/script-read

name: script-read
description: Read a `.cs` script file and return its content as a string. Supports a 1-based `lineFrom`/`lineTo` slice for partial reads. Pair with 'script-update-or-create' to write back.

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: > ```bash > unity-mcp-cli run-tool script-read --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > 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.
