reflection-method-call

Method C# / Call

Call C# method. Any method could be called, even private methods. It requires to receive proper method schema. Use 'reflection-method-find' to find available method before using it. Receives input parameters and returns result.

Match levels (apply to typeName, MethodName, Parameters)

• typeNameMatchLevel / methodNameMatchLevel (default 1 — contains ignoring case): 0 ignore filter, 1 contains-ic, 2 contains-cs, 3 starts-with-ic, 4 starts-with-cs, 5 equals-ic, 6 equals-cs.
• parametersMatchLevel (default 2 — equals): 0 ignore filter, 1 count matches, 2 equals.

Inputs

• targetObject (optional) — for instance methods. When null, a new instance is created from the declaring type. Required shape: { type, value } (value is deserialized to type).
• inputParameters (optional) — list of { type, name, value }. Names are enhanced against the resolved method signature if omitted.
• executeInMainThread (default true) — Unity API calls should keep this true; set false only for thread-safe pure logic.

How to Call

unity-mcp-cli run-tool reflection-method-call --input '{
  "filter": "string_value",
  "knownNamespace": false,
  "typeNameMatchLevel": 0,
  "methodNameMatchLevel": 0,
  "parametersMatchLevel": 0,
  "targetObject": "string_value",
  "inputParameters": "string_value",
  "executeInMainThread": false
}'

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

unity-mcp-cli run-tool reflection-method-call --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool reflection-method-call --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
filter	any	Yes	Method reference. Used to find method in codebase of the project.
knownNamespace	boolean	No	Set to true if 'Namespace' is known and full namespace name is specified in the 'filter.Namespace' property. Otherwise, set to false.
typeNameMatchLevel	integer	No	Minimal match level for 'typeName'. 0 - ignore 'filter.typeName', 1 - contains ignoring case (default value), 2 - contains case sensitive, 3 - starts with ignoring case, 4 - starts with case sensitive, 5 - equals ignoring case, 6 - equals case sensitive.
methodNameMatchLevel	integer	No	Minimal match level for 'MethodName'. 0 - ignore 'filter.MethodName', 1 - contains ignoring case (default value), 2 - contains case sensitive, 3 - starts with ignoring case, 4 - starts with case sensitive, 5 - equals ignoring case, 6 - equals case sensitive.
parametersMatchLevel	integer	No	Minimal match level for 'Parameters'. 0 - ignore 'filter.Parameters', 1 - parameters count is the same, 2 - equals (default value).
targetObject	any	No	Specify target object to call method on. Should be null if the method is static or if there is no specific target instance. New instance of the specified class will be created if the method is instance method and the targetObject is null. Required: type - full type name of the object to call method on, value - serialized object value (it will be deserialized to the specified type).
inputParameters	any	No	Method input parameters. Per each parameter specify: type - full type name of the object to call method on, name - parameter name, value - serialized object value (it will be deserialized to the specified type).
executeInMainThread	boolean	No	Set to true if the method should be executed in the main thread. Otherwise, set to false.
