Frequently asked questions
How do I find my Steam Web API Key?
Log in to your account and navigate to steamcommunity.com/dev/apikey to generate or copy your unique key.
Can I see my friends' status via AI?
Yes! The list_steam_friends tool allows your agent to retrieve high-fidelity status metadata and recently played games for your friend list.
How do I check my total playtime for a game?
Use the list_owned_games tool to retrieve your complete high-fidelity library along with total playtimes (in minutes) for each app.
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 Steam MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
