Multi-LLM-Debugging-Bridge: Skill for Claude Code

.claude/skills/setup-mcp-server/SKILL.md

setup-mcp-server is a skill for Claude Code from HoziMurayama/Multi-LLM-Debugging-Bridge. It costs 33 tokens per session (1,342 once invoked), scanned A, a copy of setup-mcp-server, MIT.

A setup guide for adding the mcp-rubber-duck server to AI coding tools such as Claude Desktop, Cursor, VS Code, and Windsurf. MCP is a standard way for an AI tool to connect to extra services.

In plain words
What is it for?
Use it when installing mcp-rubber-duck and adding it to a user or project configuration. It helps configure the server for supported coding tools on macOS and Windows.
Why use it?
It removes the need to work out each tool’s configuration file, setting name, and environment-variable format by hand. It also points to troubleshooting information for common setup problems.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool; mentions Claude Code.

This is HoziMurayama/Multi-LLM-Debugging-Bridge's own configuration. It tells Claude Code how to work on Multi-LLM-Debugging-Bridge itself, so it is not a mod to install elsewhere.

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

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.

Setup mcp-rubber-duck

You are setting up mcp-rubber-duck as an MCP server in an AI coding tool.

Supported tools and config paths

Tool Config File (macOS) Key Notes
Claude Desktop ~/Library/Application Support/Claude/claude_desktop_config.json mcpServers Windows: %APPDATA%\Claude\claude_desktop_config.json
Claude Code (user) ~/.claude.json mcpServers Prefer claude mcp add CLI
Claude Code (project) .mcp.json mcpServers Shared via VCS
Cursor (project) .cursor/mcp.json mcpServers
Cursor (global) ~/.cursor/mcp.json mcpServers
Windsurf ~/.codeium/windsurf/mcp_config.json mcpServers Supports ${env:VAR}
VS Code .vscode/mcp.json servers Different key name! Uses ${env:VAR}
Continue .continue/config.yaml mcpServers (array) YAML format

ChatGPT supports MCP via UI only (Developer Mode > Add MCP Server), not a config file.

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:

  1. which mcp-rubber-duck — if found, use mcp-rubber-duck as the command
  2. If we're inside the mcp-rubber-duck repo (check for package.json with "name": "mcp-rubber-duck"), offer from-source via node dist/index.js
  3. 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.

Changes

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.
