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.

Example request: "Check this week's duty status log for hours-of-service violations and tell me how much drive time the driver has left."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use X3 Compliance to help me. It is a free service with an MCP server at https://mcp.x3api.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
