Can an AI agent use PostHog?

Q: Can an AI agent pay for PostHog?

Payment not reached. Free plan needs no card; paid is pay-as-you-go from the billing page with a card in Stripe. No 402 anywhere (no x402/MPP/L402 headers, no x402./mpp./agents. hosts, no /.well-known/ucp, not in the x402 Bazaar or mpp.dev). projects.dev lists PostHog as a Stripe Projects provider, not confirmed (no Stripe account). From docs only: no account to reach billing.

As of 3 Oct 2026, an AI agent can't use PostHog on its own: Turnstile on sign-up; wizard sign-up refused (403).

Pay for a paid plan as an agentupgrading happens on a billing page behind the same account wall, through a card, not an automatic payment

Needs a person

No. Sign-up: needs a human. Documented headless sign-up (wizard provision / --signup over the provisioning API) answered 403 'Account creation is not enabled for this partner' in US and EU. The web form ends in a visible Cloudflare Turnstile 'Verify you are human' on the last step.

Official server · a new agent can't get in alone

Does PostHog have an MCP server, and can an agent connect to it?

Yes. PostHog has an official MCP server. The server is hosted, lists 1083 tools and signs an agent in with OAuth.

A new agent can't get in on its own: in the drive of 3 Oct 2026, our agent stopped at sign up (it needs a person).

What would let agents pay on their own

Accept x402 or MPP on your API. Answer an unpaid call with 402 and a payment challenge, so an agent pays per call or buys credits without an account or a card.Step-by-step guide

No 402 anywhere (no x402/MPP/L402 headers, no x402./mpp./agents. hosts, no /.well-known/ucp, not in the x402 Bazaar or mpp.dev). projects.dev lists PostHog as a Stripe Projects provider, not confirmed (no Stripe account).

How an agent connects · 6 tips

/api/tools/posthog.json /tools/posthog.mdMCP get_tool {"slug":"posthog"}

Start at https://posthog.com/llms.txt: every docs page and every API operation has a .md page
The OpenAPI spec is public at https://us.posthog.com/api/schema/ (17 MB)
`posthog-cli api tools / search / info` lists the MCP tool catalog with input schemas, no key needed
Once a human has an account, `posthog-cli login` gives a device-style code flow; or set POSTHOG_CLI_API_KEY and POSTHOG_CLI_PROJECT_ID
Capture answers 200 Ok even for a wrong project token: check events landed with a read call
Private API on us.posthog.com, public capture/flags on us.i.posthog.com; EU uses eu. hosts

DocsHeadlessllms.txt with every docs page as Markdown (.md and Accept: text/markdown), public OpenAPI 3.1.0 at us.posthog.com/api/schema/, MCP tools reference, auth.md manifest.
Sign upNeeds a humanDocumented headless sign-up (wizard provision / --signup over the provisioning API) answered 403 'Account creation is not enabled for this partner' in US and EU. The web form ends in a visible Cloudflare Turnstile 'Verify you are human' on the last step.
VerifyNot reachedNo account, so no verification mail (inbox empty).
KeyNot reachedRoutes exist (OAuth with DCR/CIMD and PKCE, posthog-cli device-style login, personal API keys in the UI) but all need a signed-in account. DCR itself worked headless (201).
First callNot reachedNo credential. Public capture with a made-up project token answers 200 Ok, which proves nothing.
First actionNot reachedNo credential, nothing created.
PayNot reachedFree plan needs no card; paid is pay-as-you-go from the billing page with a card in Stripe. No 402 anywhere (no x402/MPP/L402 headers, no x402./mpp./agents. hosts, no /.well-known/ucp, not in the x402 Bazaar or mpp.dev). projects.dev lists PostHog as a Stripe Projects provider, not confirmed (no Stripe account). From docs only: no account to reach billing.
CancelNot reachedNo plan was started. OpenAPI has POST /api/billing/deactivate/ without a description.
DeleteNot reachedNo account was created. OpenAPI lists DELETE /api/users/{uuid}/ and DELETE /api/organizations/{id}/, not checked against an account.
