Anthropic introduces the Model Context Protocol
Anthropic announced the Model Context Protocol on 25 November 2024. MCP is an open standard intended to reduce the number of one-off integrations between AI assistants, data sources and tools.
What MCP is
MCP defines a shared way for applications to expose context and tools to AI systems. Anthropic released specifications, SDKs and reference servers as part of the announcement.
Why it matters
A common interface can make integrations easier to maintain and replace. For companies, the potential benefit is less custom glue code between assistants, repositories, databases and internal tools.
What remains your responsibility
A protocol does not decide who may access which data or execute which action. Authentication, least-privilege permissions, approval gates and audit logs still have to be designed explicitly.
