Connect PostHog to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent lists your projects, dashboards and saved insights, reads an insight's latest result and recent events, and can mark a release on your charts with an annotation. It signs in with your own PostHog account and sees only the projects it can.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect PostHog after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## Ask what moved. Get the insight behind it

Your agent finds the dashboard, reads the insight's latest result, and checks recent events. You get the change and where it came from.

You ask your agent: "Open our Growth dashboard in PostHog. Read the weekly signups insight and recent signup events, and tell me what changed last week. Do not create annotations."

It calls CoreSpeed:

- `posthog__list_dashboards`: ok, 280 ms
- `posthog__get_insight`: ok, 455 ms
- `posthog__list_events`: ok, 610 ms

It reads from: PostHog.

## Questions

### Which PostHog regions work?

PostHog US Cloud projects work today. EU Cloud accounts are not supported yet.

### Can the agent change my PostHog project?

It can create an annotation, a dated marker on your charts, as a separate tool call. It cannot edit insights, dashboards or events.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
