Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

script-read scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

Input

Name Type Required Description
filePath string Yes The path to the file. Sample: "Assets/Scripts/MyScript.cs".
lineFrom integer No The line number to start reading from (1-based).
lineTo integer No The line number to stop reading at (1-based, -1 for all lines).

Input JSON Schema

  "type": "object",
  "properties": {
    "filePath": {
      "type": "string"
    },
    "lineFrom": {
      "type": "integer"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
