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: 
    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\""}'
