Frequently asked questions
Can I search for posts matching a specific tag across Tumblr?
Yes! Use the list_tagged_posts tool and provide your tag. Your agent will retrieve the latest posts from across the platform that use that specific tag.
How do I see the posts from a specific blog like 'officialtumblr'?
Run the list_blog_posts query with the blog name. You can optionally filter by type (e.g., 'photo' or 'quote') to see only the content you're interested in.
Is it possible to retrieve the avatar URL of a blog via AI?
Absolutely. Use the get_blog_avatar tool and provide the blog name. You can also specify an optional size to get the image URL that best fits your needs.
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 Tumblr MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
