PostHog MCP Server

PostHog is a full-featured product analytics platform that helps teams understand user behavior, run experiments, and manage feature rollouts. This MCP provider gives you access to PostHog's core analytics capabilities, experiment management, feature flags, surveys, and error tracking.

Core Capabilities

Analytics & Insights: Query event data, create and manage insights, run custom analytics queries to understand user behavior patterns. Access event definitions and property schemas to understand your data structure.

Experimentation: Create, manage, and analyze A/B tests and feature experiments. Get detailed results including metrics data, exposure statistics, and performance insights across variants.

Feature Management: Create, update, and delete feature flags to control feature rollouts and targeting. Manage flag states and configurations for gradual releases or targeted user segments.

User Research: Design and deploy surveys with various question types (open-ended, rating scales, multiple choice). Target specific user segments and analyze response patterns across your user base.

Error Monitoring: Track and investigate application errors, access error details, and monitor error trends across your project.

Domain Model

PostHog organizes data around projects within organizations. Events flow into projects and are analyzed through insights, experiments reference these events for success metrics, and feature flags control user experiences. The provider can switch between accessible organizations and projects as needed.

Key Considerations

Always test queries before creating insights to ensure they return expected data. When creating experiments, establish clear hypotheses and success metrics upfront. Feature flag changes can immediately impact user experience, so coordinate with your development team. Survey targeting and timing significantly affect response rates and data quality.

The provider includes extensive documentation resources covering error tracking implementation across different platforms and frameworks.
