Install

claude mcp add svelte-mcp -- npx -y @sveltejs/mcp

Run in your terminal. This exact command is what our harness runs in Claude Code; see the results above.

{
  "mcpServers": {
    "svelte-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@sveltejs/mcp"
      ]
    }
  }
}

Save as .cursor/mcp.json. This exact config is what our harness runs in Cursor; see the results above.

{
  "mcpServers": {
    "svelte-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@sveltejs/mcp"
      ]
    }
  }
}

Add to claude_desktop_config.json and restart Claude Desktop. Tested on the Linux beta; see the results above.

[mcp_servers.svelte-mcp]
command = "npx"
args = ["-y", "@sveltejs/mcp"]

Add to ~/.codex/config.toml (shared by the ChatGPT (Codex) CLI and the ChatGPT desktop app; Codex runs inside the ChatGPT desktop app). Tested with the ChatGPT (Codex) CLI bundled in the ChatGPT desktop app; see the results above.
