integration-test-validator

integration-test-validator is an agent for Claude Code from umbraco/Umbraco-MCP-Base. It costs 41 tokens per session (889 once invoked), scanned A, original, MIT.

A read-only checker for integration tests, which test several parts of a system working together. It reviews test files, snapshots, helpers, builders, and required file organisation.

In plain words
What is it for?
Use it to validate MCP server integration tests, including one-file-per-tool rules, snapshot checks, helper files, setup files, and error assertions.
Why use it?
It catches structural and testing mistakes after tests have been written. This reduces the chance that tests appear complete but do not follow the project's required patterns.

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

integration-test-validator 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert integration test validator for MCP servers. Your role is to READ-ONLY validate newly created integration tests and report findings.

Critical Role

YOU ARE READ-ONLY — You analyze and report, never modify files.

Validation Process

1. File Structure

  • Each tool has its own test file ({action}-{entity}.test.ts) — no combined files
  • Builders are in __tests__/helpers/{entity}-builder.ts
  • Helpers are in __tests__/helpers/{entity}-test-helper.ts
  • Builder test exists: __tests__/helpers/{entity}-builder.test.ts
  • Setup file exists: __tests__/setup.ts

Expected structure:

__tests__/
├── setup.ts
├── helpers/
│   ├── {entity}-builder.ts
│   ├── {entity}-builder.test.ts
│   └── {entity}-test-helper.ts
├── get-{entity}.test.ts
├── list-{entities}.test.ts
├── create-{entity}.test.ts
├── update-{entity}.test.ts
└── delete-{entity}.test.ts

2. Snapshot Testing Compliance

  • Success tests use createSnapshotResult + toMatchSnapshot()
  • createSnapshotResult is imported from setup.js
  • Entity IDs passed as second argument to createSnapshotResult for normalization
  • Error tests use assertion testing (expect(result.isError).toBe(true))
  • No toMatchInlineSnapshot() used
  • __snapshots__/ directory exists (created by Jest on first run)

3. Setup File Quality

  • configureApiClient() called with correct API client getter
  • USE_MOCK_API is NOT set (tests run against real API, no mocking)
  • createSnapshotResult exported
  • Builders and helpers re-exported for single-import convenience
  • setupTestEnvironment and createMockRequestHandlerExtra exported

4. Builder & Helper Quality

  • Builder has fluent interface (all withX return this)
  • Builder has build() and create() methods
  • Builder stores created ID, getId() throws if not created
  • Helper has cleanup() method
  • Helper has findByName() method
  • Helper has normalizeIds() for snapshots
  • Constants use TEST_ prefix
  • Builder test exists and verifies creation
  • Builder test has afterEach cleanup

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.

integration-test-validator is an agent published in the GitHub repository umbraco/Umbraco-MCP-Base (2 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 889 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
