Grep.app

Use Grep.app directly over HTTP; no mcporter needed.

Required shell helper

Source the bash helper from this skill once per shell:

source "${SKILLS_DIR:-skills}/grep-app/scripts/grep-app.sh"

If SKILLS_DIR is unavailable, source the same file from your local skills/ checkout.

Then use grep-app <subcommand> everywhere below.

When to use

• Real usage patterns for APIs, config, and framework code
• Public GitHub code only
• Literal search first; regex when needed

Quick start

grep-app search "useState(" f.lang=TypeScript
grep-app search "errgroup.WithContext(" f.repo=golang/sync
grep-app regex "useState\\(" f.lang=TypeScript

Useful filters

Pass Grep.app filters as query params:

• f.repo=owner/repo
• f.path=src/
• f.lang=TypeScript
• case=true
• words=true

Environment

• Tracked template: .env.example
• Optional override: GREP_APP_BASE_URL

Notes

• Public GitHub repos only.
• search is literal by default.
• regex sets regexp=true automatically.
• Grep.app returns HTML snippets inside JSON; use jq to extract metadata like repo/path first.
• Check licenses before reusing copied code.

Validation

./scripts/test-grep-app-http.sh
