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

There are two types of API keys, and the available tools depend on which ones you configure:

• MOCKFLY_ACCOUNT_API_KEY (account API key) — enables the project tools (create, import, update and delete projects). Create yours at https://app.mockfly.dev/api-keys. The full key is only shown once at creation time.
• MOCKFLY_API_KEY (project API key) — enables the endpoint and response tools for a specific project. You can find it in https://app.mockfly.dev by clicking on the configuration button of your project.

You can set one or both. At least one is required.
