Joey MCP Client

Joey MCP Client is an open-source AI chat app that lets you connect to any AI model through OpenRouter and extend those models with powerful tools and services.

Chat with any AI model

Access hundreds of leading AI models through OpenRouter, including GPT, Claude, Gemini, Deepseek and more. Joey connects via OAuth with configurable spending limits, so you stay in control of your usage — no surprise bills, no API keys to manage.

Connect your tools and services

Joey supports the Model Context Protocol (MCP), an open standard that lets AI models interact with external tools and services. Connect to multiple remote MCP servers simultaneously over HTTP, giving your AI conversations access to services like Google Drive, Slack, email, calendars, CRMs, and more.

Image support

Send images to vision-capable models directly from your camera, gallery, or clipboard. Great for asking questions about screenshots, documents, photos, and more.

Advanced MCP features

Joey goes beyond basic tool calling with support for advanced MCP capabilities:

▶ Sampling - MCP servers can request additional LLM completions, enabling complex multi-step AI workflows

▶ Elicitation - MCP servers can present interactive forms to gather input from you mid-conversation
