Give your AI the rule book.

A free MCP server that lets Claude, ChatGPT, Cursor and VS Code check hours of service and driver files, explain CSA scores, decide OSHA recordability, read safety data sheets, time an 811 ticket, compute pipeline MAOP, check mariner rest hours, quote any federal regulation and pull a vessel's Coast Guard record. Every answer comes from the rule text or official government data, with the citation.

Then ask

"Here's my driver's log for Monday and Tuesday. Any hours-of-service violations?"
"An employee got 4 stitches and was back the next day. Is it OSHA recordable?"
"We called in an 811 ticket in Ohio at 3 p.m. Monday. When can we dig?"
"Quote 49 CFR 192.605(b), and what changed in Part 192 since 2024?"
"Do we have to file our 300A with OSHA? NAICS 484121, 120 people at this terminal."
"Is the Certificate of Inspection current for this vessel?"
