Every number comes from a tool, not a guess
Should I bring a jacket to Austin this weekend?
get_forecast()get_outdoor_recommendation(Sat)get_outdoor_recommendation(Sun)
No jacket needed. Austin is forecast to reach 97°F Saturday and 102°F Sunday, both far above the 60°F threshold. Take sunscreen instead, the UV index peaks at 8.4.

The problem
AI chat answers about the real world often sound right and invent the numbers. For anything you act on, every figure needs a source.
What I built
An MCP server with 5 weather tools (current conditions, forecast, advice, severe alerts, compare cities) and a Databricks agent that picks the right tool, calls it and answers from what came back.
Tech & why
Thin tools, adapters that hold every web call, and the judgement (thresholds like 60°F for a jacket) in plain code, published in the tool's own description.
- Python
- MCP
- Databricks
- Agent Bricks
The result
Answers like "No jacket needed: 97°F Saturday and 102°F Sunday", where every number came from a tool call, plus a public live endpoint.
How this agent is built
Every AI agent has the same five parts. Here is what each one is in SkyCast-AI, so you can judge any agent the same way.
- ModelA Databricks Agent Bricks agent.
- HarnessThe agent chooses one of 5 MCP tools, calls it and answers only from the result.
- GuardrailsThresholds live in code and in each tool's description; the public server needs a bearer token; no raw web calls inside a tool.
- KnowledgeLive forecasts from Open-Meteo and severe-weather alerts from the National Weather Service.
- ToolsCurrent weather, forecast, outdoor advice, severe alerts, compare cities.
