Model Context Protocol (MCP): Open standard connecting AI to external systems

ArticleResource

The Model Context Protocol (MCP) is an open-source standard connecting AI applications such as Claude or ChatGPT to data sources, tools, and workflows. It acts as an open, universal interface akin to a USB-C port for AI systems.

Key points

  1. MCP standardises how AI models interface with local files, databases, search engines, and prompt workflows.
  2. Practical use cases include assistants interacting with Google Calendar and Notion, Claude Code building web apps from Figma designs, and enterprise chatbots querying databases.
  3. For developers, MCP lowers integration complexity through a 'build once, integrate everywhere' approach.
  4. Broad ecosystem adoption covers clients and developer tools including Claude, ChatGPT, Visual Studio Code, Cursor, and MCPJam.
  5. Development revolves around building MCP servers to expose tools/data, client applications, and embedded MCP apps.

Why it matters

Fragmented, proprietary integrations between AI models and internal systems lead to redundant engineering work. MCP provides a shared standard, enabling modular, vendor-agnostic tool use and context retrieval.

Analysis

The documentation frames MCP as an open foundation for agentic workflows. Support across both major AI assistants and code editors like Cursor and VS Code makes it straightforward for teams to build interoperable connectors for their internal APIs and databases.
