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

install-mcp 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 9d 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.

What it actually says

Install the Rhino-MCP-Platform plugin into Rhino using Yak (Rhino's package manager). $1 is the Rhino major version to target (e.g. 8). If omitted, default to 8.

  1. Locate the Yak CLI for Rhino $1. It ships with Rhino:
    • macOS: /Applications/Rhino $1.app/Contents/Resources/bin/yak
    • Windows: C:\Program Files\Rhino $1\System\Yak.exe
  2. Install the plugin from the public package server:
    yak install Rhino-MCP-Platform
    
  3. Restart Rhino $1 so the newly installed plugin is loaded.
  4. In Rhino, run the MCPStart command to confirm the plugin is available.

To upgrade an existing install, run yak update Rhino-MCP-Platform. To remove it, run yak uninstall Rhino-MCP-Platform.

What this file has done since we first saw it

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.
