Best When

You want open-source product analytics with MCP server support and the option to self-host for data control.

Avoid When

You need enterprise SLA guarantees without self-hosting expertise or a pure marketing automation platform.

Use Cases

• Querying analytics events and insights via MCP server from agents
• Evaluating feature flags in backend services
• Capturing custom events from agent workflows
• Fetching user cohorts and properties for targeting
• Running A/B test experiments and reading results via API

Not For

• Teams needing on-premise hosting without engineering resources (self-hosted needs maintenance)
• Pure infrastructure/ops monitoring
• Teams needing pre-built marketing automation (use Segment + downstream tools)

Known Gotchas

⚠ MCP server is community-maintained and may not cover all API endpoints
⚠ Feature flag evaluation requires distinct_id which must match user identity system
⚠ Self-hosted instances need manual version updates - can drift from cloud API behavior
⚠ HogQL (PostHog's SQL dialect) has limitations vs standard SQL for complex queries
⚠ Event ingestion is asynchronous - newly sent events not immediately queryable
