Setup

Free tier URL (no key):

https://mcp.trychannel3.com/

Have a key? Send it as an X-API-Key header. See free tier for the difference.

Or add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "Channel3": {
      "url": "https://mcp.trychannel3.com/"
    }
  }
}

Or add to .vscode/mcp.json:

{
  "servers": {
    "Channel3": {
      "type": "http",
      "url": "https://mcp.trychannel3.com/"
    }
  }
}

claude mcp add --transport http --scope user Channel3 https://mcp.trychannel3.com/

In Claude on web, desktop, or mobile, go to Settings → Connectors → Add custom connector and paste:

https://mcp.trychannel3.com/

Claude connects from its own servers, so one connector covers every Claude surface.

Turn on developer mode under Settings → Security and login, then create an app under Settings → Plugins with this URL and authentication set to none:

https://mcp.trychannel3.com/

codex mcp add Channel3 --url https://mcp.trychannel3.com/

{
  "mcp": {
    "Channel3": {
      "type": "remote",
      "url": "https://mcp.trychannel3.com/",
      "enabled": true
    }
  }
}

That’s it. To confirm the tools are available, ask for something like “find in-stock merino wool sweaters under $150 with buy links.” See usage examples for more.
