Stop wasting RAM & tokens
on duplicate MCP servers
Share MCP server processes across all terminals. One gateway, O(1) memory growth.
What is MCP?
Model Context Protocol (MCP) is an open standard that lets AI assistants use external tools—just like Docker lets apps use external services.
- Claude, Cursor, IDX can query your GitHub repos, databases, or browse the web
- MCP Servers provide these tools via stdio, HTTP, or Docker containers
- Each terminal traditionally spawns its own server processes—that's the problem
Think of MCP Gateway as nginx for AI tools—one gateway routing to shared backend processes.
Traditional MCP: Massive Duplication
Each terminal spawns its own MCP server processes. With 7 terminals using 2 servers each, you're running 14 duplicate processes.
Worse: traditional MCP sends full list_tools definitions (27,000+ tokens) with every single message—even if you never use most tools.

MCP Gateway: Process Sharing
All terminals connect to one lightweight gateway process. The gateway routes requests to shared backend servers—one Supabase process, one GitHub process—no matter how many terminals you open.

MCP Gateway
O(1) Memory
Add unlimited terminals without spawning new server processes. Memory stays constant.
Lazy Discovery
Tools load on-demand, not upfront. 98% token reduction vs traditional list_tools bloat.
No Docker Required
Stdio servers work natively. Docker optional for containerized isolation.
Hot Configuration
Add/remove servers without restarting your AI session. Agents can self-configure.
Server Types
Choose the right transport mode for each MCP server
HTTP Mode
Native HTTP servers. Fastest startup, lowest overhead.
Stdio + Wrapper
Auto-generated HTTP wrapper for stdio servers.
Docker
Containerized isolation for complex dependencies.
O(1) Memory Scaling
Add unlimited terminals without increasing memory usage
How It Works
Simple architecture: one gateway process routes to shared backends
Configure AI client
Point Claude Code or Cursor to http://localhost:8989/mcp
Stateless routing
Every request includes project or cwd context. Gateway loads that project's .env and routes to the right server.
Shared processes
Backend servers spawned once and shared. GitHub server handles all terminals. Supabase server switches credentials per request.
Intelligent scoping
Servers scoped globally (filesystem), per-workspace (memory graph), or per-credential (GitHub tokens). Gateway handles isolation automatically.
