auroraview: Skill for Claude Code

.codebuddy/skills/mcp-tester/SKILL.md

mcp-tester is a skill for Claude Code, Codex from loonghao/auroraview. It costs 59 tokens per session (3,623 once invoked), scanned A, original, MIT.

Instructions for testing and debugging a local AuroraView MCP Server. AuroraView is the project being tested, and an MCP server is a program that exposes tools to an AI assistant.

In plain words
What is it for?
Use it when changing the auroraview-mcp package, configuring mcp.json, testing tool implementations, or checking connections to a local AuroraView instance.
Why use it?
It helps configure the local server, start the required application, run tests, and investigate connection problems during development.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is loonghao/auroraview's own configuration. It tells Claude Code and Codex how to work on auroraview itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything auroraview configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is vx uv run python scripts/debug_client.py --test discover.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

mcp-tester scanned grade A with 1 finding 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 11d 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.

AuroraView MCP Tester

This skill guides testing and debugging of the local AuroraView MCP Server development version.

When to Use

  • Testing local MCP server changes before committing
  • Debugging MCP tool implementations
  • Verifying MCP server functionality
  • Troubleshooting connection issues
  • Running integration tests with AI assistants

Prerequisites

Before testing, ensure:

  1. Local environment is set up:

    cd packages/auroraview-mcp
    vx uv sync
    
  2. AuroraView instance is running (for connection tests):

    # Start Gallery for testing
    just gallery
    # Or run a specific example
    just example hello_world
    

Step 1: Configure mcp.json for Local Development

Update ~/.codebuddy/mcp.json to use the local development version:

{
  "mcpServers": {
    "auroraview-dev": {
      "command": "vx",
      "args": [
        "uv",
        "--directory",
        "C:/Users/hallo/Documents/augment-projects/dcc_webview/packages/auroraview-mcp",
        "run",
        "auroraview-mcp"
      ],
      "env": {
        "AURORAVIEW_DEFAULT_PORT": "9222",
        "AURORAVIEW_PROJECT_ROOT": "C:/Users/hallo/Documents/augment-projects/dcc_webview",
        "AURORAVIEW_EXAMPLES_DIR": "C:/Users/hallo/Documents/augment-projects/dcc_webview/examples",
        "AURORAVIEW_GALLERY_DIR": "C:/Users/hallo/Documents/augment-projects/dcc_webview/gallery"
      }
    }
  }
}

Configuration Options

Variable Description Default
AURORAVIEW_DEFAULT_PORT Default CDP port for WebView 9222
AURORAVIEW_SCAN_PORTS Ports to scan (comma-separated) 9222,9223,9224,9225
AURORAVIEW_PROJECT_ROOT Path to project root Auto-detected
AURORAVIEW_EXAMPLES_DIR Path to examples directory Auto-detected
AURORAVIEW_GALLERY_DIR Path to Gallery directory Auto-detected
AURORAVIEW_DCC_MODE DCC mode (maya, blender, etc.) None

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.
