NextChat is a flexible open-source AI chat client that supports multiple models and cross-platform deployment. However, it is not an official MCP server, and users must pay attention to security configuration.
NextChat is a cross-platform AI chat client that runs on Web, iOS, macOS, Android, Linux, and Windows. It supports multiple AI model providers, including OpenAI GPT-4, Anthropic Claude, Google Gemini Pro, DeepSeek, and more. NextChat prioritizes privacy by storing all data locally in the browser. MCP functionality can be enabled via the environment variable ENABLE_MCP=true.
Tools
The tool list has not been reviewed yet.
Setup
- Get an OpenAI API key (optional).
- Deploy with one click on Vercel or run locally (requires Node.js >= 18).
- To enable MCP, set the environment variable ENABLE_MCP=true and then start the application.
Fit and risk
Not for
- Production-grade AI services requiring official support
- Non-technical users looking for a ready-to-use AI service (may require configuration)
- Enterprises with strict data governance requirements (data is stored locally in the browser by default)
Required permissions
- Network access to call AI model APIs
- Local storage in the browser (e.g., chat history, settings)
- When using MCP, may connect to local or remote tools
Risks and side effects
- This server is not an official product but a community-maintained open-source project, which may be less stable than official versions.
- If self-hosted, API key security is crucial and must be protected.
- Relying on third-party deployment services (e.g., Vercel) may introduce data security risks.
- Enabling MCP features increases the attack surface.
Troubleshooting
- If API calls fail, check BASE_URL and API key configuration.
- If the page is inaccessible, check the environment variable CODE (acts as an access password).
- If MCP is not effective, confirm ENABLE_MCP=true is set and restart the application.
Use cases
Chatting via a web or desktop interface
