How to add the grep.app MCP server to Claude Code

Server URL: https://mcp.grep.app
Sign-in: No sign-in. Paste the URL and it connects.
Our hands-on result: Works 6 of 6 tasks passed, tested Oct 16, 2026 with MCP TypeScript SDK (reference client).

Claude Code setup

claude mcp add --transport http grep-app https://mcp.grep.app

1. Run the command, then run claude mcp get grep-app to confirm it connected.

We ran the hands-on test in a reference client, not in Claude Code. This config follows Claude Code's documented format for remote (Streamable HTTP) servers. If it fails for you, tell us and we will retest.
