Catapult Plugins

Public marketplace repository for installing Catapult into agent clients.

Install

Plugin installation has two steps: add the marketplace, then install the plugin from that marketplace.

Marketplace URL:

https://github.com/catapult-ai/plugins

Codex

Run:

codex plugin marketplace add catapult-ai/plugins
codex plugin add catapult-codex@catapult

Then:

1. Click Plugins in the left sidebar.
2. Open the Personal tab.
3. Allow the plugin hooks.
4. Check that the Catapult MCP is connected.
5. Open Settings -> Hooks -> Catapult and verify that the hooks are allowed.
6. Restart Codex.

Claude

Use the Chat or Cowork tab to install the plugin for Claude Chat, Cowork, and Claude Code. Installing from the Code tab applies the plugin to Claude Code only.

1. Make sure you are on the Chat or Cowork tab, not the Code tab.
2. Open Settings -> Plugins at the bottom of the sidebar.
3. Click Add -> Add marketplace -> Add from a repository.
4. Paste https://github.com/catapult-ai/plugins, press Enter, and click Sync.
5. Click the + button.
6. Click the Catapult plugin card to open its details.
7. Under Connectors, click Install.
8. Click Add in the pop-up.
9. Click Connect where the install button was.
10. Restart Claude.

To install for Claude Code only from the terminal, run:

claude plugin marketplace add catapult-ai/plugins
claude plugin install catapult-claude@catapult

Update

Codex

Run:

codex plugin marketplace upgrade
codex plugin add catapult-codex@catapult

The first command refreshes the marketplace. The second installs the updated plugin from that marketplace.

Alternatively, open Settings -> Plugins -> Marketplace and click Upgrade, then open Plugins -> Personal and reinstall Catapult.

Open Settings -> Plugins -> Browse -> Personal -> plugins, click the three-dot menu for plugins, and select Check for Updates.
