How to Set Up and Use MCP All In One
MCP All In One is a service aggregator that combines multiple MCP servers into a single unified MCP endpoint, letting AI clients connect to one server instead of configuring each MCP server individually. It supports both stdio and HTTP transport, provides real-time status monitoring of running sub-services, auto-reconnects on service failure, and exposes built-in MCP tools for dynamically adding, removing, and viewing sub-service configurations without editing files manually. DevOps engineers and power users who run many MCP servers will find it useful for centralizing management and reducing client configuration complexity.
Prerequisites
- Node.js 18+ and npm (for npx execution)
- Any MCP-compatible client: Claude Desktop, Claude Code, Cursor, Trae, or Cherry Studio
- The individual MCP servers you want to aggregate already installed or runnable via npx/uvx
Add MCP All In One to Claude Code
For Claude Code users, add the aggregator as a user-scoped MCP server with a single command. It runs the latest version automatically via npx.
claude mcp add mcp-all-in-one -s user -- npx -y mcp-all-in-one@latest stdioOr configure in Claude Desktop / other clients
For Claude Desktop, Cursor, or other MCP clients, add the configuration block to your MCP config file. The `stdio` argument sets the communication mode.
{
"mcpServers": {
"mcp-all-in-one": {
"command": "npx",
"args": ["mcp-all-in-one@latest", "stdio"]
}
}
}Add sub-services via AI prompts
Once connected, use natural language to configure additional MCP services inside mcp-all-in-one. No manual file editing required — the aggregator manages sub-service configuration through its own MCP tools.
Monitor and manage running services
Ask your AI assistant to show the current service configuration and status. Services can be added, updated, or removed dynamically through conversational commands.
Verify aggregated tools are visible
After adding sub-services, check that tools from those services appear in your AI client's available tools list. The aggregator proxies them under the single mcp-all-in-one namespace.

Sub-service tools are not visible in the AI client after adding them
After adding a sub-service via prompt, restart your MCP client or trigger a tool refresh. Some clients cache the tool list at startup and require a reconnect to discover newly proxied tools.
A sub-service fails to start or auto-reconnect does not work
Verify the sub-service command is executable independently (e.g., test `npx chrome-devtools-mcp@latest` in your terminal). If the command requires environment variables, they may need to be passed explicitly when configuring the service through the aggregator.
The aggregator itself fails to start with npx
Ensure you have Node.js 18+ installed and internet access for npx to download the package. Try `npx mcp-all-in-one@latest stdio` in your terminal directly to see error output, which is suppressed when launched as an MCP subprocess.
