Onesauce MCP is a standard remote MCP server. It uses the Streamable HTTP transport and OAuth sign-in:
Onesauce MCP URL
Claude and ChatGPT work for every organization. Other clients, such as Cursor or an internal agent platform, work only if your organization allows them. Ask your Onesauce admin or your Onesauce contact to enable the client you want to use.

Connecting a client

Most MCP clients need only the URL. The client finds the sign-in server on its own and opens the Onesauce sign-in page. For example, in Claude Code:
Then run /mcp in Claude Code and choose Onesauce to sign in.

Requirements for the client

  • Remote MCP over Streamable HTTP. Clients that only support local (stdio) servers can’t connect directly.
  • OAuth 2.1 with PKCE, with discovery through the server’s protected-resource metadata.
  • Scopes: the client must request the scopes listed under Security. Tools that need a missing scope are refused.
