The Agent Forge app running a workflow called Ship a feature: a plan writer, a developer, a PR reviewer and a release captain take turns, then the release notes arrive in the run log.

Skills, tools and any model. Built on open standards.

Skills

Questions, answered.

Is Agent Forge free?

Yes. The app is free to download. Model calls are billed by your AI provider through the Vercel AI Gateway token you add in Settings.

What is an agent in Agent Forge?

An agent is a folder in ~/AgentForge/agents. It holds agent.json (name, model, settings), SYSTEM.md (the system prompt), a skills folder and an mcp folder. You can open, edit, version and share it like any other folder.

Which AI models can my agents use?

Any chat model available on the Vercel AI Gateway, such as Claude, GPT or Gemini. Set a default in Settings and override it per agent.

Where do my agents and conversations live?

On your computer, as files under ~/AgentForge. Model requests go to the model you picked through the Vercel AI Gateway. MCP sign-in tokens are stored on your computer, outside the shareable agent folder.

Do I need to write code?

No. You create agents, install skills, add MCP servers and wire workflows in the app. Everything it saves is plain text, so you can also edit it by hand.

Can I use my existing skills and MCP servers?

Yes. Skills use the open Agent Skills format (a folder with a SKILL.md), and MCP servers are standard stdio or hosted servers. Install from skills.sh and the MCP Registry, or drop your own files into the agent folder.

What happens to the photos for my avatar?

They go once from your computer to the image model you chose, through your own gateway key, and are deleted as soon as the character is drawn. Agent Forge has no servers of its own, so nothing is uploaded anywhere else.

Does it run on Windows or Linux?

Agent Forge runs on macOS and Windows. Linux is not supported yet.
