Level up

Your AI can do more than hand you a PDF.

AgentSpace gives any AI (ChatGPT, Claude, GLM and others) a place on the web. It keeps files, runs code and publishes sites and interactive dashboards at an address with your name.

Get my free space See how it works

Free: 100 MB and 1 site, no card. Plans from R$ 4.90 a month.

Instead of a file, the finished thing, online

Ask your AI for what you already ask for, and get a link instead of an attachment.

~~A spreadsheet~~ → An interactive dashboard

Take this sales data [paste or attach it] and build an interactive dashboard with charts and filters. Publish it to my AgentSpace and send me the link.

~~A PDF~~ → A site that reads well on a phone

Turn this report [paste or attach it] into a one-page site that looks good and reads well on a phone. Publish it to my AgentSpace.

~~Loose photos~~ → A carousel site

Make a carousel site with my product photos [attach them], with a title and a price on each, and publish it to my AgentSpace.

Copy, paste, done

Create your space. It's free and takes less than a minute.
Copy the text you're shown and paste it into your AI. Your key is already in it.
Ask for whatever you want. The AI connects by itself, builds it and sends you the link.

In an AI that has tools

Claude Code, Codex, Cursor, GLM, Gemini CLI and any agent that can reach the internet.

This is what you paste (after signing up, your key replaces this example one):

You're going to work in my AgentSpace: a space on the internet where you can keep files, run code and publish pages at a public address.

- Manual (read it first): https://agentspace.com.br/llms.txt
- My key: ask_EXAMPLE_your-key-goes-here
  (send it as the header "Authorization: Bearer ask_EXAMPLE_your-key-goes-here")
- MCP server: https://agentspace.com.br/mcp
- REST API: https://agentspace.com.br/api/v1
- My username: @you

Connect whichever way you can. If you can install the MCP server permanently, do; otherwise use the REST API. Confirm by calling whoami.

First task: make an interactive dashboard of this month's sales (make up the data) and publish it. Send me the link.

In ChatGPT or Claude

In the browser or the app. No key needed here:

In the app's settings, find Connectors.
Add a custom connector with the address https://agentspace.com.br/mcp
Approve the access on the AgentSpace page that opens.

Then just ask: “publish this to my AgentSpace”.

An address with your name

https://agentspace.com.br/@you/ your address
https://you.agentspace.com.br/ your own subdomain
https://your-domain.com/ coming soon

For developers

One key opens three doors onto the same space. Every response carries a guide with the next step and every error a fix, so the agent finds its own way. Details in the agent manual and the API reference.

REST

For any agent that can make an HTTP call.

curl https://agentspace.com.br/api/v1/whoami \
  -H "Authorization: Bearer ask_..."

MCP

Streamable HTTP. Put the address in your client and the tools appear.

claude mcp add --transport http agentspace \
  https://agentspace.com.br/mcp \
  --header "Authorization: Bearer ask_..."

A2A

A public agent card, so other agents can discover it and delegate.

GET https://agentspace.com.br/.well-known/agent-card.json

Your AI already knows how to make things. Give it a place to publish them.
