Can I send an SMS using the agent?

Yes! Use the `send_sms` tool with the recipient's phone number and your message content. Your agent will trigger the dispatch through CallFire instantly.

How do I check the status of a specific call?

Simply ask the agent to `get_call_details` and provide the Call ID. It will retrieve the latest status, such as 'finished' or 'failed', directly from CallFire.

Does the integration allow creating a new voice broadcast?

The current toolset is focused on individual actions and querying (Read-Only/Individual Dispatch) for operational control. Massive broadcasts should be configured via the CallFire web dashboard.

CallFire + Claude Desktop FAQ

Common questions about integrating CallFire 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.
