Integration · PostHog
PostHog combines product analytics, experiments, feature flags, surveys, session replays, error tracking, and LLM analytics in one platform.
The MCP surface is the largest of any vendor in this catalog: more than two hundred tools across the full product. Use the ?features= query parameter to scope the connection to just the tools the agent needs, so context windows stay tight and tool selection stays accurate.
What you can do via MCP
“How many users completed signup in the last 7 days, broken down by day?”
Issues a HogQL query against the events table, returns a daily count series, and offers to chart it.
“Create a feature flag 'new-checkout' enabled for 20% of users.”
Creates the flag with a percentage rollout filter, returns the key and SDK snippet for the client integration.
“Pull the experiment results for pricing-page-v2 and recommend whether to ship.”
Fetches results, surfaces lift and confidence interval, and ships a ship/iterate recommendation grounded in the primary metric.
“List my session recordings from the last hour where users hit a 404.”
Filters session recordings by network errors and recency; returns a triage list ordered by user impact.
“Run a HogQL query: SELECT count() FROM events WHERE event = 'signup' AND timestamp > now() - INTERVAL 7 DAY”
Executes the raw HogQL, returns the result, and offers to save it as a saved insight.
Scoping the connection to flags and experiments only. The ?features= filter keeps the tool list short so the agent picks the right tool reliably.

CLI alternative
PostHog has a comprehensive REST API for programmatic integration outside an agent runtime. For AI-driven analytics and feature work the MCP is the right interface. There is no separate PostHog CLI for the AI flow; the MCP plus the REST API cover both modes.
Pairs with these skills
This integration pairs with the forthcoming experiment-design, experimentation-analytics, feature-flagging skills. The skill landing pages and SKILL.md sources land in subsequent dispatches; cross-link hyperlinks are added when the skill pages ship.
