# Setup

Free tier URL (no key):

```

Have a key? Send it as an `X-API-Key` header. See [free tier](/mcp/free-tier.md) for the difference.

**Cursor**

[Install in Cursor](https://cursor.com/install-mcp?name=Channel3\&config=eyJ1cmwiOiJodHRwczovL21jcC50cnljaGFubmVsMy5jb20vIn0%3D)

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

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

**VS Code**

[Install in VS Code](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)

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

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

**Claude Code**

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

**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.

**ChatGPT**

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

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

**Codex**

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

**OpenCode**

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "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](/mcp/usage.md) for more.
