Optimizely Is Live in Cogny: Experiment Results, Traffic and Test Launches for Your Agent
If you run A/B tests on your site with Optimizely Web Experimentation, your agent can now read them and act on them. Optimizely is a live MCP integration in Cogny: your projects, every experiment with its variations and traffic split, the results per metric with lift and statistical significance, and the audiences, pages and events your tests use.
Connecting takes one personal access token. No app to install and no OAuth screen.
TL;DR
- Live now, included from Cogny Solo ($9/mo).
- 12 tools: 7 reads and 5 writes.
- Results as Optimizely's Stats Engine reports them: conversion rate, visitors, lift, significance, confidence interval and the declared winner or loser per metric and variation, plus how many more visitors a test needs.
- Segment by device, browser or traffic source, or narrow results to a date range.
- Writes are ask-first: create an A/B test as a draft, start or resume it, pause it, change its traffic or variation split, rename it or change its audience.
- Nothing goes live by surprise: new tests are created as drafts, and starting one is marked as a change that needs your confirmation.
What you can do with it
| Area | Reads | Writes (ask-first) |
|---|---|---|
| Projects | Every project the token can see, with platform, status and significance threshold | — |
| Experiments | Each experiment's status, type, traffic share, variations and their split, audiences, pages and metrics; filter by status | Create an A/B test as a draft; rename it, change the hypothesis or audience |
| Results | Per metric and variation: rate, visitors, lift, significance, confidence interval, winner or loser, visitors still needed; by date range, device, browser or source | — |
| Launch & traffic | — | Start or resume a test, pause it, change how much traffic enters it and the split between variations |
| Targeting & measurement | Audiences with their conditions, pages with their URLs, events (clicks, pageviews, custom) | — |
Questions this answers in one prompt:
- "Which running experiments have a significant winner on their primary metric, and how big is the lift?"
- "How many more visitors does the checkout test need before it can call a result?"
- "Does the new pricing page variant win on mobile too, or only on desktop?"
- "Pause the hero test and move the homepage test to 50% of traffic."
And with your other connections in the same workspace, it can check a winning variant against what happened in GA4 afterwards, or line a test up with the ad campaigns that sent the traffic.
Writes ask first, and say when a test goes live
Every write waits for your approval until you choose to allow it in Settings. The ones that reach visitors say so before you approve:
- Creating a test never starts it. The variations are created empty; you design them in Optimizely's Visual Editor before anything runs.
- Starting or resuming a test puts it live on your site for the audience it targets, so it is marked as a change MCP clients confirm first.
- Traffic, audience and name changes on a running test are saved, not published, unless you ask for them to go live now.
How to connect it
- In Optimizely, open Profile → API Access and click Generate New Token.
- Name it (for example "Cogny"), click Create and copy the token.
- In Cogny, open Settings → Integrations, click Connect on Optimizely and paste it.
The token is stored encrypted. It has the role its Optimizely user has on each project, so a Viewer's token can read experiments and results but can't create, start or pause anything. Disconnect any time, or revoke the token in Optimizely.
What it doesn't do yet
It covers Web Experimentation only: Feature Experimentation flags and Personalization campaigns aren't included. Variation content can't be designed from Cogny, experiments can't be archived or deleted, and audiences, pages and events are read-only. New tests are A/B tests. The full list of tools and gaps is on the Optimizely tools page.
Connect it from your Cogny dashboard and ask which of your running tests has a winner.
