Frequently asked questions
How do I find my Campaign Monitor API Key?
Log in to your account, click on your profile (top right), navigate to Account Settings > API Key, and copy your unique token.
Can I manage multiple clients via AI?
Yes! The list_clients tool retrieves all sub-accounts, and you can use their IDs to manage lists and campaigns specifically for each client.
Does it support real-time campaign analytics?
The get_campaign_analytics tool retrieves the most current engagement metrics (opens, clicks, unsubscribes) directly from the platform.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
