Setup on Anthropic

You need a Chronulus account. The plugin connects your assistant to the hosted Chronulus server, and you sign in with your Chronulus account the first time you use it. Requests are paid from a pre-paid wallet, so add funds at console.chronulus.com before you run your first forecast or prediction.

Add the Chronulus marketplace, then install the plugin:

/plugin marketplace add ChronulusAI/plugin-marketplace/plugin install chronulus

You can also browse and install interactively. Add the marketplace as above, then run /plugin.

When the install finishes, run /mcp to confirm that the Chronulus server is connected and to complete sign-in.

The Chronulus plugin works on Claude.ai, and your forecasts and predictions appear as interactive scorecards in the conversation. Setup has three parts: add the marketplace, enable the plugin, and connect your Chronulus account.

1. Add the marketplace

1. Go to Settings → Plugins.
2. Click Add → Add marketplace.
3. Click Add from a repository.
4. Enter ChronulusAI/plugin-marketplace
5. Turn on Sync automatically.
6. Click Sync. This installs the marketplace.

2. Enable the Chronulus plugin

1. Go to Search or Discover.
2. Enter Chronulus
3. Click Add.

3. Connect your Chronulus account

The first time you use Chronulus, you will be asked to connect and log in to your Chronulus account. From time to time the Chronulus connector may ask you to reconnect. Log in the same way each time.

Start a message with a slash command, then describe what you want:

/forecast monthly foot traffic across the Brooklyn Bridge over the next 12 months

/predict Will the FOMC hike, hold, or cut its target rate at its next meeting?

The plugin includes three skills:

• forecast produces time-series forecasts with an explanation, with no historical data required.
• predict produces calibrated probabilities for yes-or-no questions and for questions with several outcomes.
• report helps you report a problem or an idea to Chronulus. Nothing is sent until you approve it.

The plugin is open source. See the plugin marketplace on GitHub for the full details. Using ChatGPT or Codex? See Setup on OpenAI.
