MCP & Tool Protocols
JSON Schema
A standard for describing and validating the structure of JSON data.
Example
JSON Schema validates the fields an assistant supplies when calling a tool.
Why it matters
It gives software a shared way to check required fields and value types.
You'll hear it
“The structure check rejected the missing field.”
Can you control it?

The people building or running the AI choose this setup. An everyday user generally needs their help to change how this part works.
Common questions
- Does JSON Schema check real-world truth?
- No. It can check structure and specified rules, not verify every factual claim.
- Can a value be optional?
- Yes. The rules can distinguish required fields from those that may be absent.
- Do all tools support every version equally?
- No. Supported features can differ, so compatibility needs checking.
