What we checked ourselves
Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 8 Sept 2026We checked that the link to the project still resolves.
- 13 Sept 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 1 Sept 2026We read the project's own documentation and found no sign that development has stopped.
Where this sits among the 47 tools we list in MCP connectors
- No API key required28 of 47
- Keeps your data on your own machine17 of 47
- Commercial use confirmed as allowed45 of 47
- Requires terminal commands3 that do not →
Only 16 of the 47 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
What it does
Returns the exact snippets an agent needs instead of making it read files, which the project measures at roughly 99% fewer tokens than grep-plus-read, with full-codebase indexing and search completing in under a second. Notably it runs entirely on CPU — no API keys, no GPU, no external service — and exposes an MCP server so agents can query it directly. The speed and reduction figures are the project's own benchmarks, so verify on your repository. MIT.
