Mockfly MCP Client

An MCP (Model Context Protocol) server for managing your Mockfly projects, mock endpoints and responses.

Features

• Create, import, update and delete projects
• List all mock endpoints
• Get endpoint details
• Create and edit endpoints
• Manage mock responses (create, edit, duplicate, delete)
• Manage conditional rules for responses

Installation

Globally via npm

npm install -g mockfly-mcp-client

Configuration

The server needs a single environment variable, MOCKFLY_API_KEY, with your account API key (mf_…). It gives access to every project you are a member of. Create yours at app.mockfly.dev/api-keys. The full key is only shown once at creation time.
