+==== Stages permissions ====
+The MCP integration acts on behalf of the authenticated user. In addition to the usual permissions to view workspaces and process elements, the user must have the MCP permission to access them through MCP.
+To let all users use MCP, add the MCP domain to the default group.
+==== MCP client configuration ====
+Configure your MCP client to connect to the Stages MCP server at this URL:
+''<nowiki>https://stages.example.com/stages/api/1/mcp</nowiki>''
+Stages currently supports Streamable HTTP.
