The current elicitation implementation uses a generic JsonObject type for the requested_schema field in CreateElicitationRequestParam. This approach lacks type safety and does not enforce the structure defined in the MCP 2025-06-18 specification.

Current implementation:

pubstructCreateElicitationRequestParam{pubmessage:String,pubrequested_schema:JsonObject,// Too generic, no type safety}

According to the MCP specification schema, requestedSchema should have a strict structure:

requestedSchema: {
type: "object";
properties: {[key: string]: PrimitiveSchemaDefinition;};
required?: string[];}

Where PrimitiveSchemaDefinition is a union of:

  • StringSchema (with minLength, maxLength, format: "email" | "uri" | "date" | "date-time")
  • NumberSchema (with minimum, maximum, type: "number" | "integer")
  • BooleanSchema (with default)
  • EnumSchema (with enum: string[], enumNames?: string[])

                          The current elicitation implementation uses a generic JsonObject type for the requested_schema field in CreateElicitationRequestParam. This approach lacks type safety and does not enforce the structure defined in the MCP 2025-06-18 specification.
                          Current implementation:
                          pubstructCreateElicitationRequestParam{pubmessage:String,pubrequested_schema:JsonObject,// Too generic, no type safety}
                          According to the MCP specification schema, requestedSchema should have a strict structure:
                          requestedSchema: {
type: "object";
properties: {[key: string]: PrimitiveSchemaDefinition;};
required?: string[];}
                          Where PrimitiveSchemaDefinition is a union of:
                          • StringSchema (with minLength, maxLength, format: "email" | "uri" | "date" | "date-time")
                          • NumberSchema (with minimum, maximum, type: "number" | "integer")
                          • BooleanSchema (with default)
                          • EnumSchema (with enum: string[], enumNames?: string[])
