# Postiz: L2 · Gets in

As of 2 Oct 2026, an AI agent gets into Postiz on its own.

Gets in on its own, L2 · Gets in. Our agent signed up through the web form and confirmed by email, no CAPTCHA shown. It called MCP initialize, listed tools, and read the integration list without a subscription. Sign-up and the first call held up, but the public API and CLI answered "No subscription found," and first_action stopped: there is no free plan, so no channel can be connected and nothing can be created. Paying needs a card for the trial, which our agent does not carry, so it never started a plan or reached checkout.

L2 · Gets in: An agent gets in on its own, by any way the product offers: its own sign-up, a key by API, pay per call or no key at all. It does less than half the core work, or the work isn't measured yet.

- Find: Docs for agents (llms.txt, an OpenAPI and an MCP server)
- Access: Sign-up in a browser
- Use: Work not reached
- Pay: Card checkout
- Leave: Nothing to cancel (Can't delete its account)
- Ways in: Sign-up in a browser
- Next: let a trial or free plan reach the core features
- With an account set up by a person: not measured yet.

- Not measured in this drive: Holds up, Docs match

## Who gets in

Sign-up page checked 12 Oct 2026. Signed agents: the ones Cloudflare verifies.

## Checkpoints

- **Docs**: Headless: llms.txt on postiz.com and docs.postiz.com, llms-full.txt, every page as .md with embedded OpenAPI.
- **Sign up**: In a browser: Web form only (no documented headless sign-up); no visible CAPTCHA.
- **Verify**: In a browser: Activation mail arrived in ~1 min; link opened in the browser logs you in.
- **Key**: In a browser: Documented MCP OAuth with dynamic client registration: DCR and token exchange headless, one consent click in the logged-in browser. API key itself not shown without a subscription.
- **First call**: Headless: MCP initialize/tools/list (19 tools)/integrationList worked without a subscription; public API and CLI return 401 'No subscription found'.
- **First action**: Blocked: No free plan: the whole app is replaced by a plan picker; the 7-day trial needs a card in Stripe embedded checkout. No channel can be connected, so nothing can be created.
- **Pay**: Not tried: No 402/x402/MPP/L402, no agent-commerce discovery, no billing API. The trial requires a card (authorisation check) in Stripe embedded checkout with Stripe's invisible hCaptcha; we have no card.
- **Cancel**: Not needed: Nothing to cancel: our agent started no paid plan.
- **Delete**: Needs a human: Docs: no self-serve account deletion; email support@postiz.com. Not sent (no messages to real people); the account and its OAuth grant remain (Approved Apps page is behind the paywall).

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

Yes. Postiz has an official MCP server.

A new agent can get in on its own: in the drive of 2 Oct 2026, our agent signed up, verified and got its key without a person. Through the MCP server, 2 of our agent's 3 attempts worked.

## How does an AI agent get a Postiz API key?

In the drive of 2 Oct 2026, our agent got its Postiz API key in a browser, without a person. Documented MCP OAuth with dynamic client registration: DCR and token exchange headless, one consent click in the logged-in browser. API key itself not shown without a subscription.

## Paying the agent way

Card checkout.

Ways to pay it offers an agent: Stripe Checkout.
Its trial asks for a card.

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.
- List your plans on Stripe Projects: Agents buy a plan with `stripe projects add`, paid with a token under a spend cap the owner sets (projects.dev).
- Let a trial start without a card: An agent can try the product before anyone hands it a card; take the card when it buys.
From the drive of 2 Oct 2026.

## What an agent can do

- Read complete agent-oriented docs (llms.txt, llms-full.txt, OpenAPI per endpoint)
- Register an MCP OAuth client headless (DCR) and get a token after one consent click
- List the MCP tool set

## What it cannot do

- Connect a channel, schedule or publish any post: No free plan; the 7-day trial requires a card, so API/CLI return 401 'No subscription found' and the UI is replaced by the plan picker
- Start the trial: Card required in Stripe embedded checkout; we have no card
- Delete the account: No self-serve deletion; support email only

## Tips for the owner

1. Offer a no-card trial or free tier
2. Add an agent-payable checkout rail
3. Enforce subscription on the MCP server
4. Add self-serve account deletion
5. Make cancel available via API

## Tips for agent builders

- Use the hosted MCP (https://mcp.postiz.com/mcp-oauth-dynamic): it supports dynamic client registration and PKCE, so no API key copy-paste is needed; consent needs a logged-in browser once.
- Without an active subscription (trial needs a card) the API and CLI answer 401 'No subscription found': have a human start the trial first.
- The documented connect-channel route is GET /public/v1/social/{integration}, not /integrations/connect/{integration}.
- Self-hosted Postiz has no subscription gate if you can run Docker.
