Humblytics is a revenue-based analytics and A/B testing platform for marketing teams. It combines analytics, heatmaps, funnels, split testing, and Stripe revenue attribution in one lightweight cookie-free script, so you can see which campaigns and page variants actually drive revenue.

Is Humblytics GDPR compliant?

Yes, Humblytics is fully GDPR compliant. It uses cookie-free tracking with hashed IPs, so no consent banners are required for analytics. Privacy policies, data processing agreements, and EU residency requirements are all in place.

Will Humblytics slow down my website?

No. The script is about 36 KB, loads asynchronously via CDN, and never blocks page rendering, so the impact on load times and Core Web Vitals is minimal.

What platforms does Humblytics work with?

Humblytics works on any website via a single script tag, with guides for Webflow (one-click App Store install), Framer, WordPress, Shopify, Squarespace, Wix, Next.js, and more. On Shopify, storefront analytics and A/B testing work today via a theme.liquid snippet, with a dedicated app coming soon.

Can Humblytics track revenue?

Yes. Stripe and Foxy are natively supported for revenue attribution, connecting every charge back to the campaign, source, and A/B test variant that drove it. Other providers can send purchase events via a custom snippet where you control the confirmation page. Shop Pay and Shopify Payments checkout revenue is not currently supported.

How long is the free trial?

14 days with full feature access. Your card is not charged until the trial ends, and you can cancel anytime. Note that upgrading to a different plan during the trial ends the trial and triggers an immediate pro-rated charge.

Best MCP-Ready CRO & Analytics Tools for 2026

The short answer: As of July 2026, the CRO and analytics tools shipping official MCP servers are Humblytics, VWO, LaunchDarkly, PostHog, Mixpanel, Convert, and Amplitude. MCP support is no longer the differentiator it was twelve months ago. What separates them now is what the agent can do once connected, and what its verdict resolves to. Humblytics, VWO, LaunchDarkly and Mixpanel all let an agent create experiments. Humblytics is the only one that scores the result in Stripe-verified revenue rather than in clicks or events.

If you are reading this, you already have an agent installed. Claude, Codex, or an SDK-built one. It ships features, debugs production, drafts copy. Then you need to A/B test a landing page and the workflow collapses into a dashboard a human has to operate.

That gap is closing fast, and the landscape changed significantly in the first half of 2026. A year ago, almost no CRO or analytics platform shipped an MCP server. Today most of the serious ones do.

This post previously claimed Humblytics was the only CRO platform with native MCP support. That is no longer accurate, and we have corrected it. VWO, LaunchDarkly, and PostHog all ship official MCP servers. The interesting question moved on, and this guide moved with it.

What MCP-ready actually means

Model Context Protocol is the open standard, originally specified by Anthropic, that lets an agent discover and operate external tools through a shared interface. An MCP-ready tool ships a server that:

Exposes its capabilities as discoverable tools
Accepts structured calls with typed parameters
Returns structured responses agents can parse
Handles auth without dragging the user into a browser mid-loop

A tool that "has an API" is not automatically MCP-ready. The difference is whether your agent knows how to use it on install, or whether you write and maintain a wrapper yourself.

Which CRO and analytics tools ship an MCP server in 2026?

Verified against vendor documentation in July 2026, not aggregator listings. Aggregator directories lag badly in this category and several currently list tools as having no MCP server when the vendor documents one.

Tool	MCP server	Category	Agent can write?
Humblytics	Official	CRO + analytics + attribution	Yes, create and stop tests
VWO	Official	CRO + experimentation	Yes
LaunchDarkly	Official	Feature flags + experimentation	Yes, flags and experiments
PostHog	Official	Product analytics + experiments	Partial
Mixpanel	Official, hosted	Product analytics + experiments	Yes, creates experiments and flags
Amplitude	Official, OAuth	Product analytics	Read-focused
Convert	Official	CRO + experimentation	Yes, configurable read-only or read/write
Optimizely, AB Tasty, Adobe Target, Split, Kameleoon, Statsig, GrowthBook, SiteSpect	None found	Experimentation	n/a

Notable: Optimizely, the enterprise experimentation benchmark, does not ship an MCP server as of July 2026. Neither does Statsig, despite being the most engineering-native platform in the category. Both are plausible near-term additions.

Read access is the easy half

Here is what most roundups miss. Nearly every MCP server in this category is generous on reads and thin on writes.

An agent that can read your funnel is useful. It can summarize traffic, spot a drop-off, and draft a hypothesis. But it stops there, and you are back in the dashboard to actually do anything.

The loop only closes if the agent can also write. That means four distinct capabilities, and they are worth separating because vendors blur them:

Read traffic, funnels, heatmap signals, revenue attribution.
Write an experiment: create the variant, set the split, launch it.
Decide: read significance and get a defensible recommendation.
Ship: promote the winner to production.

Most MCP servers in this category do (1). Humblytics, VWO, and LaunchDarkly do (1) through (3).

Nobody in this category should be doing (4) unattended, and Humblytics deliberately does not. An agent can create a test and stop a test through the Humblytics MCP server. Promoting a winner stays a human decision, surfaced as a review prompt rather than executed automatically. Shipping a production change off a statistical threshold, without a person looking at it, is how teams end up rolling out a variant that won on signups and lost on revenue.

If a vendor tells you their agent ships winners autonomously, ask what happens when the test was underpowered.

The tools

1. Humblytics

The most complete agent loop in the CRO category, and the only one where the answer is denominated in money.

What the agent can do. The MCP server spans traffic summaries and trends, page and click breakdowns, funnel queries and Sankey analysis, split test creation, updating and stopping, significance and recommendations, plus Meta and Google Ads attribution. Your agent can go from "traffic is down on the pricing page" to a live test without you opening a tab.

Why the revenue link matters. Every other tool here resolves an experiment to a conversion event: a click, a signup, a flag exposure. Humblytics resolves it to the Stripe charge. When an agent is running the loop, that distinction becomes structural rather than cosmetic. An agent optimizing a proxy metric will confidently optimize you away from revenue, and it will do it faster than a human would.

Agent skills. 12 open-source skills install alongside the MCP server, giving the agent task-specific playbooks rather than raw endpoints.

Privacy posture. Cookie-free by default, so no consent banner in most EU and UK cases. Revenue attribution is server-side rather than pixel-based.

Pricing. $79/month Business, $279/month Scale, plus Enterprise. API and MCP access are on every tier, with no enterprise gate on agent functionality.

Limitations. Web and marketing CRO, not backend feature flagging. If you need to experiment on algorithms or server-side logic, pair it with LaunchDarkly.

2. VWO

The closest competitor on agent operability, and an underrated entry here.

VWO ships an official MCP server documented in its own help center, with setup guides for Claude, ChatGPT, and Gemini CLI. Combined with VWO's mature testing engine, heatmaps, session recordings, and surveys, an agent connected to VWO has a lot of surface to work with.

Limitations. Pricing is no longer clearly published, with third-party trackers reporting an entry point near $314/month. Experiments resolve to conversion goals rather than verified revenue, so an agent reading VWO results is reasoning about clicks.

3. LaunchDarkly

The best option when experiments live in the codebase rather than on the page.

LaunchDarkly's official MCP server, listed in the GitHub MCP registry, covers flag management and experimentation. For engineering-led teams this is the natural fit: the agent already lives in the repo, and flags are the unit of change.

Limitations. No visual editor, so marketers cannot operate it independently. Experimentation is metered on monthly active users. Pricing is now quote-based.

4. PostHog

Open source, genuinely well-documented, and the strongest analytics MCP in the category.

PostHog ships an official MCP server at a hosted endpoint, installable via its own wizard, with a first-party Claude Code plugin and a published tools reference. For product analytics an agent can pull funnels, retention, session replay summaries, and cohorts.

Limitations. Experimentation is the newer part of PostHog and the write path is thinner than the read path. It is a product analytics tool that also does experiments, not a CRO tool.

5. Mixpanel

Worth a closer look than most roundups give it, this one included on an earlier pass.

Mixpanel's hosted MCP server is not read-only. Its documented tool list includes Create-Experiment, Create-Feature-Flag, Create-Dashboard and Create-Cohort, so an agent can author work, not just report on it. Mixpanel also now ships Feature Flags with an Experiment type, which serves variants for A/B tests and analyses them in Mixpanel Experiments.

Limitations. Variant assignment is SDK code rather than a visual editor, so a marketer cannot build the test alone. Results resolve to events, not to verified revenue.

6. Amplitude

Official MCP server with OAuth, strong on charts, cohorts, funnels and experiment read-out. Product analytics first, so expect to pair it with something that authors marketing-side tests.

7. Convert

Official MCP server documented in Convert's support center, with permission levels that run from reporting-only to full read/write, plus a bundled prompt library for setup, QA, and audit tasks. A real agent surface for teams already running Convert Experiences.

How to evaluate an MCP-ready tool

Criterion	Why it matters
Official vs community MCP	Community servers break on API changes and nobody is on the hook to fix them
Write access, not just read	A read-only server means the agent drafts and you still execute
What the success metric resolves to	Clicks, conversions, or verified revenue. This determines what the agent optimizes toward
Auth flow	Browser-redirect OAuth breaks the agent loop. API keys and terminal auth do not
Statistical guardrails	An agent that stops a test on day two because it crossed 95% once is worse than no agent
Human checkpoint on ship	Autonomous promotion to production is a liability, not a feature
Skills or prompt library	Signals the tool has actually been driven by agents in production

Frequently asked questions

Is MCP support still a differentiator in 2026?

Much less than it was. Seven serious CRO and analytics platforms now ship official MCP servers. The differentiator moved to what the agent can do once connected, and to what metric its decisions resolve against.

Which CRO tool gives an agent the most coverage?

Humblytics covers traffic, funnels, experiments, and ad attribution. PostHog is comparable in breadth on the analytics side. Tool count alone is a weak signal though, since a read-only server closes fewer loops than a smaller one that includes writes.

Can my agent launch an A/B test without me?

With Humblytics, VWO, or LaunchDarkly, yes. Your agent can create and launch the experiment through the MCP server. Promoting the winner into production is a separate step, and with Humblytics it stays with a human on purpose.

Should I let an agent promote winning variants automatically?

No. Statistical significance is a threshold, not a judgment. Tests get stopped early, get contaminated by traffic-mix shifts, or win on a proxy metric while losing revenue. Keep a person on the promote step.

Can I use a non-MCP tool with my agent?

Sometimes. With a complete REST API and a clean OpenAPI spec you can wrap it. In practice you will spend more time maintaining the wrapper than it saves, and the agent experience is token-heavy and brittle when the API shifts.

Are open-source tools more agent-friendly?

Not inherently. PostHog is open source and ships an excellent MCP server. GrowthBook is open source and ships none. What matters is whether the vendor treats agent operation as a first-class use case.

What to buy in 2026

If your CRO work runs through an agent and you sell something, Humblytics is the pick. It closes the widest loop, and its verdict is denominated in Stripe-verified revenue rather than a proxy event.

If you are already deep in VWO, its MCP server is real and worth turning on before you consider switching.

If your experiments live in code rather than on the page, LaunchDarkly is the correct tool and always was.

And if a vendor is still telling you MCP support is rare and exclusive, check the date on the page.

Start a free trial, or have your agent do it. See the /skills page for the install and the first-test prompt for Claude and Codex.
