Jev-powered semantic code search for coding agents — find behavior across repositories via CLI or MCP, with exact source excerpts and line numbers.
Find code by what it does. JevGrep helps coding agents find relevant code when they do not know the file name or symbol to search for.
Ask a question such as “Where is session expiry handled?” and JevGrep scans the authorized repository, asks Jev to score all eligible fragments, then returns the original source excerpts with their paths and line numbers. The calling agent can read those files in detail and continue its work with less exploratory context.
Use the CLI or connect a coding agent through the local MCP server.
JevGrep is useful when a coding agent needs to:
- locate behaviour without knowing the exact identifier; - understand a feature spread across implementation, configuration and tests; - reduce the amount of repository exploration placed in the agent's main context; - retrieve exact source excerpts instead of a generated summary.
It complements exact tools such as rg. If you already know the symbol or literal, ordinary text search is usually faster.
- Node.js 24 - npm - a TypeSafe AI, Vercel AI Gateway or OpenRouter API key
JevGrep searches every valid UTF-8 text file, regardless of repository language or extension.
The unscoped package name jevgrep belongs to a different project. Use the complete scoped name above when installing. The installed command is still jevgrep.
To install a development checkout instead:
npm link makes the jevgrep command available from any directory on the computer.
