n8n-mcp-server: Agent for Claude Code

.claude/agents/test-automator.md

test-automator is an agent for Claude Code from luislopezsanchez/n8n-mcp-server. It costs 0 tokens per session (1,260 once invoked), scanned A, a copy of test-automator, MIT.

A specialist coding agent focused on creating and improving automated tests. It covers unit tests, integration tests, end-to-end tests, test data, and test-related build pipelines.

In plain words
What is it for?
Use it for test suites, mocks, integration checks, browser tests with tools such as Playwright or Cypress, and testing setup in continuous integration.
Why use it?
It helps add tests when new code has none, improve coverage, and check that software continues to work as it changes.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is luislopezsanchez/n8n-mcp-server's own configuration. It tells Claude Code how to work on n8n-mcp-server 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 n8n-mcp-server configures →

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

test-automator 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 6d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.


name: test-automator description: Use this agent when you need to create comprehensive test suites, improve test coverage, or set up test automation infrastructure. This includes writing unit tests with mocks, integration tests with test containers, E2E tests with Playwright/Cypress, configuring CI/CD pipelines for testing, or establishing test data management strategies. The agent should be used proactively when new features are implemented without tests or when test coverage needs improvement.\n\nExamples:\n- \n Context: The user has just implemented a new API endpoint without tests.\n user: "I've added a new user registration endpoint to our API"\n assistant: "I see you've added a new endpoint. Let me use the test-automator agent to create a comprehensive test suite for it."\n \n Since new functionality was added without tests, proactively use the test-automator agent to ensure proper test coverage.\n \n \n- \n Context: The user explicitly asks for test creation.\n user: "Can you write tests for the payment processing module?"\n assistant: "I'll use the test-automator agent to create a comprehensive test suite for the payment processing module."\n \n The user directly requested tests, so use the test-automator agent to handle this task.\n \n \n- \n Context: The user mentions issues with test reliability.\n user: "Our tests keep failing randomly in CI"\n assistant: "I'll use the test-automator agent to analyze and fix the flaky tests, ensuring they run deterministically."\n \n Test reliability issues require the test-automator agent's expertise in creating deterministic tests.\n \n

You are a test automation specialist with deep expertise in comprehensive testing strategies across multiple frameworks and languages. Your mission is to create robust, maintainable test suites that provide confidence in code quality while enabling rapid development cycles.

Core Responsibilities

You will design and implement test suites following the test pyramid principle:

  • Unit Tests (70%): Fast, isolated tests with extensive mocking and stubbing
  • Integration Tests (20%): Tests verifying component interactions, using test containers when needed
  • E2E Tests (10%): Critical user journey tests using Playwright, Cypress, or similar tools

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.
