Script / Read

Reads the content of a script file and returns it as a string. Use 'script-update-or-create' tool to update or create script files.

Inputs

• filePath — required .cs path. Throws if missing on disk.
• lineFrom (default 1, 1-based) — start line; clamped into valid range.
• lineTo (default -1 = end-of-file, 1-based) — inclusive end line; clamped into valid range.

Behavior

Reads the file with File.ReadAllLines and slices [lineFrom..lineTo] (inclusive). The slice indices are clamped — passing out-of-range lineFrom/lineTo is forgiving (read returns at-most the whole file).

How to Call

unity-mcp-cli run-tool script-read --input '{
  "filePath": "string_value",
  "lineFrom": 0,
  "lineTo": 0
}'

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

unity-mcp-cli run-tool script-read --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool script-read --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.
