MCP protocol presents complexity, security, and documentation issues

The ask

Developers using the MCP protocol frequently encounter difficulties. The existing standard is perceived as overly complex and includes an unnecessary middleware server component. Furthermore, the protocol has various security vulnerabilities. These flaws suggest the standard might have been implemented without adequate review, making it less reliable for current development needs. Another significant hurdle is the poor state of its documentation. Users find the available information confusing and insufficient, leading to increased development time and frustration. A clearer, more secure, and better-supported alternative would greatly benefit developers working with this standard.
