Stack0 Agents

Stack0 Agents gives your workspace AI agents that do work for you. Each agent has its own email address, a browser on a private cloud machine, and access to the services you connect. You talk to it in chat, and it asks you before it starts work that needs approval. It is a hosted app at agents.stack0.dev.

Open Agents

Go to agents.stack0.dev/dashboard and sign in with your Stack0 account. Each organization has its own URL, /dashboard/orgs/<org>. Everyone in the organization shares the same agents and can see their work.

Hire an agent

  1. Click Get started on an empty workspace, or Hire an agent in the sidebar.
  2. Describe the job in one sentence, for example "Chase every sales thread that goes quiet and log it in the CRM." You can leave it empty, and the agent asks you what to do.
  3. Click Hire them.

Stack0 writes the agent's name, role, personality, and instructions from your sentence. It then sets up the agent's machine and email inbox and opens the chat. The organization needs an active Stack0 plan. The plan sets how many agents the workspace can have.

Give an agent work

Select the agent in the sidebar and type in the Message box. The panel next to the chat has five tabs.

  • Screen

    The page the agent's browser has open now. It refreshes every 5 seconds while the tab is open.

  • Work

    The agent's tasks, grouped as Needs you, In progress, Scheduled, and Done. Click Approve or Reject on a task under Needs you.

  • Inbox

    The agent's email address and the mail it received. Mail from a member of the workspace goes to the agent. Mail from an unknown sender is held and does not reach the agent.

  • Knows

    The documents the agent wrote, and the documents shared with every agent.

  • Activity

    A log of what the agent did.

Each morning, agents write a brief. Each Friday afternoon, each agent reviews its week and adds what it learned to its instructions. Both use the workspace timezone.

Connect services

On the Connections page, an owner or admin connects the services an agent uses for you.

  • Google

    Gmail, Drive, Sheets, and Calendar. Click Connect and approve access in Google.

  • Stripe

    Read revenue, customers, and subscriptions. Click Add key and paste a restricted key with read access.

For a site with no API, add the site's login on the Saved logins page. Logins are encrypted. The agent types them into the site in its own browser. You cannot read a saved login back from the dashboard.

Agent settings

The Agent page has these settings. Only owners and admins can change them.

  • Identity

    Name, role, and personality. A personality change applies after the next redeploy.

  • Model

    The chat model: Claude Opus 4.8, Claude Sonnet 4.6, Claude Haiku 4.5, GPT-5.4, GPT-5.4 mini, or Grok 4.1 fast. A change applies to the next message.

  • Schedule

    Turn on Work on its own to have the agent wake up and pick up approved tasks every 15 minutes, 30 minutes, hour, 4 hours, or once a day.

  • Deployment

    The machine's status. Redeploy sends the current instructions and knowledge to the machine.

Workspace settings

  • Settings

    The workspace name, the timezone for the morning brief and weekly review, and your website, which agents read to learn what you do. An owner can delete the workspace here.

  • Members

    The people in the workspace. Invite someone by email.

Billing

Agents is part of the Stack0 Platform plan, $20 a month, with every other Stack0 product. The plan includes $10 of usage credit each period, shared across all products. AI calls an agent makes on Stack0's keys are billed at cost plus 50% and use that credit first.

The Billing page shows the plan, the credit left, and what agents spent this period. It also shows how many agents the plan allows and how many agent runs can go at once. Extra runs wait in a queue. The Usage page shows spend, calls, and tokens for the last 30 days, by service and by day. You subscribe and pay on Stack0 Cloud at cloud.stack0.dev/dashboard/orgs/<org>/billing. See pricing.

Connect a coding agent

Stack0 Agents is separate from coding agents such as Claude Code. To connect Claude Code or another MCP client to Stack0, use the MCP server at https://cloud.stack0.dev/mcp. Set it up from the organization's Agents page on Stack0 Cloud, at cloud.stack0.dev/dashboard/orgs/<org>/settings/agents. For Claude Code:

bash
claude mcp add --transport http stack0 https://cloud.stack0.dev/mcp

Stack0 Agents does not serve MCP tools yet.
