About 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.
LangChain's ecosystem of 500+ components combines seamlessly with SuperTokens through native MCP adapters. Connect 18 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
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.
The SuperTokens MCP Server exposes 18 tools through the Vinkius. Connect it to LangChain in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
