Connect your agent
Add agenthost to Claude, Claude Code, Cursor, VS Code or any MCP client, sign in with your email, and you're done. No API key, no password in a chat window.
You do this once. After it, putting something online is a sentence.
agenthost is a standard remote MCP server at https://agenthost.eu/mcp. Any client that speaks MCP
can use it, and the sign-in happens in your browser rather than in the chat.
Add it to your client
Works in the Claude app and on claude.ai.
- Open Settings → Connectors → Add custom connector.
- Name it
agenthostand paste the addresshttps://agenthost.eu/mcp. - Approve it. Claude sends you to agenthost to sign in.
The get started page has a button that opens that dialog with both fields already filled in.
Sign in
The first time your client calls agenthost, it opens a page in your browser.
Enter your email address
We email you a six-digit code. It works once and expires after about ten minutes.
Type the code back
If the address is new to us, this same step creates your account: you name your organization and accept the terms. There is nothing else to fill in.
Approve the client by name
You see which client is asking — "Claude", "Cursor" — and approve it. Only then does it get a token.
That's it. Your browser stays signed in for 30 days, so connecting a second client later is a single click.
Nothing is ever pasted into a chat window
No password, no API key, no token. Your agent never sees your credentials, and you never have to handle one. If you belong to more than one organization, the sign-in page asks which one this connection is for.
Check that it worked
Ask your agent:
who am I on agenthost?
It calls whoami and tells you the account, the organization and your role.
If that answers, you are connected and can deploy something.
If something goes wrong
| What you see | What it means | What to do |
|---|---|---|
| The agent says it isn't authenticated | The connection expired or was revoked | Reconnect the agenthost server in your client and sign in again |
| No email arrived | Wrong address, or it's in spam | Check the address, look in spam, then try again — codes are rate limited per address, so wait a few minutes if you've tried several times |
| "Invalid code" | The code expired or was used | Request a new one; codes last about ten minutes and work once |
| Your agent can't see any agenthost tools | The server isn't connected in that client | Re-check the address, and that the server is enabled for the current project or workspace |
For agents that can't open a browser
CI, a cron job, a script — anything unattended — uses a long-lived API token instead. Sign in once as a human, ask for a token, and send it as a bearer header. See Deploy from CI or an unattended agent.
What agenthost is
Hosting your agent drives. You ask for a link; your agent sends the files and we run them. What you need, what you can put online, and what you never have to learn.
Your first deploy
From a connected agent to a live link — what to say, what happens, what you get back, and how to know it actually worked.
