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, andsignin_passwordless_email. - User Management — Register new accounts with
signup_email_password, retrieve profiles withget_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_tokenandsignout. - Cloud Storage — Upload files directly to your Nhost buckets using the
upload_filetool, supporting both text and base64 content.
How it works
- Subscribe to this server
- Provide your Nhost Auth and Storage URLs from your project dashboard
- Start managing users and files from Claude, Cursor, or any MCP client
Who is this for?
- Full-stack Developers — manage user sessions and test auth flows directly from the IDE without switching to the browser.

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 Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
