👨‍💼 Nicely done! Now, when something goes wrong, LLMs get a clear, structured error message which they can use to generate a proper message for the end user. This makes the app much more robust and user-friendly, and helps everyone know exactly what went wrong and why.

With proper error handling in place, your tools are ready for real-world use—no more silent failures or confusing responses!

🧝‍♀️ We're going to make things a little bit more realistic than a Calculator MCP. I'm going to update everything to be a full journaling application that is 100% accessible through MCP, complete with database and everything. You can take a look at the diff here if you're curious to check out my changes. I will also be restructuring our MCP server to be structured in a similar manner as Cloudflare MCP servers are structured. We'll be moving over to a class. That change will be in the diff as well.
