Why Pydantic AI?
Pydantic AI validates every Actionstep tool response against typed schemas, catching data inconsistencies at build time. Connect 8 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Actionstep integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your Actionstep connection logic from agent behavior for testable, maintainable code

Frequently asked questions
Can I list all my active legal matters using my AI agent?
Yes! Use the list_matters tool to retrieve a comprehensive list of all legal matters registered in your Actionstep system.
How do I check details for a specific matter?
Simply provide the Matter ID to the get_matter_details tool. Your agent will fetch the full metadata, status, and assigned team.
Does it support OAuth 2.0 authentication?
Yes, it uses OAuth 2.0. You'll need to generate a Client ID and Client Secret in your developer portal to create an access token.
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 Actionstep MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
