PostHog MCP Server — questions
Answers built from our own checks of this server.
Why is there no tool list for PostHog MCP Server?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is PostHog MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 72 ms. The bar chart above shows every period we have measured.
How do I connect PostHog MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own key or an OAuth login: it refuses anonymous clients.
Does PostHog MCP Server need an API key?
Yes. Every time we knock, PostHog MCP Server answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is PostHog MCP Server?
It answers our handshake in 72 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is PostHog MCP Server open source?
Yes — it is published under the NOASSERTION licence, written in Python, 37 483 stars on GitHub and 3298 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
