AI infrastructure, made legible
MCP Control Room
Model Context Protocol is the standard layer between an AI host app and the tools it can actually use. This demo shows the full chain: request, tool discovery, server call, structured result, grounded answer.
- Tool discovery
- Structured I/O
- Permission boundary
- Grounded answers

The product surface
Claude Desktop, Codex, Cursor, or your own product can all be the host. The host manages which servers exist, what the model is allowed to call, and how results are displayed to the user.
MCP server
The tool gateway
An MCP server is just a standard bridge around some capability: filesystem access, GitHub, calendar, docs, search, or anything custom your team exposes.
Why the protocol matters
Less glue, more leverage
Without a standard protocol, every host app and every integration invents its own contract. MCP makes those integrations legible, reusable, and easier to inspect.
