What PostHog MCP is

The PostHog MCP server is a free hosted endpoint at https://mcp.posthog.com/mcp. It lets agents read and write across PostHog products, such as analytics and SQL, dashboards, experiments, feature flags, surveys, session replay and error tracking. The code now lives in the PostHog monorepo under services/mcp.

Security notes from the maintainers

Some tools use LLMs internally, may bill as PostHog AI spend and need AI data processing enabled in org settings

Review the source before granting an agent access to credentials or production systems. We document what the maintainers state; we do not audit code.

Limitations

Standalone PostHog/mcp repo is moved into the PostHog monorepo
