Frequently asked questions
How do I find my Buffer Access Token?
Log in to your Buffer account, navigate to Settings > Personal Access Tokens, and generate a new token for your integration.
Can I post to multiple social profiles at once?
Yes! The schedule_social_post tool accepts a JSON array of profile IDs, allowing you to broadcast the same update across all your connected platforms.
How do I check my scheduled queue?
Use the list_pending_posts tool with a specific profile ID to retrieve all updates currently waiting to be published.
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 Buffer MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
