  <Tab title="Cursor">
    <PreviewButton href="https://cursor.com/install-mcp?name=Channel3&config=eyJ1cmwiOiJodHRwczovL21jcC50cnljaGFubmVsMy5jb20vIn0%3D">Install in Cursor</PreviewButton>

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

    ```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
    {
      "mcpServers": {
        "Channel3": {
          "url": "https://mcp.trychannel3.com/"
        }
      }
    }
    ```

  <Tab title="VS Code">
    <PreviewButton href="https://vscode.dev/redirect/mcp/install?name=Channel3&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.trychannel3.com%2F%22%7D">Install in VS Code</PreviewButton>

    Or add to `.vscode/mcp.json`:

    ```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
    {
      "servers": {
        "Channel3": {
          "type": "http",

  <Tab title="Claude Code">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    claude mcp add --transport http --scope user Channel3 https://mcp.trychannel3.com/
    ```
  </Tab>

  <Tab title="Claude">
    In Claude on web, desktop, or mobile, go to **Settings → Connectors → Add custom connector** and paste:

    ```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
    https://mcp.trychannel3.com/
    ```

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