Sun

Sun MCP Server provides automated session summarization for Agent conversations. When you trigger its -sun command, it analyzes the current discussion, saves a structured summary as an .mdc file, and helps you review key points, outcomes, and next steps. It supports multiple languages, automatically saves summaries, and tracks completion status for each session.

How to use

You interact with Sun MCP Server through an MCP client. Start a session, then issue the -sun command to generate a summary in Chinese. Use -sun en to generate an English summary. You can provide context with a Chinese prompt like -sun 这次讨论了API开发 to create a Chinese summary with context. The tool automatically saves each summary as an .mdc file under a dedicated .sun folder and organizes information by date and function.

Key benefits you get from Sun MCP Server include a structured overview of the conversation, extraction of core ideas and key points, automatic status detection (completed/partial/failed/ongoing), and easy access to historical summaries.

How to install

Prerequisites: ensure you have Node.js and npm installed on your machine.

# Quick install via npx (recommended)
npx -y sun-mcp@latest

If you prefer manual configuration in your client, add the MCP server entry below to your client configuration and restart your client.

{
  "mcpServers": {
    "sun-mcp": {
      "command": "npx",
      "args": ["-y", "sun-mcp@latest"]
    }
  }
}

Notes and configuration tips

After configuration, you can restart your MCP client to load the Sun MCP Server. The summaries are stored in a .sun folder under the project root with filenames that include the date and function name, for example: 20241208_143022_MCP服务器开发.mdc.

Additional usage tips

• Use -sun to generate Chinese summaries and -sun en to generate English summaries. -sun 这次讨论了API开发 provides context-rich Chinese output.

• The server outputs a structured summary that includes the session overview, core essence, key points, completed outcomes, and suggested next steps.

Troubleshooting

If you encounter issues starting the MCP server, verify that Node.js and npm are installed, the npx command is accessible, and you have network access to fetch sun-mcp@latest. Check that the .sun folder is writable and that your client has the sun-mcp server configured.
