Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-gway list all connected MCP servers"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A standalone CLI gateway that aggregates multiple MCP (Model Context Protocol) servers behind a single HTTP/SSE endpoint with Code Mode — reducing LLM input token usage by up to 92% when using multiple MCP servers.
Multi-Server Aggregation — Connect to multiple MCP servers (HTTP, SSE, Stdio, Streamable HTTP) and expose them through a single endpoint
Code Mode — 4 meta-tools that let LLMs discover and use tools dynamically without loading all schemas upfront
OAuth 2.0 Support — Built-in OAuth flow with dynamic client registration (RFC 7591) and token storage
Hermetic Sandbox — Starlark-based sandbox for safe code execution
MCP Protocol Compliant — Works with Claude Desktop, Cursor, and any MCP-compatible client

}Command | Description |
| Add an MCP server and generate |
| Remove an MCP server |
| Update tools for a server |
| List all connected servers |
| Show tool signatures for a server |
| Refresh connection and re-discover tools |
| Start the gateway server |
When connected, the gateway exposes 4 meta-tools:
Tool | Description |
| List all available |
| Read function signatures from a stub |
| Get detailed documentation for a tool |
| Execute code in a sandboxed Starlark interpreter |
For servers requiring OAuth (e.g., Supabase):
# Trigger OAuth flow
mcp-gway refresh supabase --auth
# Or store token manually
mkdir -p ~/.config/mcp-gway/tokens
echo '{"access_token": "YOUR_TOKEN"}' > ~/.config/mcp-gway/tokens/supabase.json# Install dependencies
