How to Use the Nhost MCP in CrewAI

Q: Can a CrewAI agent reset a user password on Nhost?

Yes, your support agent can call resetpassword when a user requests help. The agent initiates the password reset flow, and the backend handles sending the recovery email directly to the user.

Q: Can I limit which CrewAI agents have access to sensitive auth tools?

Yes, you can use CrewAI's tool filtering to expose getuser only to your admin agent, while restricting your research agents to basic storage tools like getfile.

Q: How secure are the Nhost files processed by CrewAI agents through this MCP server?

Highly secure. File data retrieved via getfile is processed in memory and never written to disk. The server uses ephemeral V8 sandboxes to ensure that no file content or user details persist after the task ends.

Multi-agent user management in CrewAI

The `signup_email_password` tool allows your registration agent to provision new accounts while a separate auditor agent verifies the profile details. They coordinate through shared memory to ensure only valid users get created. If a profile needs verification, the moderator agent calls `signin_otp_email` to send a one-time passcode. Once the user provides the code, the crew updates the account status autonomously.

Multi-agent file moderation via MCP Server

The `get_file` tool retrieves uploaded assets so your analyzer agent can inspect them for policy compliance. If the file violates rules, the moderator agent immediately executes `delete_file` to remove it from your bucket. For approved assets, the storage agent runs `get_file_presigned_url` to generate temporary download links. These links are then automatically shared with the rest of the crew for downstream processing.

Shared session persistence

The `refresh_token` tool ensures all agents in your crew share a valid authentication state when interacting with protected endpoints. When one agent updates the token, the new JWT is shared across the crew's common memory. When the operational cycle finishes, the coordinator agent executes `signout` to terminate the shared session. This prevents stale credentials from remaining active in your environment.

Setup guide

Set up Nhost MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke Nhost tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="Nhost Analyst",
    goal="Access and analyze Nhost data via MCP.",
    backstory="Expert analyst with direct Nhost access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent Nhost transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="Nhost Analyst",
        goal="Access and analyze Nhost data via MCP.",
        backstory="Expert analyst with direct Nhost access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Nhost transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()
    print(result)

Common questions about Nhost MCP in CrewAI

One agent can generate the file metadata and pass it to a storage agent that calls `upload_file`. The resulting metadata is saved in the crew's shared memory, allowing other agents to access the file immediately.

Yes, your support agent can call `reset_password` when a user requests help. The agent initiates the password reset flow, and the backend handles sending the recovery email directly to the user.

The crew's coordinator agent monitors the session and calls `refresh_token` whenever the JWT nears expiration. This keeps the database connection active for all agents working on the task.

Yes, you can use CrewAI's tool filtering to expose `get_user` only to your admin agent, while restricting your research agents to basic storage tools like `get_file`.

Highly secure. File data retrieved via `get_file` is processed in memory and never written to disk. The server uses ephemeral V8 sandboxes to ensure that no file content or user details persist after the task ends.
