What is Model Context Protocol? A practical guide to MCP - Cohere
Summary
Model Context Protocol (MCP) is an open standard designed to bridge the gap between AI applications and authorized enterprise systems. It enables AI applications to access data and perform defined actions across various external platforms, including databases, document repositories, and business applications, by reducing the need for custom integrations. MCP operates via a client-server architecture where an AI application acts as a host, connecting to multiple MCP servers through clients. These servers expose three main features: resources for contextual information, tools for defined functions like API calls, and prompts for structured interactions. While distinct from APIs, RAG, function calling, and agents, MCP complements them by standardizing how AI applications discover and utilize external capabilities. Common enterprise use cases span customer support, sales, financial reporting, and IT incident management. Implementing MCP requires careful security considerations, including robust access control, authentication, authorization, and monitoring, as it is not inherently secure.
Key takeaway
For AI Architects evaluating enterprise AI integration strategies, MCP offers a standardized approach to connect AI applications with critical business systems. You should prioritize robust access control, authentication, and monitoring when deploying MCP servers to mitigate security risks. This protocol simplifies extending and maintaining AI applications, but your team must actively design and implement governance policies for secure, scalable operations.
Key insights
Model Context Protocol (MCP) standardizes AI application integration with enterprise systems for data access and action execution.
Principles
- MCP is an integration protocol, not a model or agent.
- Security is configured, not inherent, in MCP deployments.
- Standardized integration improves AI application maintainability.
Method
MCP employs a client-server architecture where AI applications (hosts) connect to MCP servers via clients. Servers expose resources, tools, and prompts for AI applications to utilize.
In practice
- Use MCP for AI access to CRM, ERP, or document stores.
- Implement least-privilege access for MCP server capabilities.
- Require human approval for sensitive MCP-driven actions.
