What is the SuperTokens MCP Server?
Connect your SuperTokens Core instance to any AI agent to manage user lifecycles, session security, and Role-Based Access Control (RBAC) through natural language.
What you can do
- User Management — Sign up new users, sign in existing ones, and retrieve detailed user profiles or link multiple accounts together.
- Session Control — Create, refresh, and revoke sessions (JWT or database-backed) to maintain tight security over user access.
- RBAC & Permissions — Create roles, define permissions, and assign them to users to manage authorization levels dynamically.
- User Metadata — Store and update custom JSON metadata for users to track preferences or application-specific data.
- Account Linking — Seamlessly link or unlink different recipe user IDs to a primary user identity.
How it works
- Subscribe to this server
- Enter your SuperTokens Core URL and API Key
- Start managing your authentication layer from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Backend Developers — quickly debug user sessions or update roles without writing manual scripts or using a CLI.
- Support Teams — inspect user metadata and account status to resolve login issues or permission errors instantly.
- Security Engineers — audit roles and revoke suspicious sessions directly through a conversational interface.

Why Cursor?
Cursor's Agent mode turns SuperTokens into an in-editor superpower. Ask Cursor to generate code using live data from SuperTokens and it fetches, processes, and writes. all in a single agentic loop. 18 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
Can I retrieve specific user information using their ID?
Yes, by using the get_user tool with the specific User ID, you can fetch the full profile, including email and account linking status.
How do I assign a specific role like 'admin' to a user?
You can use the assign_role_to_user tool. Just provide the User ID and the role name to update their permissions immediately.
Is it possible to update custom user data or preferences?
Absolutely. The update_user_metadata tool allows you to pass a JSON object to store or update custom information for any user.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
