How to install and use the WorkOS plugin in Claude, ChatGPT, and Codex

WorkOS’s MCP plugin connects Claude, Claude Code, ChatGPT, and Codex to the WorkOS MCP server through OAuth, allowing agents to manage WorkOS resources such as SSO and Directory Sync connections, organizations, invitations, authentication policies, audit logs, and AuthKit branding within the user’s existing dashboard permissions. Each platform uses the same server URL but has different installation and reauthentication methods, ranging from marketplace connectors to CLI commands and project-level configuration. Access is additionally governed by team settings for MCP enablement, production access, and write permissions, while agents are scoped to a selected WorkOS team and typically default to sandbox environments. The server uses a limited discover-then-execute tool model, enabling users to investigate issues, review configurations, create test organizations, invite users, and perform other tasks through natural-language requests without navigating multiple dashboard pages. Security safeguards prevent access to sensitive credentials, restrict certain administrative actions, log all agent activity under the authenticated user, and require explicit confirmation before irreversible deletions.
