What is the Nhost MCP Server?

Connect your Nhost project to any AI agent to manage your backend services through natural language. This server provides a comprehensive interface for Nhost's Authentication and Storage services.

What you can do

Authentication Flows — Sign in users via email/password, OTP, magic links, or anonymous sessions using signin_email_password, signin_otp_email, and signin_passwordless_email.
User Management — Register new accounts with signup_email_password, retrieve profiles with get_user, and handle password resets or email changes.
Session Control — Refresh access tokens and securely sign out users from single or all devices using refresh_token and signout.
Cloud Storage — Upload files directly to your Nhost buckets using the upload_file tool, supporting both text and base64 content.

FAQ

Frequently asked questions

How can I retrieve the profile of the currently logged-in user?

Use the get_user tool. It fetches the authenticated user's profile information, including their ID and metadata, provided a valid JWT is configured.

Is it possible to store documents or images using this server?

Yes. The upload_file action allows you to send raw text or base64 content along with a filename directly to your Nhost Storage bucket.

Can I initiate a login without requiring a password?

Absolutely. Use the signin_passwordless_email tool to send a magic link to a user's email address for a seamless passwordless authentication experience.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
