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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.01342 |
| Opus 5 | $0.00016 | $0.00671 |
| Sonnet 5 | $0.00007 | $0.00268 |
| Haiku 4.5 | $0.00003 | $0.00134 |
Grade A, and why
setup-mcp-server 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 7d 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.
This is a copy
100% identical to setup-mcp-server — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Setup mcp-rubber-duck
You are setting up mcp-rubber-duck as an MCP server in an AI coding tool.

1. Determine target tool
If $ARGUMENTS specifies a tool name, use it. Otherwise ask the user:
Supported tools: claude-desktop, claude-code, cursor, windsurf, vscode, continue
2. Detect platform
Run uname -s to detect macOS / Linux / Windows (Git Bash). This affects config file paths.
3. Detect install method
Check in order:
which mcp-rubber-duck— if found, usemcp-rubber-duckas the command- If we're inside the mcp-rubber-duck repo (check for
package.jsonwith"name": "mcp-rubber-duck"), offer from-source vianode dist/index.js - Default to
npx -y mcp-rubber-duck
4. Ask about providers
Ask the user which providers to include. Offer these choices:
- OpenAI (
OPENAI_API_KEY) — most popular - Google Gemini (
GEMINI_API_KEY) - Groq (
GROQ_API_KEY) — fast inference - Ollama (local, no key needed)
- CLI agents (Claude CLI, Codex, Gemini CLI, Aider)
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

setup-mcp-server is a skill published in the GitHub repository HoziMurayama/Multi-LLM-Debugging-Bridge (5 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 1,342 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to setup-mcp-server, differing in 0 lines, and is treated as a copy.
