:write scope includes its :read scope. The exception is files:write, which lets an app upload files without reading the user’s other files.
Scopes available today
New scopes in this proposal
Document actions such as Translate need
files:write, because they create files, and files:read for their inputs.
Defaults
An app that requests no scope gets every scope exceptdirectory:admin. directory:admin only narrows what the person who approves it can already do: an organisation admin’s token can administer the organisation, a team admin’s only their own teams. On the MCP server, one tool uses it, manage_organisation, and a host has it only when it asks for it. Apps connected before a new scope existed are asked to approve it the next time the user reconnects. Until then the new endpoints and MCP tools return 403 insufficient_scope, naming the missing scope.
Scopes and MCP tools
The MCP server lists only the tools a token can use. A connection granted onlyresearch:read sees two tools, legal_research and get_operation, not twenty-six. See MCP tools for each tool’s scope.
