How do I connect this MCP to my PostHog account?

You need to provide your PostHog Personal API Key during the setup process on Vinkius. Once connected, you can use it in any MCP-compatible client.

Can I use this with Cursor or VS Code?

Yes. This MCP works with any compatible client, including Cursor, VS Code, and Claude.

Is it safe to manage feature flags through an AI agent?

The agent uses your PostHog API key to perform actions. You maintain full control over which capabilities the agent can invoke.

What happens if I delete a feature flag through the agent?

Deleting a feature flag is irreversible. It removes all associated targeting conditions, release conditions, and experiment data.

Can I see specific user properties?

Yes. You can use the agent to look up individual users and view their specific properties and activity timelines.

How do I create a PostHog Personal API Key?

Log in to PostHog, 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 capabilities 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.

MCP VERIFIED · PRODUCTION READY · VINKIUS GUARANTEED

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

How to manage feature flags

One connector, every AI

PostHog works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put PostHog to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of PostHog, so you can see the experience inside your AI.

It does not authenticate your account with PostHog. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
