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.
