About 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.

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.

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.

The Nhost MCP Server exposes 15 tools through the Vinkius. Connect it to CrewAI in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

All 15 Nhost tools available for CrewAI

When CrewAI connects to Nhost through Vinkius, your AI agent gets direct access to every tool listed below — spanning authentication, backend-as-a-service, cloud-storage, and more.

Why Use CrewAI with the Nhost MCP Server

CrewAI Multi-Agent Orchestration Framework provides unique advantages when paired with Nhost through the Model Context Protocol.

01

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

02

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

03

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

04

Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Nhost + CrewAI Use Cases

Practical scenarios where CrewAI combined with the Nhost MCP Server delivers measurable value.

01

Automated multi-step research: a reconnaissance agent queries Nhost for raw data, then a second analyst agent cross-references findings and flags anomalies. all without human handoff

02

Scheduled intelligence reports: set up a crew that periodically queries Nhost, analyzes trends over time, and generates executive briefings in markdown or PDF format

03

Multi-source enrichment pipelines: chain Nhost tools with other MCP servers in the same crew, letting agents correlate data across multiple providers in a single workflow

04

Compliance and audit automation: a compliance agent queries Nhost against predefined policy rules, generates deviation reports, and routes findings to the appropriate team

Example Prompts for Nhost in CrewAI

Ready-to-use prompts you can give your CrewAI agent to start working with Nhost immediately.

01

"Sign in user dev@example.com with password 'securePass123'."

02

"Show me the profile details for the current authenticated user."

03

"Upload a file named 'config.json' with content '{"theme": "dark"}'."

Troubleshooting Nhost MCP Server with CrewAI

Common issues when connecting Nhost to CrewAI through Vinkius, and how to resolve them.

01

MCP tools not discovered

Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
02

Agent not using tools

Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
03

Timeout errors

CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
04

Rate limiting or 429 errors

Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.

Nhost + CrewAI FAQ

Common questions about integrating Nhost MCP Server with CrewAI.

01

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.
02

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.
03

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.
04

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.
05

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.
