Type-safe court extraction via Pydantic AI

The `search_legal_entities` tool integrates with your type-safe agents to guarantee that extracted Brazilian court names match strict schemas. If the tool encounters an unexpected data structure, the framework fails loudly, keeping your data clean. This setup avoids the silent corruption common in loose legal parsers. Your Pydantic AI agent receives verified tribunal names that fit your exact data models.

Model-agnostic legal parsing

The `search_legal_entities` tool works with any LLM you configure in your Pydantic AI setup. You can run local models or commercial APIs while keeping your underlying legal dictionary consistent and reliable. This flexibility means you can swap models without rewriting your legal entity extraction logic. Your MCP Server connection handles the heavy lifting of identifying Brazilian regulatory bodies.

Direct HTTP toolset integration

The `search_legal_entities` tool connects using the unified HTTP toolset approach in Pydantic AI. You point the framework to the Vinkius endpoint, and it registers the MCP Server as a native tool. This modern setup replaces deprecated HTTP server classes, ensuring your legal pipeline stays compatible with future framework updates.
