Type-safe FantasyData (SportsDataIO) tools

Every response from `get_nfl_scores` is validated against your Pydantic models. If the schema shifts, the agent stops immediately rather than processing junk data. Your agent logic stays clean. You define the structure, and the MCP server ensures the data from `get_mlb_scores` matches your requirements every time.

Reliable player data for Pydantic AI

Call `get_nba_player_details` with full confidence. Your agent receives structured, validated stats that fit perfectly into your existing Pydantic workflows. Use `list_mlb_players` to verify rosters. The framework catches missing fields or type mismatches before they cause runtime errors in your analytical models.

Model-agnostic sports intelligence

Switch between local and cloud models while keeping your FantasyData (SportsDataIO) integration constant. The Pydantic AI toolset handles the heavy lifting. You gain a unified interface for all league data. Calling `get_nfl_schedule` returns data that your agent can trust, regardless of which model is currently running.
