Description

From the marketplace listing

Connect your Otter account to manage website A/B tests and understand experiment results. Find projects, check installation instructions, inspect pages for visual changes, create redirect or visual experiment drafts, manage experiment status, and read results. Results use Otter's server-side statistical interpretation, including Bayesian and frequentist analysis. You choose which Otter account to connect and approve its permissions; access remains limited by your current role. An active Otter account is required. Website changes require the Otter SDK to be installed. Creating a draft does not launch it. You can revoke the connection from Otter's Connected apps page.

Declared limitations

  • Page inspection requires a verified SDK installation. The example.com project is intentionally unverified.
  • Project 56 is a separate sample account fixture, inaccessible to the reviewer membership. It contains no customer data.
  • The review pricing draft has no experiment visitors or conversions. A request cannot invent evidence or authorize a winner.

Release notes

Version 1.0.4 fixes the connection permissions found in review. Each tool now declares the OAuth scope it needs, so ChatGPT requests project, experiment and results access when linking instead of identity scopes alone. A call missing a scope returns an insufficient_scope challenge that lets ChatGPT reauthorize. create_experiment_draft and update_experiment_draft are renamed create_experiment and update_experiment, because both can start or resume an experiment, and update_experiment is annotated open-world. Review cases that act on a named draft now name the most recent one, so they pass when rerun on web and mobile. No embedded custom UI. All sample experiments remain drafts.

Declared in the saved package. Remote tools may change independently.
