, zero telemetry. Works with any MCP agent (Claude Code, Cursor, Copilot, Windsurf, aider, etc). Free tier, no account needed. |
