How do I get a Perplexity API key?

Log in to the [**Perplexity AI Settings**](https://www.perplexity.ai/settings/api), go to **API Key Management** and click **Create API Key**. Copy the key immediately — it starts with `pplx-` and won't be shown again.

What models are available?

Use the `list_models` tool to see all available Perplexity models. Key models include sonar (web-grounded chat), sonar-pro (enhanced reasoning), sonar-reasoning and sonar-reasoning-pro. Each model provides real-time web search with citations.

Can I filter search results to specific domains?

Yes! Use the `chat` or `search` tools with the search_domains parameter to limit results to specific websites (e.g. ["wikipedia.org","github.com"]). This is useful for research focused on trusted sources.

Do responses include citations?

Yes! All Sonar models return responses with inline citations and a list of source URLs. The citations are embedded in the response text as numbered references [1], [2], etc., and the full source URLs are provided in the response metadata.

Perplexity AI Alternative + Claude Desktop FAQ

Common questions about integrating Perplexity AI Alternative 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.
