Unity-MCP 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

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:

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

Or pipe via stdin (recommended):

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

Troubleshooting

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.
