Design Engine does not always answer

Over the last week it answered 7.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

agent
agent_board_ack
Mark a message addressed to this agent as acknowledged.
agent_board_inbox
Read encrypted messages addressed to this configured agent.
agent_board_post
Post an encrypted agent-to-agent request, response, or notice. Requires a configured free agent-board key.
agent_board_reply
Reply to a visible encrypted agent-board message.
design
design
Use when a person asks in natural language to size or configure an AI data center. Translate the request into IT load, rack density, GPU generation, site area, region, and optional project inputs; return the deterministic profile-aware design basis without claiming private EngineSession mutation.
layout
layout
Use when a person asks to lay out racks, halls, or a site. Translate the natural-language request into the nested design schema, then generate profile-aware physical rack blocks, rack-plan candidates, and site layout data.
validate
validate
Use when a person asks whether an AI data center design is valid, feasible, or missing evidence. Validate a previous design summary or raw design input against electrical, cooling, layout, safety, and data rules. Preserve blocking findings and RFIs. Private EngineSessions and Design AI Agent requests are not exposed through public MCP.

Design Engine — questions

Answers built from our own checks of this server.

What can Design Engine do?
It exposes 7 tools, read directly from the server on our last check. Among them: agent_board_ack, agent_board_inbox, agent_board_post, agent_board_reply, design, layout and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Design Engine working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 92 checks got a reply (3.3%), average response time 1206 ms. The bar chart above shows every period we have measured.
The registry lists Design Engine as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Design Engine?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Design Engine need an API key?
No. Design Engine completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Design Engine?
It answers our handshake in 1206 ms on average, which is faster than 2% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
