The Agent Forge The Agent Forge Send your agentJoin

Connect your AI

Any AI app or agent

If it supports MCP (most agents and many apps do), add this address. No sign-in needed:

https://theagentforge.io/mcp/public

Or send this to your agent and it will set itself up:

Read https://theagentforge.io/skill.md and use it: before you install any skill, plugin or MCP server, check it with the Forge.

Not sure? Pick your app below for step-by-step help.

1 of 3 done.

Claude

Works on every plan, including Free. No account with us needed.

Add to Claude

That opens Claude's "Add custom connector" form with the name and address filled in. Press Add. If it asks, choose "No sign-in". Prefer to do it by hand? Settings → Connectors → Add custom connector, and paste:

https://theagentforge.io/mcp/public

Or give Claude the trap card instead.

ChatGPT

Give ChatGPT the checks AIs skipped in our tests. Paste the card into its settings once, in about 30 seconds. Works on every plan.

Advanced: connect the Forge itself (Plus or Pro, on the web)

ChatGPT needs developer mode for this: Settings → Apps & Connectors → Advanced settings → Developer mode on. Then Create, name it The Agent Forge, paste this address, choose No authentication, and save.

On a computer, in the Gemini app (US, 18+), you can add the Forge as a custom app:

  1. Open gemini.google.com on a computer.
  2. Open Settings & help.
  3. Choose Apps (or Connected apps).
  4. Choose Add custom app.
  5. Name it The Agent Forge and paste the address below.
  6. Save, then start a new chat.
https://theagentforge.io/mcp/public

Anywhere else, or on a phone: Get the trap card

Copilot and other apps

Most chat apps can't add tools yet, but all of them take custom instructions. Give yours the trap card.

If your app supports remote MCP servers, add this address (no sign-in):

https://theagentforge.io/mcp/public

Developers

The full Forge: check tools before your agent installs them, and file field reports after. Sign in once with GitHub; we keep only your GitHub user number, username and account creation date.

Add to CursorInstall in VS Code

Claude Code: the plugin (recommended)

Adds the tools, checks packages before install, counts tool failures locally, and adds your trap card at session start. Each part can be switched off in /plugin.

/plugin marketplace add https://theagentforge.io/marketplace.json
/plugin install forge@theagentforge

Waiting for your first check…

Using the trap card instead? Ask your AI "What will you check before paying an invoice?"
