Pega Infinity Authoring plugins

Pega Infinity Authoring plugins connect development environments to Pega MCP, enabling you to build Pega applications from a development environment of your choice. By making internal assets available to external tools and agents, Pega is evolving its low-code approach to make application development more automated and accessible to users with different tool preferences.

The repository contains client-specific plugin payloads, marketplace layouts, and checked-in run-time artifacts and skills for producing installable packages.

Installing the plugin from the marketplace

Use this repository as the source when you install a marketplace from a Git path. The following table lists marketplace plugins and commands:

Agent	CLI command
Claude Code	claude plugin marketplace add https://github.com/pegasystems/infinity-ai-plugins.git claude plugin install pega-infinity-authoring@Pega
GitHub Copilot CLI	copilot plugin marketplace add https://github.com/pegasystems/infinity-ai-plugins.git copilot plugin install pega-infinity-authoring@Pega * Restart Copilot CLI for the plugin changes to take effect
Codex	codex plugin marketplace add https://github.com/pegasystems/infinity-ai-plugins.git codex plugin add pega-infinity-authoring@Pega Alternatively, launch codex, type /plugins, navigate to Pega, and install Pega Infinity Authoring

Alternatively, you can use SSH Git URLs such as git@github.com:pegasystems/infinity-ai-plugins.git.

Setting up the plugin manually

Clone the repository, and then configure the MCP server and skills manually. The following table lists setup instructions for clients without a marketplace plugin:

Agent	Setup instructions
Devin	Configure the bundled MCP server in Devin's MCP metadata and copy the shared Pega skills into a Devin skill directory. See Devin setup instructions.
opencode	Merge the mcp block from plugins/pega/infinity-ai-plugins/opencode/opencode.json into opencode.json. Set cwd to the absolute path of the sibling claude/ directory. Copy plugins/pega/infinity-ai-plugins/opencode/skills/ into .opencode/skills/ in your project. See opencode setup instructions.

Setting up the plugin after installation

Claude Code, GitHub Copilot CLI, and Codex plugins include a built-in pega-setup skill for first-time configuration and troubleshooting.

Devin and opencode users can install the same shared skills by following the Devin setup instructions and opencode setup instructions.

After installing a marketplace plugin or completing manual setup, start a new session and ask the assistant to run pega-setup.

The pega-setup skill:

• Checks whether the plugin run time is available and whether the client can connect to Pega Infinity
• Guides the user through setting up the Pega Infinity base URL, optional OAuth client ID, and write access
• Verifies the connection after configuration

When setting pega_base_url, use the environment root URL only. Do not include /prweb or any other path segment.

Updating marketplace installations

When this repository publishes a new plugin build, refresh the installed plugin from the marketplace. The following table lists the update commands:

Agent	Update steps
Claude Code	Run claude plugin marketplace update Pega to refresh the marketplace catalog. Then run claude plugin update pega-infinity-authoring@Pega to update the installed plugin. Run /reload-plugins or start a new Claude session afterward.
GitHub Copilot CLI	Run copilot plugin marketplace update Pega to refresh the marketplace catalog. Then run copilot plugin update pega-infinity-authoring@Pega to update the installed plugin. Quit and reopen Copilot CLI afterward.
Codex	Run codex plugin marketplace upgrade Pega to refresh the marketplace catalog. Then run codex plugin add pega-infinity-authoring@Pega to refresh the installed plugin, or use the /plugins browser to reinstall it from Pega. Start a new Codex session afterward.

Updating manual installations

To update a manual installation, follow these steps:

Agent	Update steps
Devin	Run git pull in the cloned repository, then start a new Devin session. Recopy the shared Pega skills if they changed. See Devin setup instructions.
opencode	Run git pull in the cloned repository to get the latest files. Restart opencode afterward.

Tip

If adding the marketplace or cloning this repository fails with a "Filename too long" error, enable Git long-path support:

git config --system core.longpaths true

Overriding local skills

To test local infinity-skills with Claude Code, GitHub Copilot CLI, or Codex, set the pega_skills_path entry to the parent directory that contains the version directories. Set the entry in ~/.infinity-rules-mcp/config.json or %USERPROFILE%\.infinity-rules-mcp\config.json before you start the client.

{
  "pega_base_url": "https://example.pega.example.com",
  "pega_skills_path": "/path/to/infinity-skills"
}

Point pega_skills_path at the parent directory that contains the selected version directory, and set pega_infinity_version to the matching directory name.

If pega_skills_path is missing or empty, the plugin uses the bundled or cached skills payload.
