Many Gateways popping up now, im also doing my own gateway (https://mcp-boss.com/) but im starting to worry its hard to compete with Docker, Microsoft, now IBM...
mcp is not the future IMO, agent2agent is, e.g. a2aproject/A2A
The problem with MCP is that it cannot reliably scale, so some abstraction is helpful, i.e. separate “agent” with its own instructions and a predefined set of tools.
