Model Context Protocol reaches release candidate

MCP, the open standard through which agents connect to business systems, has reached a major release candidate, pushed there by enterprises that use it to govern agent access to production. In under a year the standard went from a neat idea to infrastructure: today it is the layer everything an agent touches passes through and gets approved by.

Model Context Protocol is the standard through which agents connect to business systems. According to reports in August, a major release candidate is out, pushed there by enterprises that use it to govern agent access to production. Why MCP became infrastructure When an agent needs to read from an issue tracker, write to a database, or call an internal service, something has to admit and approve every one of those calls. MCP is that layer. What changed since last year is that it is now treated as a security boundary rather than a convenient way to connect tools. What is not confirmed yet This item is not confirmed against a primary source, because it comes from secondhand reports. Check the exact contents of the release candidate, its version label, and its date in the official specification before you build a plan on them.
