Quick Start: Claude Code CLI¶

Add the MCP server to Claude Code using the claude mcp add command:

Stdio transport (local):

Stateful mode with local filesystem¶

claude mcp add mcp-v8 -- mcp-v8 --directory-path /tmp/mcp-v8-heaps

Stateless mode¶

claude mcp add mcp-v8 -- mcp-v8 --stateless

SSE transport (remote):

claude mcp add mcp-v8 -t sse https://mcp-js-production.up.railway.app/sse

Then test by running claude and asking: Run this JavaScript: console.log([1,2,3].map(x => x * 2))
