### Description (declared)

# apibench-mcp

A Model Context Protocol (MCP) server for REST and SOAP API testing. Supports HTTP requests, SOAP calls, response assertions, request chaining, data-driven load testing, and response storage.

## Overview

apibench-mcp provides a structured set of tools for API testing through MCP-compatible AI clients. It is designed for both functional testing (individual requests with assertions) and performance testing (concurrent load with statistics).

Key capabilities:
- REST requests with authentication, custom headers, and JSONPath extraction
- SOAP requests via WSDL with XPath extraction
- Flag-based response assertions (status code, headers, body content, JSONPath)
- Sequential request chaining with value injection from prior responses
- Data-driven load testing with CSV, JSON, or DSV data files
- System resource preflight checks before load testing
- In-memory response storage with file export

## Installation

```bash
pip install apibench-mcp
```

## Usage

```bash
apibench-mcp
```

The server requires no arguments. It starts and exposes its tools over the MCP protocol.
