-You can think of MCP as a bridge between your LLMs and your data and tools. Model Context Protocol was developed by Anthropic (the makers of [Claude](https://claude.ai)), but MCP can work with any Large Language Model provider that supports tool calling.

+We'll build a server that exposes two tools: `get-alerts` and `get-forecast`. Then we'll connect the server to an MCP host (in this case, Claude Desktop):

   Because servers are locally run, MCP currently only supports desktop hosts. Remote hosts are in active development.

+**Error: Failed to retrieve grid point data**
+
+This usually means either:
+1. The coordinates are outside the US
+2. The NWS API is having issues
+3. You're being rate limited
+
+Fix:
+
+- Verify you're using US coordinates
+- Add a small delay between requests
+- Check the NWS API status page

+**Error: No active alerts for [STATE]**
+
+This isn't an error - it just means there are no current weather alerts for that state. Try a different state or check during severe weather.
