Independent review. IonBin has no partnership with PostHog and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Product analytics, session replay, feature flags, experiments and a data warehouse in one place, with an official MCP server so agents can query product data directly.
PostHog describes itself as a single place to ingest, store and query product and company data: analytics, replays, errors and logs, plus third-party data from 900+ sources. source ↗
PostHog runs a hosted MCP server that works with any MCP-compatible client. Its docs name Claude Code, Claude Desktop, Cursor, Codex, VS Code, Windsurf and Zed, and say connecting and calling tools is free while some tools use LLM credits. source ↗
PostHog's free tier resets monthly and includes 1M analytics events, 5K session recordings, 1M feature-flag requests and 100K exceptions. Usage stops at the free limits unless you add a card. Checked 2026-10-17. source ↗
Connecting to the PostHog MCP server and calling its tools is free, but some tools use LLMs internally and may be billed as PostHog AI spend; those are available only when AI data processing is enabled. source ↗
How PostHog connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Confirmed Claude Code and Claude Desktop setup guides PostHog docs ↗Claude (incl. Claude Code) MCP docs ↗ | Confirmed Claude (incl. Claude Code) can run code; PostHog publishes an API. PostHog API ↗Claude (incl.

Claude Code) browser docs ↗ | Confirmed Export from PostHog, then works on the files in your project; chat accepts attachments Claude (incl. Claude Code) docs ↗ |
| OpenAI Codex | Confirmed Named as a supported client PostHog docs ↗OpenAI Codex MCP docs ↗ | Confirmed OpenAI Codex can run code; PostHog publishes an API.

| Google Antigravity | Not documented PostHog has an official MCP server and Google Antigravity supports MCP, but PostHog's docs don't name this pairing. Auth setup may differ. PostHog MCP docs ↗Google Antigravity MCP docs ↗ | Confirmed Google Antigravity can run code; PostHog publishes an API. PostHog API ↗Google Antigravity docs ↗ | Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗ | Confirmed Export from PostHog, then works on local projects and worktrees Google Antigravity docs ↗ |
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.

Via its official MCP server, from MCP-capable platforms such as ChatGPT, Claude, Gemini (Google), Google Antigravity, OpenAI Codex.
Via its API, through automation hubs: Gumloop, Make, n8n, Zapier.
No long-form review yet. Verdict is based on research, not hands-on testing.
Google's free tool for seeing how your site is indexed and which queries bring visitors from Google Search. It has an official API and a daily bulk export to BigQuery; Google has not documented an official MCP server.
