Grep.app MCP

Use Grep.app to search real code in public GitHub repos. Not keyword search; use literal code patterns.

When to use

• •Real usage patterns, syntax, or config examples
• •Regex search across many repos
• •OSS only (no private repos)

Quick start

searchGitHub query="useState(" language='["TypeScript","TSX"]'
searchGitHub query="(?s)useEffect\\(\\(\\) => {.*removeEventListener" useRegexp=true language='["TSX"]'

Notes

• •Filter with repo, path, language for precision
• •Use useRegexp=true for regex; prefix (?s) to match across lines
• •Public GitHub only; check licenses before reuse

Query templates

See assets/query-templates.json.
