MCP's Disregard for 40 Years of RPC Best Practices

- MCP (Model Context Protocol) overlooks 40 years of RPC best practices, risking enterprise deployments.
- MCP prioritizes simplicity over operational robustness, creating potential production failures.
- MCP lacks type safety, using schemaless JSON without enforced validation, leading to runtime errors.
- MCP ignores lessons from UNIX RPC, CORBA, REST, SOAP, and gRPC, missing critical features like type safety, observability, and security.
- MCP's design leads to fragmentation, relying on third-party libraries for essential features like authentication and tracing.
- MCP's recent updates (OAuth support, tool annotations) reveal premature release and lack of enterprise readiness.
- MCP lacks distributed tracing, cost attribution, and service discovery, hindering debugging and scalability.
- MCP's text-based protocol and lack of binary options create performance bottlenecks for high-throughput systems.
- Enterprises deploying MCP in critical systems (finance, healthcare) face risks due to its immature design.
- MCP must adopt proven patterns (type safety, tracing, versioning) to avoid fragmentation and operational failures.
