NumberSchema shows "minimum", "maximum" as integer rather than number

[pawbhard]

What's broken?

The JSON schema is wrong (incorrect type, constraint, or field)

Where in the spec or docs?

modelcontextprotocol/schema/2025-11-25/schema.json

Line 2115 in 91a643c

"maximum": {

What should happen?

NumberSchema 'maximum'/ 'minimum' should be number type in JSON schema

What actually happens?

NumberSchema 'maximum'/ 'minimum' is of type integer JSON schema

Anything else?

JSON Schema:

modelcontextprotocol/schema/2025-11-25/schema.json

Line 2115 in 91a643c

"maximum": {

TS Schema:

modelcontextprotocol/schema/2025-11-25/schema.ts

Line 2267 in 91a643c

minimum?: number;

It might be happening as we are using the script to generate JSON schema and converting all numbers to integer.

modelcontextprotocol/scripts/generate-schemas.ts

Line 64 in 91a643c

`npx typescript-json-schema --defaultNumberType integer --required --skipLibCheck "${schemaTs}" "*"`

On similar line, Why we have integer in JSON schema as there is no integer type in JSON ? (Shouldn't everything be number)
