Connect your assistant

You add NYO once and sign in. There is no key to create and nothing to paste - your assistant asks for permission, you approve, and it can start asking other models for help.

Claude - web, desktop and mobile

One click. Works on every Claude plan; the free plan allows one added connector.

Add to Claude

If the button is blocked, add it by hand in Claude under Connectors → Add custom connector, with this address:

https://your-router.example/mcp

Claude opens with the name and address filled in. Press Add.
Press Connect, then sign in here with Google or your email.
Approve the request. You are back in Claude, ready to go.

On a Team or Enterprise plan, an owner adds it once under Organization settings → Connectors, and everyone else just presses Connect.

Claude Code

One command, then /mcp inside Claude Code to sign in.

claude mcp add --transport http router-llm https://your-router.example/mcp

ChatGPT

Connect NYO as a custom MCP server from ChatGPT on the web. Access depends on your plan and workspace permissions.

Add NYO. In ChatGPT on the web, open Plugins, choose +, then select Add custom MCP server.
Configure and authorize. Enter NYO's public MCP address and choose OAuth. If ChatGPT prompts during setup or tool scanning, sign in and approve NYO before continuing. Use this address: https://your-router.example/mcp.
Create and use. Review the discovered tools and choose Create as a plugin. In a new chat, select NYO from the tools menu before asking it to get another model's opinion.

https://your-router.example/mcp

Custom MCP connections are available on the web. Business, Enterprise and Edu support full MCP; some plans limit custom MCP servers to read-only tools, so NYO’s ask tool, which spends credits to call another model, needs full MCP access. Workspace admins can restrict who may add or use custom servers. See OpenAI’s current setup and availability details.

Cursor and everything else

Anything that can add a remote MCP server takes the same address and the same sign-in.

https://your-router.example/mcp

Then just ask

“Ask Kimi for a second opinion on this plan.”
“Which models can you reach through NYO?”
“Have GLM review this function and tell me what it would change.”

What connecting means

Your assistant acts as you, and only after you approve it. You can disconnect it at any time from the assistant's own settings.
What it sends is passed to the model provider that answers, and may be recorded so we can run and improve the service.
Every request is counted against your own account and balance, which you can see under Account.
