Grep.app Code Search

MCP service at https://mcp.grep.app (http) with 1 tool.

Requirements

mh CLI must be installed. If not available, install with:
bash curl -fsSL https://raw.githubusercontent.com/vaayne/mcphub/main/scripts/install.sh | sh

Usage

List tools: mh -u https://mcp.grep.app -t http list
Get tool details: mh -u https://mcp.grep.app -t http inspect searchGitHub
Invoke tool: mh -u https://mcp.grep.app -t http invoke searchGitHub '{"query": "pattern"}'

Notes

Run inspect before invoking unfamiliar tools to get full parameter schema
Timeout: 30s default, use --timeout <seconds> to adjust
Important: This searches for literal code patterns (like grep), NOT keywords
Use actual code that would appear in files, not descriptions

Tools

Tool	Description
`searchGitHub`	Find real-world code examples from public GitHub repositories. Searches for literal code patterns across millions of repos.

Search Tips

Good queries (literal code patterns):

useState(
import React from
async function
(?s)try {.*await

Bad queries (keywords - won't work well):

react state management
how to use hooks

Examples

# Find useState usage patterns
mh -u https://mcp.grep.app -t http invoke searchGitHub '{"query": "useState("}'

# Find async/await patterns
mh -u https://mcp.grep.app -t http invoke searchGitHub '{"query": "async function fetch"}'

# Find import patterns
mh -u https://mcp.grep.app -t http invoke searchGitHub '{"query": "from \"openai\""}'
