Connect Claude, Cursor, and ChatGPT

Any MCP client connects to the same gateway URL. Choose the auth method the client supports: one-time OAuth sign-in, a scoped bearer token, or a config-file snippet.

{
  "mcpServers": {
    "ucl": {
      "url": "https://your-company.ucl.dev/mcp",
      "headers": { "Authorization": "Bearer ucl_<your-token>" }
    }
  }

Headless agents (LangChain, OpenAI, TypeScript)

For agents serving many end users, create one client per user and bind the org + end-user headers at connect time. The same agent key serves every tenant; per-user connectors act as the X-User-Id you pass.

from langchain_mcp_adapters.client import MultiServerMCPClient

client = MultiServerMCPClient({
    "ucl": {
        "transport": "streamable_http",
        "url": "https://your-company.ucl.dev/mcp",
        "headers": {
            "Authorization": "Bearer ucl_<agent-key>",
            "X-User-Id": "user@example.com",
        },
    }
})
