Can the AI automatically update a subscriber's custom field values?

Yes! By using the `update_person` tool, your agent can modify any existing custom field values for a specific subscriber identified by their email or ID in seconds.

How do I trigger an automation sequence for a new user?

Simply ask the agent to run the `trigger_automation` action. You'll need to provide the slug of the automation and the target person's email address.

Does this integration allow for bulk deletion of my entire audience?

No. The current toolset focuses strictly on managing individual subscriber records and queries. Destructive actions on the entire audience structure are not exposed to ensure your data remains secure.

Audienceful + Claude Desktop FAQ

Common questions about integrating Audienceful MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
