Warp-Grep (MCP Server)

Parallel codebase search. Runs 8 searches per turn for efficient discovery.

When This Applies

Signal	Action
"How does X work?"	Use Warp-Grep
Data flow across files	Use Warp-Grep
Cross-cutting concerns	Use Warp-Grep
Understanding architecture	Use Warp-Grep

How It Works

Warp-Grep is an MCP tool that activates automatically for natural language code questions. It:

1. Interprets your question
2. Runs up to 8 parallel searches
3. Returns relevant code snippets with context

When to Use Warp-Grep

Use Case	Use Warp-Grep?
"How does authentication work?"	YES
Data flow analysis	YES
Understanding module interactions	YES
Finding all usages of a pattern	YES

---

When NOT to Use Warp-Grep

Use Case	Use Instead
Known function name	rg (ripgrep) or Grep tool
Known exact file	Just open it with Read
Simple existence check	Glob or rg
Single specific search	Grep tool

---

Query Tips

Good queries:

• "How does the payment processing flow work?"
• "Where are user sessions managed?"
• "How is error handling done in the API layer?"
• "What happens when a request comes in?"

Less effective:

• "Find function X" → Use rg or Grep instead
• "Open file Y" → Use Read tool
