Parallel code search with Warp-Grep MCP. Use for codebase discovery, understanding how things work, data flow analysis, or when the user asks "how does X work" about the codebase.
Parallel codebase search. Runs 8 searches per turn for efficient discovery.
| 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 |
Warp-Grep is an MCP tool that activates automatically for natural language code questions. It:
| 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 |
| 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 |
