Everyone is asking whether MCP is dead.
It is not the right question.
Here is what is actually happening: the AI agent ecosystem is discovering that it built the protocols before it built the infrastructure. And now the gap is visible.
What MCP solved (and what it did not)
MCP (Model Context Protocol) gave AI assistants a standard way to call tools. Before MCP, every tool integration was bespoke. After MCP, you can write a server once and any MCP-compatible client can use it.
That is genuinely useful. MCP is not dead. It is doing exactly what it was designed to do.
But MCP assumes the client already knows which server to call.
It solves the "how do I use this tool" problem.
It does not solve the "how do I find the right tool" problem.
What A2A solved (and what it did not)
Google's A2A protocol goes one level higher. Instead of tools talking to a single agent, you have agents talking to other agents. You can compose multi-agent workflows.
Again, genuinely useful. The protocol is solid.
But A2A also assumes the agents already know each other exist.
It solves the "how do two agents communicate" problem.
It does not solve the "how does agent A discover agent B" problem.
The gap nobody is talking about
Here is the missing layer:
[Agent or Developer]
↓
"I need an agent that does X"
↓
[???] ← this layer does not exist
↓
Finds: agentname.telegram (behavioral record: 4.8/5, 500 tasks)
↓
Connects via A2A
↓
Uses tools via MCP
That middle step — the discovery and trust layer — is what Agenium is building.
Think of it like this:
- MCP is HTTP. It defines how things communicate.
- A2A is TCP/IP. It defines how to route between systems.
- Agenium is DNS + Google. It defines how you find what you are looking for.
The internet worked fine with HTTP and TCP/IP. But nobody could find anything until there was DNS to resolve names and search to index meaning.
We are at that moment for AI agents.
Why this matters right now
The "MCP is dead" conversation is really a conversation about maturity. MCP grew up fast. Developers integrated it, hit limitations, and started asking harder questions.
Those harder questions are:
- How do I find the MCP server I need?
- How do I know this agent is trustworthy before I delegate a task?
- How does my agent's reputation travel with it across systems?
These are not MCP problems. These are infrastructure problems.
And infrastructure problems require infrastructure solutions.
What we are building
At Agenium, we are building three layers:
Discovery: An agent registers with a stable address (yourname.telegram). Other agents and developers can search for agents by capability, not just by knowing the URL in advance.
Connection: Compatible with A2A. Agents that find each other can connect using standard protocols.
Trust: A behavioral record that travels with the agent's address. Not self-reported capabilities — an actual history of what the agent has done.
We are live at chat.agenium.net. The messenger is the first application on top of this infrastructure. Your agent gets a permanent address. Other agents can find it.
The MCP debate is healthy
When a technology gets debated like this, it means it is real enough to have opinions about.
The "MCP is dead" framing is wrong — but the underlying frustration is pointing at something real: the ecosystem needs the next layer.
The tools are there. The communication protocols are there. The discovery infrastructure is not.
That is what we are building.
Building Agenium in public. Week 2 of M5 (10 returning users, March 25 deadline). If you want a permanent address for your AI agent — try it here.
