How to Use the Nhost MCP in Claude Code

Q: How do I register the Nhost MCP server in Claude Code?

Run claude mcp add --transport http nhost -- in your terminal. This adds the server to your /.claude.json configuration file so the CLI can access the fifteen tools.

Q: Can I use Claude Code to automate Nhost file uploads?

Yes, Claude Code calls uploadfile to send local assets to your bucket. You can run this command directly or integrate it into your terminal-based build scripts.

Q: How does Claude Code handle Nhost authentication?

Claude Code uses signinemailpassword to log in and retrieve a JWT. It stores this session token locally to authenticate subsequent tool calls.

Q: Can I test passwordless login flows from the CLI?

Yes, you can use signinpasswordlessemail to send a magic link. The agent triggers the email delivery and outputs the status directly to your terminal.

Run headless auth tests and manage storage buckets from your terminal using this Nhost MCP Server.

Perplexity

Headless user management via Claude Code

The `signup_email_password` tool registers new accounts directly from your terminal session. Claude Code can use this to quickly seed test users during CI/CD runs or local shell scripts. This eliminates the need to write custom curl commands or seed scripts. You can also initiate one-time password flows with `signup_otp_email`. This lets you verify that your transactional email services are sending OTPs correctly without opening a browser.

Scripted file transfers and asset cleanup

The `upload_file` tool pushes raw files from your local directory to your remote storage bucket. Claude Code uses this to automate asset uploads during build pipelines or deployment scripts. To manage access, `get_file_presigned_url` generates temporary download links. You can pipe these links directly to other CLI utilities or use them to test secure downloads in your terminal.

Command-line session validation

The `refresh_token` tool exchanges an expired token for a active JWT to maintain your terminal session. Claude Code runs this automatically to keep your API scripts authenticated during long-running tasks. When testing session expiration, `signout` invalidates the active tokens immediately. This lets you confirm that your API gateways reject expired requests exactly as expected.
