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.

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.
DevOps Engineers — automate user provisioning and file management tasks through simple conversation.
Support Teams — quickly verify user profile information and account status to resolve customer issues faster.

Why CrewAI?

When paired with CrewAI, Nhost becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Nhost tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

—
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
—
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the mcps parameter and agents auto-discover every available tool at runtime
—
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
—
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

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 CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
