test-api-subprocess

test-api-subprocess is a command for Claude Code from SAGAAIDEV/mcp-ahrefs. It costs 10 tokens per session (1,050 once invoked), scanned A, original, MIT.

A command for comprehensive API testing through a Claude subprocess. An API is an interface that lets software communicate with another program.

In plain words
What is it for?
Use it to gather API details, inspect a Python backend, check the test environment, and run workflow tests with a Claude subprocess.
Why use it?
It helps investigate an API's structure and test expected, authentication, validation, integration, and error scenarios.

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-api-subprocess 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 3d 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.

I'll execute comprehensive API testing using a Claude subprocess for autonomous test execution.

Step 1: Prepare Test Context

Gather API Information

!echo "Current branch: $(git branch --show-current)" !find . -name ".py" -path "/routers/" -o -path "/endpoints/" -o -path "/controllers/" | head -10 !grep -r "@app." . --include=".py" | head -5 || grep -r "@router." . --include="*.py" | head -5

Check Test Environment

!test -f requirements.txt && grep -E "(pytest|httpx|requests)" requirements.txt !test -f .env.test && echo "Test environment file found" || echo "No test environment file"

Step 2: Determine Test Scope

Based on the feature and acceptance criteria:

  • API endpoints to test
  • Integration points
  • Authentication flows
  • Data validation rules
  • Error scenarios

Step 3: Launch Subprocess Testing

I'll execute the API tests using a Claude subprocess:

claude -p "You are testing a Python backend API. Your task is to:

1. Analyze the API structure in [PROJECT_PATH]
2. Test the following API workflow: [SPECIFIC_WORKFLOW_DESCRIPTION]
3. Create comprehensive test cases covering:
   - Happy path scenarios
   - Authentication and authorization
   - Input validation (edge cases, invalid data)
   - Error handling (4xx and 5xx responses)
   - Data persistence and retrieval
   - Integration with external services

4. For each endpoint test:
   - All HTTP methods (GET, POST, PUT, DELETE)
   - Query parameters and filters
   - Pagination if applicable
   - Request body variations
   - Header requirements

5. Test data scenarios:
   - Empty data sets
   - Single items
   - Large data sets
   - Special characters and Unicode
   - SQL injection attempts
   - Maximum field lengths

6. Performance considerations:
   - Response time for typical requests
   - Behavior under concurrent requests
   - Rate limiting if implemented

7. Create test files using pytest following the project structure
8. Run the tests and document results
9. Generate a coverage report

Use the following test patterns:
- Unit tests for business logic
- Integration tests for API endpoints
- Mock external services appropriately
- Use fixtures for test data setup

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.

test-api-subprocess is a command published in the GitHub repository SAGAAIDEV/mcp-ahrefs (0 stars, last pushed 1y ago), licensed MIT. It adds 10 tokens to every session and 1,050 once invoked, about $0.0001 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.
