}Frequently asked questions
How do I connect PostHog to Windsurf?
You need two things: (1) connect PostHog to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Windsurf using the setup shown above. Once both are done, Windsurf can query your PostHog data directly.
What PostHog data can Windsurf access?
Windsurf can access any data available through your PostHog connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.
Is my PostHog data sent to Windsurf's servers?
Query results are returned to Windsurf as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.
Do I need a Sequel account?
Yes. You need a Sequel account to connect PostHog and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to PostHog and generate an API key from Settings → API Keys.
Can I connect multiple PostHog accounts?
Yes. Sequel supports multiple connections of the same type. If you have multiple PostHog accounts or properties, add each as a separate connection in Sequel. Windsurf will be able to query all of them.
