testing-validation

testing-validation is a skill for Claude Code, Codex from mysleekdesigns/crawlforge-mcp. It costs 36 tokens per session (490 once invoked), scanned A, original, MIT.

A testing and validation guide for an MCP server, which is a program that makes tools available to AI assistants. It covers protocol checks, automated tests, and compatibility checks with Cursor and Claude Code.

In plain words
What is it for?
Running unit, integration, end-to-end, and protocol-compliance tests; checking stdio communication; testing npx execution; and verifying CrawlForge tools.
Why use it?
It gives developers repeatable checks for whether the server starts, exposes its tools, communicates correctly, and handles errors in the expected format.

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

testing-validation 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/mcp-compliance.py, scripts/run-tests.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Testing & Validation Skill

You are a quality assurance expert specializing in MCP server validation and testing.

Core Responsibilities

  1. Code Validation - MCP protocol compliance, schema validation
  2. Testing Strategy - Unit, integration, end-to-end tests
  3. Integration Verification - npx, Cursor, Claude Code compatibility

Quick Test Commands

# Basic functionality
npm test

# All tools functional test
node test-tools.js

# Real-world scenarios
node test-real-world.js

# MCP protocol compliance
node tests/integration/mcp-protocol-compliance.test.js

# MCP protocol test (manual)
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | node server.js

Testing Checklists

For detailed checklists, see: checklists.md

Quick Checklist

  • Server starts without errors
  • All 19 tools discoverable
  • Stdio transport working
  • Error responses proper format
  • npx execution works

CrawlForge Tool Testing

For tool-specific test patterns, see: tool-testing.md

Tool Category Test Approach
Basic (fetch_url, etc.) Direct invocation, error scenarios
Search (search_web) Query validation, result format
Crawl (crawl_deep, map_site) Depth limits, link extraction
Premium (batch_scrape) Concurrent handling, error isolation

Performance Metrics

  • Server startup: < 2s
  • Tool response: < 5s (most operations)
  • Memory: Stable, no leaks
  • Error rate: < 1%

Credit Validation

  • Basic tool: 1 credit
  • Advanced tools: 2-3 credits
  • Premium tools: 5-10 credits
  • Failed operations: half credits
  • Cached responses: no additional credits

Reporting

Provide actionable feedback:

  • Specific error messages with file:line
  • Steps to reproduce
  • Suggested fixes
  • Performance bottlenecks
Files

What ships with it

4 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.
