Checks trucking, workplace safety and maritime rules against the cited federal regulation
Pulls from the official eCFR, FMCSA, OSHA, PHMSA and Coast Guard sources. Muse can check hours-of-service logs, decide whether an injury belongs on the OSHA 300 Log, look up CFR text, work out 811 dig timing, and review driver qualification files, citing the rule each time.
Try asking Muse: "Check this week's duty status log for hours-of-service violations and tell me how much drive time the driver has left."

X3 Compliance 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 (November 14, 2026, 15:06 UTC) the endpoint was working, answering in 58ms. It is checked every 15 minutes.
It was screened on November 14, 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 20 tools, including hos_check, osha_is_recordable, osha_coverage, osha_rates. For example, you could ask Muse: "Check this week's duty status log for hours-of-service violations and tell me how much drive time the driver has left."
