Do I need the server prefix combined with my API key automatically?

Mailchimp API keys usually have a suffix (like `key-us6`). The system will parse everything internally. Just paste the full API key into our simplified authentication box naturally.

Can I bulk add 5,000 users directly in a single conversational prompt?

While structurally possible via API logic, context windows prohibit reading arrays of 5000 units. Adding is handled dynamically unit by unit securely or in exceptionally tiny batches to bypass hard egress caps effectively.

Does the system allow firing off actual live campaigns immediately to massive audiences?

No. The MCP server prioritizes safe state changes (subscribers). Launching massive destructive dispatches is omitted from the handler array to avoid rogue AI actions firing misconfigured commercial payload sets blindly.

How does Windsurf discover MCP tools?

Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.

Can Cascade chain multiple MCP tool calls?

Yes. Cascade is an agentic system — it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.

Does Windsurf support multiple MCP servers?

Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
