additionalProperties in JSON InputSchema

[esgn]

Hi,
More of a question than an issue.

• If I want to make sure that messages including non supported parameters for my tool returns errors through mcp-framework I can use zod strict()
• To be completely thorough it's also possible to define in JSON Schema additionalProperties: false to make sure non supported parameters are not being sent. See here for MCP related example https://modelcontextprotocol.io/seps/1613-establish-json-schema-2020-12-as-default-dialect-f#3-schema-validation-requirements

If I'm not mistaken mcp-framework does not offer a way to set additionalProperties: false yet.
Do you think it might be useful to also support this feature ?

Thanks for all the work
