Research which regulations may apply to your product across jurisdictions and industries.
Magist provides deterministic regulatory research for product launches. Search regulations by keyword and jurisdiction, compute which rules may apply based on your product features and target markets, find compliance controls and vendors, and review enforcement history. Returns research information only; consult a lawyer for legal advice.

Magist is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.

At the last check (October 29, 2026, 09:15 UTC) the endpoint was working, answering in 1130ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
It was screened on October 28, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 9 tools, including lookup_regulation, search_regulations, compute_requirements, find_controls. For example, you could ask Muse: "Tell me which regulations might apply if I launch a social app targeting teens in the EU and US."
