Verdict

Pick IDE Index MCP Server if you want a hosted/remote server with nothing to install, and you need the broadest set of tools.

Pick Serena if you prefer the more popular, battle-tested option, and you want a local (stdio) server that keeps data on your machine.

Add IDE Index MCP Server

Install / run

claude mcp add --transport http --scope user intellij-index http://127.0.0.1:29170/index-mcp/streamable-http

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "ide-index-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://127.0.0.1:29170/index-mcp/streamable-http"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.

Add Serena

Install / run

uvx --from git+https://github.com/oraios/serena serena start-mcp-server

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "serena": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/oraios/serena",
        "serena",
        "start-mcp-server"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.
