How do I create a PostHog Personal API Key?

Log in to [**PostHog**](https://app.posthog.com), click your profile icon > **Personal API keys**, then **+ Create a Personal API Key**. Give it a label, select the required scopes and copy the key immediately — it won't be shown again after page refresh.

Can I toggle feature flags via the agent?

Yes! Use `create_feature_flag` to add new flags, `update_feature_flag` to modify existing ones (name, description, enabled status), and `delete_feature_flag` to remove them. You'll need the numeric flag ID from `list_feature_flags` for update and delete operations.

What's the difference between events and persons?

**Events** are actions that happen in your product (pageviews, button clicks, purchases). **Persons** are the users who perform those actions, identified by distinct_id. Events are linked to persons, so you can see what actions a specific user has taken. Use `list_events` to browse activity and `get_person` to see a user's profile.

Can I use this with a self-hosted PostHog instance?

Yes! The tools default to `https://app.posthog.com` for the US cloud, but you can set the `host` parameter to your self-hosted instance URL (e.g. `https://posthog.yourcompany.com`). EU cloud users should set the host to `https://eu.posthog.com`.

PostHog Alternative + Cursor FAQ

Common questions about integrating PostHog Alternative MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
