MCP Faces Security and Context Window Challenges
At the London Model Context Protocol (MCP) conference last week, developers and vendors discussed rising security and context-window challenges when connecting LLMs to external tools. Speakers highlighted OAuth 2.1-based authorization complexities, progressive-disclosure patterns to limit tool context, and the emergence of ChatGPT apps with payment friction; practical advice included starting with a single read-only internal MCP server and limited user testing. These issues affect enterprise MCP adoption and deployment timelines.
