Slack MCP Server Architecture

This section provides comprehensive documentation of the Slack MCP Server architecture, covering all major components and their interactions.

Architecture Components

The Slack MCP Server is built with a modular architecture that supports multiple deployment modes and integration patterns:

🏗️ Project Structure

  • Overall source code organization
  • Design patterns and principles
  • Directory structure and key components
  • Development workflow and conventions

🔧 MCP Server Architecture

  • Model Context Protocol implementation
  • Transport mechanisms (stdio, SSE, HTTP)
  • Tool registration and execution
  • Client communication patterns

🌐 Webhook Server Architecture

  • FastAPI-based webhook server
  • Slack event processing
  • Queue integration and event publishing
  • Security and authentication

Integrated Server Architecture

  • Combined MCP and webhook server deployment
  • Unified FastAPI application
  • Transport configuration options
  • Production deployment patterns

System Overview

Key Features

  • Multiple Transport Options: stdio, Server-Sent Events (SSE), and HTTP streaming
  • Flexible Deployment: Standalone MCP server, standalone webhook server, or integrated mode
  • Event Processing: Asynchronous Slack event handling with queue integration
  • Security: Request signature verification and token management
  • Scalability: Horizontal scaling support for webhook processing

Design Principles

  1. Modularity: Clear separation between MCP and webhook functionality
  2. Extensibility: Easy to add new MCP tools and event handlers
  3. Security: Secure token handling and request verification
  4. Performance: Asynchronous processing and efficient resource usage
  5. Reliability: Robust error handling and recovery mechanisms
