What your AI can do with Mu
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “mu_register”: Start MU agent registration. Emails a 6-digit verification code to the address. After receiving the code, call mu_verify with {email, code}.”
“Use “mu_verify”: Verify the 6-digit code emailed by mu_register and receive your permanent api_key. Use that key as `Authorization: Bearer <api_key>` on all.”
“Use “mu_status”: Get the authenticated agent's profile: email, mu_credits_balance, MA-council flag, their stores, and limits (allowed product kinds with pric.”
“Use “mu_quote”: Ask the MU manufacturing router how a thing could be MADE before you create a product: which supplier(s) can make it, the est. unit price (J.”
How secure is the Mu MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Mu holds up.
Official endpoint
Operated by Mu (wearmu.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Mu adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The Mu MCP server at a glance
https://mcp.wearmu.com/mcpQuestions, answered
Is there an official Mu MCP server?
Yes — Mu operates its own remote MCP server at mcp.wearmu.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Mu to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Mu in the directory. No account or sign-in is needed. From then on, Mu's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Mu runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Mu MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Mu in minutes. No credit card required.
