@hxlee418 shipped RowTrail (github.com/adam2go/rowtrail), an Apache-2.0 early-alpha local data tool: read-only SQL over CSV/TSV/Parquet, exact results saved on disk, bounded observations via CLI or MCP, and zero internal model calls with no API key. v0.1.0-alpha.2 publishes native packages for macOS arm64 and Linux x86_64.

Key Takeaways

  • Agents explore local tables with read-only SQL and bounded observations instead of loading whole tables into context.
  • Native Rust binaries with zero internal model calls; no Python, Node, or Docker required.
  • Apache-2.0 early alpha with CLI, persistent NDJSON sessions, and stdio MCP.
