> 3 MCP server(s) over Streamable HTTP, each wrapping a different part of the Daisycon API and authorized separately: connect to the ones you need, one at a time.

**Connection**

---

Every server speaks JSON-RPC 2.0 over a single POST endpoint. A server requiring OAuth registers its client dynamically, so no client ID has to be configured in advance: approve the authorization prompt the first time it connects. An anonymous server needs no credential at all.

Primary protocol version `2026-07-28` needs no `initialize` handshake: each request carries its own version, identity and capabilities in `params._meta`. The legacy revisions `2025-11-25`, `2025-06-18`, `2025-03-26`, `2024-11-05` are also accepted, and a client speaking one negotiates it through `initialize`.

**Claude Code and Claude Desktop**

```json
{
    "mcpServers": {
        "daisycon-advertiser": {
            "type": "http",
            "url": "https://mcp.daisycon.com/advertiser/mcp"
        },
        "daisycon-publisher": {
            "type": "http",
            "url": "https://mcp.daisycon.com/publisher/mcp"
        },
        "daisycon-campaigns": {
            "type": "http",
            "url": "https://mcp.daisycon.com/campaigns/mcp"
        }
    }
}
```

Or, one server at a time:

```bash
claude mcp add --transport http daisycon-advertiser https://mcp.daisycon.com/advertiser/mcp
claude mcp add --transport http daisycon-publisher https://mcp.daisycon.com/publisher/mcp
claude mcp add --transport http daisycon-campaigns https://mcp.daisycon.com/campaigns/mcp
