Requirements

Python 3.12 is required — tree-sitter-languages does not yet have wheels for Python 3.13+.

​
Install VecGrep

uv tool install --python 3.12 vecgrep

​
Register with Claude Code

Run once — works for every project: 
claude mcp add --scope user vecgrep -- vecgrep
This registers VecGrep in your user config (~/.claude.json) so it’s available globally across all projects. Starts instantly — no download delay on Claude Code launch.
