Workspace agents that do the repeat work.

Last updated · By Chris Tabb, founder · Sources checked November 13, 2026

Workspace agents let a ChatGPT Business or Enterprise team build an agent once and run it on repeat: on a schedule, in Slack, or from an API call, connected to your apps and custom MCP servers. They are not OpenAI’s migration path for custom GPTs (that is plugins), but some GPTs that ran recurring or shared work fit better as an agent before custom GPTs retire on December 11, 2026. Appearly designs, connects, and governs them. We are not affiliated with OpenAI.

§ 01

What is a ChatGPT workspace agent?

OpenAI describes workspace agents as agents for repeatable tasks and workflows in ChatGPT. You can create one from a template or describe it in the builder, test it with a preview, and publish it. OpenAI’s own examples include meeting follow-ups, routing vendor and approval requests, and qualifying inbound leads.

§ 02

How workspace agents connect: apps, MCP, Slack, and APIs

ConnectionWhat it does
Apps and toolsRead and act in the services your workspace allows
Custom MCP serversConnect systems that have no ready-made app, including rebuilt custom GPT actions
Skills and filesReusable instructions and reference material
ScheduleRun the agent on a recurring schedule, with extra instructions if needed
SlackAdd the agent to a channel through the ChatGPT Agents app; a Slack admin may need to approve
API triggerStart the agent from an internal workflow, support tool, or scheduled job

§ 03

The admin controls to set before anyone builds

  • Who can run agents, who can build them, and who can publish to the workspace directory.
  • Whether anyone may publish agents that use their own app connections. OpenAI warns that others may then act through the builder’s credentials; keep it to people who understand that.
  • Which apps, including Workspace Agents in Slack, are enabled for which roles.

Our honest take

Most agent problems are permission problems. Decide who can publish with personal connections before the first agent ships, not after.

§ 04

Workspace agents and the custom GPT deadline

OpenAI’s direct successor to custom GPTs is the plugin, and workspace agents are the other option on Business and Enterprise for scheduled, shared, or triggered work. If a GPT ran a process rather than answered questions, it probably belongs here. See what changes on December 11 and how we migrate.

Workspace agents work best on top of good Company Knowledge and connectors, which is how we usually scope the two together.

§ FAQ

Questions we hear

What are ChatGPT workspace agents?

Workspace agents are agents that Business and Enterprise teams build in ChatGPT for repeatable tasks. They can use apps, tools, custom MCP servers, skills, and files, and run on a schedule, in Slack, or from an API trigger.

Can workspace agents use MCP?

Yes. OpenAI says you can add custom MCPs, along with tools, apps, skills, and files, in the agent builder.

Are workspace agents available on ChatGPT Business?

Yes. OpenAI documents workspace agents for Business and Enterprise. In Enterprise workspaces they are off by default at launch and admins enable them.

Do workspace agents replace custom GPTs?

Not directly. OpenAI’s migration path for custom GPTs is a plugin (My GPTs → Migrate to plugin), with a Project as an alternative for personal work. Workspace agents are a separate product for scheduled, shared, or trigger-based workflows. Custom GPTs retire on December 11, 2026.

What does Appearly charge to set up agents and connectors?

Company Knowledge setup, which covers connectors and putting workspace agents to work, starts at $2,500. Custom GPT migration starts at $2,500 as a fixed fee. Appearly is not affiliated with OpenAI.
