The connection uses MCP, an open standard that most AI apps support. Claude acts as you and sees exactly what you can see in Loctax, nothing more. You don't need an API key.
1. Copy the URL in Loctax
Open the organization menu, select My profile, then Assistant external access. On the MCP tab, select Copy URL.
2. Add it to Claude
In Claude's settings, under Customize, open Connectors.
Select Add, then Add custom connector.
Name it Loctax, paste the URL and select Continue.
Keep the default sign-in settings and select Add.
3. Connect and confirm in Loctax
Select Connect.
Loctax asks you to confirm: select Continue, check the organization and select Allow access. Claude now shows Loctax as connected.
Good to know
In Loctax, the app shows under Your connected apps, with the date it was last used. Select Disconnect to end its access at any time.
For Claude Code, copy the command shown on the page.
Tools that can't sign in, such as Cursor, need a personal API key from the API tab. Keep that key out of shared files.
ChatGPT, Copilot and other AI apps that support MCP connect the same way: the same URL and the same Loctax sign-in.
