How does MCP shift the integration burden away from your own server?

MCP moves tool definitions and execution from your own server to dedicated MCP servers. Instead of writing every GitHub integration yourself, you connect to an MCP server for GitHub that already wraps GitHub's functionality and exposes it as a standardized set of tools. Your application talks to that MCP server instead of implementing everything from scratch. The MCP server handles all the service-specific implementation details, while your code only needs to know how to communicate using the protocol. The benefit is clear: instead of maintaining a complex set of integrations yourself, you can leverage MCP servers that handle the heavy lifting of connecting to external services.
