When we introduced Decree MCP in May, it let you connect Claude and other AI tools to Decree’s English legislation database, so that the answers you got were grounded in real Omani law rather than the model’s guesswork. Today we’re releasing its successor, and it is a considerable step up.
The new MCP server covers Decree’s Arabic collection alongside the English one. Answers are no longer limited to what we have translated into English, and material that exists only in Arabic is now within reach, including the full text of MJLA fatwas. You no longer need to think about the language of the source. Claude and other tools will search our database in both Arabic and English and answer you in the language you are working in.
The new server is also far better at knowing which version of a law matters. It tells Claude whether an instrument is still in force, has been repealed, or has a consolidated version that supersedes it, so the answer you get quotes the text that actually applies today.
Connecting Decree MCP to Claude
Open Claude, either the desktop app or claude.ai, and go to Settings, then Connectors. Choose “Add custom connector” and paste in https://mcp.decree.om/. Claude will ask you to sign in: use the email address on your Decree account, and we’ll send you a six-digit code to confirm it.
From then on, just ask your legal questions as you normally would. Claude will search Decree on its own when a question calls for it. Try “Is the Omani Labour Law still current, and what changed?” to see it work.
If you set up Decree MCP after our May announcement, you will have a connector pointing at mcp-lr.decree.om. Please delete it. Leaving both in place means your assistant sees two sets of Decree tools and may keep reaching for the older one, which searches only the English collection and does not track amendments using our new smarter logic. In Claude, go to Settings, then Connectors, find the old Decree entry, and remove it before or after adding the new one.
Access is available to Decree members whose subscription includes Lex AI.
