Frequently asked questions
Can I review the full history of calls and text messages for a specific contact?
Yes. Use list_calls to browse all call records and get_call with a specific Call ID for full details including duration, recording URL, and disposition. For SMS, use list_texts to browse messages and get_text for individual message content and delivery status.
Does CallFire require two separate credentials?
Yes. CallFire uses HTTP Basic Authentication with an API Login (username) and an API Password. Both are generated in your CallFire account under Settings > API Access. They are separate from your dashboard login credentials.
Can I monitor my active broadcast campaigns and their delivery status?
Yes. The list_campaigns tool retrieves all voice and text broadcast campaigns with their status (active, paused, finished). Use get_campaign with a Campaign ID to inspect configuration details, delivery rates, and audience targeting. Combine with list_webhooks to verify event-driven notifications are configured correctly.
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.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
