Cowork does the work.
Let it publish the result.
A long task ends with a folder of files, which is one step short of useful. With agenthost connected, it ends with an address you can send to someone instead.
The output of an hour’s work should not be a zip file.
Cowork is at its best on the jobs that take a while: go through this, build that, tidy all of it up. What you get back is real work, and then it sits in a folder waiting for someone to do something with it. Sending a zip around is how good work quietly stops mattering.
agenthost gives Cowork somewhere to put it. It is a connector, so publishing becomes part of the task rather than a thing you do afterwards. You can ask for it up front: build the dashboard, then put it online and send me the link. Cowork does both, and the last thing it says is the address.
Because it is the same connector across Claude, adding it once covers Cowork, the apps and claude.ai together. And because there is nothing to configure on our side, a long unattended task never stalls waiting for you to answer a question about build commands.
You ask for it in a sentence.
There are no commands to learn on our side. These are whole sentences, typed the way you would say them to a person, and each one is a thing agenthost does.
put the finished site online when you're done
Publishing becomes the last step of the task rather than a separate errand. You come back to a link, not a folder.
only the four people on the project should see it
Locks it to the addresses you name. Everyone else gets a closed door, and it stays out of search results.
give each of those reports its own page
Several separate things online at once, each with its own address, in one project.
the numbers changed, republish it
Replaces the live version at the same address, so the link you already sent still works.
take the old one down
Removes it properly. What you stopped using stops costing anything.
There is more of this in the how-to guides, which are written for your agent to read as much as for you.
Whatever it built, it can publish.
You do not have to know what it is made of. Your agent works that out and tells us.
A website or page
The one-pager, the portfolio, the event invite. Files, served fast, with nothing to build first.
Ten free, forever, no card.
How it works →An app that saves things
Sign-ups, notes, bookings, orders. Somewhere to run and a database to remember, together.
€4 a month, database included.
How it works →Node, Python, PHP
Express, Flask, Django, a script that has to run. One fixed convention each, and no build command to get right.
The contract, in full.
What runs here →- framework preset
- build command
- output directory
- install command
- API keys
- credit card
- region
Nothing here can stop and ask you a question.
Every one of these is a setting some other host would demand before it would take your files. None of them exists here, which is why your agent can go from a folder to a working link without checking in.
- Dockerfiles
- port settings
- TLS certificates
- DNS records
- CI pipelines
- health checks
- scaling rules
The one thing agenthost does expect is an entrypoint per runtime, and the deploy reference is where Claude Cowork reads it before the first deploy.
How it connects.
Cowork uses the connectors on your Claude account, so this is added once in Claude’s settings and is then available in Cowork.
By hand: Settings → Connectors → Add custom connector, and paste https://agenthost.eu/mcp.
Add the connector
The button opens the add-connector dialog with agenthost's name and address already filled in. You review it and approve.
Sign in with your email
Claude sends you to agenthost, you type the code we email you, and you approve the connection. That step also makes your account if you are new.
Turn it on for the task
agenthost now appears among your connectors in Cowork. Ask for the work and for the link in the same breath.
On a Team or Enterprise plan an owner adds the connector once for the organization, and everyone else just signs in. The get started page walks through all of it, with the buttons and the sign-in step.
The usual ones.
Do I have to add it separately for Cowork?
No. Custom connectors belong to your Claude account and are available across the Claude apps, claude.ai and Cowork. Add agenthost once and it is there.
Does it work with a self-hosted server on our network?
That is worth knowing about connectors generally: Claude reaches a remote connector from Anthropic's own infrastructure rather than from your laptop, so anything behind a VPN or a company firewall will not connect. agenthost is on the public internet, so it does.
What if Cowork is running while I am away?
That is the case this is built for. There is no build command to declare and no framework to pick, so there is nothing for the task to stop and ask you about. It deploys, checks the app answered, and tells you where it went.
Can it publish something private to just a few people?
Yes. Name the email addresses allowed in and only those people can open it, or put a single password on the door and pass it on. Either way it stays out of search engines.
Is there an API key to paste anywhere?
No. agenthost signs you in through your browser, and your agent never sees a password or a key. There is nothing to copy out of one window and into another, and nothing to rotate later.
What does it cost to try?
Nothing, and there is no card. Your first ten websites are free and stay free. You only pay when the thing you built has to run code on our side, or when you want it on your own domain.
Can I connect more than one agent to the same account?
Yes, as many as you like. They all see the same projects, so you can build something in one and update it from another. Connecting the second one is a single click, because your browser is already signed in.
Where is this actually hosted?
In the EU, by a European company. Your files, your database and your logs stay here, and so does the billing.
Not what you use?
agenthost is a standard remote MCP server, so anything that speaks MCP can drive it. These are the ones with a page of their own.
