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 MCP Tools for Pydantic AI (8)

These 8 tools become available when you connect Perplexity AI Alternative to Pydantic AI via MCP:

chat

Requires the model ID (e.g. "sonar", "sonar-pro", "sonar-reasoning") and messages array in JSON format. Each message must have a "role" ("user", "assistant" or "system") and "content" (text). Optionally set max_tokens, temperature (0-1), top_p (0-1), search domain filter, and whether to return images or related questions. Returns the assistant's response with citations. Send a chat message to a Perplexity model

chat_pro

Requires messages array in JSON format. Optionally set max_tokens and temperature. Returns the assistant's response with citations. Send a chat message to the Sonar Pro model for enhanced responses

chat_with_reasoning

Perplexity AI Alternative + Pydantic AI FAQ

Common questions about integrating Perplexity AI Alternative MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer — your Perplexity AI Alternative MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
