MCP stands for Model Context Protocol. It is an open-source standard created to help AI models securely connect to external tools, data sources, and software systems.

Most engineers using MCP can't explain what's actually happening on the wire.

They've cloned a repo, run a server, watched it work. Ask what `initialize` does, or why the token bill quietly doubled after they added a few servers, and the conversation gets short.

So I mapped the entire protocol. One image. Save it.

𝗪𝗵𝘆 𝗶𝘁 𝗲𝘅𝗶𝘀𝘁𝘀
Before MCP: N models × M tools = a custom bridge for every pair.
With MCP: N + M. One protocol in the middle.

𝗧𝗵𝗲 𝘁𝗵𝗿𝗲𝗲 𝗿𝗼𝗹𝗲𝘀
Host is the app you use. Client lives inside the host. Server is your code, exposing capability.
Underneath: JSON-RPC 2.0. Nothing exotic.

𝗧𝗵𝗲 𝘁𝗵𝗿𝗲𝗲 𝗽𝗿𝗶𝗺𝗶𝘁𝗶𝘃𝗲𝘀
Tools — model-controlled. The AI decides when to call.
Resources — app-controlled. The app pushes context.
Prompts — user-controlled. The user invokes them.

𝗧𝗵𝗲 𝗽𝗮𝗿𝘁 𝗻𝗼𝗯𝗼𝗱𝘆 𝘁𝗮𝗹𝗸𝘀 𝗮𝗯𝗼𝘂𝘁
Every tool schema travels in every LLM call. 50 tools = 50 schemas, every turn.
OAuth across many servers becomes real secret rotation work.
Tool sprawl is the new microservices sprawl.
Schema drift breaks agents silently.

MCP isn't a framework. It's a protocol. Mental model is HTTP, not LangChain. Boring, foundational, slowly everywhere.

Save the graphic for the next time someone asks how MCP actually works.

Underneath this giant rock (Chincana Grande) there is believed to be an entrance into a vast and ancient labyrinth.

The stone itself shows one example after another of surgical levels of precision removal, for reasons we don't understand.

So I travelled to Peru to show you.

AI isn't going to kill tech jobs - it is going to redistribute them - we already seeing it. Net technical hiring is projected to increase 31% in 2026. Companies are prioritizing upskilling over external hiring. - LIVE from #OSSummit in Minneapolis

By my read, the two documents: “USPER STATEMENT ABOUT UAP SIGHTING” and “WESTERN US EVENT” appear related.

The UFO data drop might be a vanilla, low-signal test to gauge the public. But the Pentagon endorsing inquiry into astronaut UFO sightings while NASA continues to play dumb is a big deal. How can you definitively debunk cases NASA itself was baffled by? Apollo 17👇

Astrophysicists have found evidence of UAPs in old photographic plates. Something seems to have been orbiting around our planet before we had satellites! This finding has been independently confirmed. Still, scientists are afraid to speak out. @DrBeaVillarroel @Rizstanford

Under the directives of the President of the UAE, we launch a new government model. Within two years, 50% of government sectors, services, and operations will run on Agentic AI, making the UAE the first government globally to operate at this scale through autonomous systems.

AI is no longer a tool. It analyses, decides, executes, and improves in real time. It will become our executive partner to enhance services, accelerate decisions, and raise efficiency.

This transformation has a clear timeline. Two years. Performance across government will be measured by speed of adoption, quality of implementation, and mastery of AI in redesigning government work.

We are investing in our people. Every federal employee will be trained to master AI, building one of the world’s strongest capabilities in AI-driven government.

Implementation will be overseen by Sheikh Mansour bin Zayed, with a dedicated taskforce chaired by Mohammad Al Gergawi driving execution.

The world is changing. Technology is accelerating. Our principle remains constant. People come first. Our goal is a government that is faster, more responsive, and more impactful.

If the government wants to read your emails, it should have to convince a judge first. That's what the Fourth Amendment requires. That's what my Fourth Amendment Restoration and Protection Act restores. No warrant, no search.
