Agent skill

type-get-json-schema

Generates a JSON Schema for a given C# type name using reflection. Supports primitives, enums, arrays, generic collections, dictionaries, and complex objects. The type must be present in any loaded assembly. Use the full type name (e.g. 'UnityEngine.Vector3') for best results.

Type / Get Json Schema

How to Call

bash
unity-mcp-cli run-tool type-get-json-schema --input '{
  "typeName": "string_value",
  "descriptionMode": "string_value",
  "propertyDescriptionMode": "string_value",
  "includeNestedTypes": false,
  "writeIndented": false
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

bash
unity-mcp-cli run-tool type-get-json-schema --input-file args.json

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool type-get-json-schema --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name Type Required Description
typeName string Yes Full C# type name to generate the schema for. Examples: 'System.String', 'UnityEngine.Vector3', 'System.Collections.Generic.List<System.Int32>'. Simple names like 'Vector3' are also accepted when unambiguous.
descriptionMode string No Controls the type-level 'description' field. Include: keep on the target type only. IncludeRecursively: keep on the target type and inside $defs entries. Ignore: strip all type-level descriptions. Default: Ignore.
propertyDescriptionMode string No Controls 'description' fields on properties, fields, and array items. Include: keep on the target type's own properties/items only. IncludeRecursively: keep on all properties/items including those inside $defs entries. Ignore: strip all property/item descriptions. Default: Ignore.
includeNestedTypes boolean No When true, complex nested types are extracted into '$defs' and referenced via '$ref' instead of being inlined. Useful for large or recursive types. Default: false.
writeIndented boolean No Whether to format the output JSON with indentation for readability. Default: false.
