Dev Proxy MCP Server

A Model Context Protocol (MCP) server for Dev Proxy that enables AI assistants to interact with Dev Proxy capabilities using the MCP standard. Use this server to:

1. Create Dev Proxy configurations using natural language
2. Get contextual help for working with Dev Proxy
3. Discover Dev Proxy features and capabilities

What is Dev Proxy?

Dev Proxy is an API simulator that helps you effortlessly test your app beyond the happy path. It allows you to:

• Test API error handling: See how your app responds to API errors without changing your code
• Verify rate limit handling: Simulate API rate limits to improve user experience
• Test slow API responses: See how your app handles slow APIs to implement necessary affordances
• Create mock APIs: Quickly stand up mock APIs without writing code you won't ship

Dev Proxy works with any type of app and tech stack as it intercepts network requests at the proxy level.
