Guide to understanding MCP with examples

Model Context Protocol (MCP) is a standardized protocol that facilitates the integration of AI applications, such as ChatGPT and Claude, with external systems like CRM tools or other services, enabling users to perform complex operations through AI clients by exposing functions called "tools." This standard allows AI to interact with your product's APIs and conduct tasks on behalf of users, like querying CRM data or integrating with services such as Crunchbase or Gmail for enhanced workflows. MCP servers can operate locally or remotely, with local servers interacting directly with the user's machine and remote servers often requiring authentication via OAuth 2.1 to ensure secure operations. The protocol's design allows multiple AI clients to understand and interact with an MCP server, promoting interoperability and enabling seamless, multi-system operations. PropelAuth offers a service to handle authentication complexities, allowing developers to focus on implementing core functionalities like search or update actions without dealing with the intricacies of login, consent, and token management.
