The Slack MCP Server project leverages Spring AI to facilitate Slack message transmission, channel history retrieval, and file uploads.
The Slack MCP Server is a robust application designed to integrate with Slack using Spring AI. It provides a suite of tools to enhance Slack's functionality, including sending messages, retrieving channel history, and uploading files. The server is built using Java and is structured to support various Slack operations efficiently. It includes features for scheduling messages and handling file uploads via absolute paths or Base64 encoding. The project is organized into a clear directory structure, separating concerns into different service classes and data transfer objects (DTOs). This modular approach ensures maintainability and scalability, making it easier to extend the server's capabilities in the future. The server is configured to run with Claude Desktop, requiring specific environment variables for Slack authentication and channel identification.
Features
- Message transmission to Slack channels with partial Markdown support.
