What is the VWO MCP Server?
Connect your VWO (Visual Website Optimizer) account to any AI agent and take control of your experimentation and feature rollout workflows through natural conversation.
What you can do
- Optimization Campaigns — List and monitor active A/B tests and personalization campaigns directly from your agent
- Feature Management — List all feature flags and toggle their status across different environments for instant rollouts
- Experiment Results — Retrieve statistical results for any campaign, including performance metrics and significance levels
- Conversion Tracking — Browse conversion goals and KPIs being tracked to understand your optimization impact
- Audience Segmentation — List pre-defined segments to see how you are targeting different user groups
- Environment Control — Manage features across staging, production, and other configured VWO environments
How it works
1. Subscribe to this server
2. Enter your VWO API Token and Account ID
3. Start managing your experiments and feature flags through Claude, Cursor, or any MCP-compatible client
No more jumping between experiment dashboards to check test results. Your AI agent becomes your optimization engine.
Who is this for?
- Growth Managers — monitor experiment results and statistical significance without manual data exports
- Product Managers — manage feature rollouts and toggle flags across environments during launches
- Data Analysts — quickly surface conversion goal metrics and audience segment performance
- CRO Specialists — audit active campaigns and identify optimization opportunities through simple chat commands

Frequently asked questions
Can I check the winning variation of an A/B test through the agent?
Yes. The get_campaign_results tool allows your AI agent to pull detailed performance metrics for any experiment, showing improvement percentages and statistical significance for each variation compared to the control.
Is it possible to enable or disable feature flags via chat?
Absolutely. Using the toggle_feature_flag tool, you can instruct your agent to enable or disable any feature flag for a specific rollout or emergency kill-switch scenario, ensuring fast control without opening the VWO dashboard.
How can I see what conversion goals are being tracked for my campaigns?
You can use the list_conversion_goals tool to retrieve all metrics and KPIs (like clicks, form submissions, or revenue) currently being monitored in your VWO account.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query VWO tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
