Code search across millions of public GitHub repositories via grep.app. Use before writing or planning code to find real-world usage of libraries, frameworks, APIs, algorithms, or syntax patterns. Prefer this over web search for code examples.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# grep.app
Search real-world code examples from over a million public GitHub repositories. Powered by [grep.app](https://grep.app) MCP. No API key required.
## searchGitHub
Find real-world code examples by searching for **literal code patterns** (like grep), not keywords.
- `query` (required): literal code pattern (e.g. `useState(`, `import React from`, `async function`)
- `language`: array of language filters (e.g. `Python`, `TypeScript`, `TSX`, `Java`, `Go`, `Rust`, `C#`, `YAML`, `Markdown`)
- `repo`: filter by repository (e.g. `facebook/react`, `vercel/`) — partial names match
- `path`: filter by file path (e.g. `src/components/Button.tsx`, `/route.ts`) — partial paths match
- `useRegexp`: interpret query as regex (default: `false`). Prefix with `(?s)` for multiline
- `matchCase`: case-sensitive search (default: `false`)
- `matchWholeWords`: match whole words only (default: `false`)
### Basic usage
```bash
uv run --script scripts/mcpcall.py searchGitHub query:"useState("
uv run --script scripts/mcpcall.py searchGitHub query:"getServerSession" --args '{"language": ["TypeScript", "TSX"]}'

How to install
mdr add archibate/agent-skills/grep-app@sha256:270e5dda623b4d50The line at the top of this page pins the label git:20260721.bc6b489, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
