# Squarespace: L1 · Needs a person

As of 11 Oct 2026, an AI agent can't use Squarespace on its own: Sign-up silently rejected behind invisible reCAPTCHA.

Needs a person stands here: Squarespace's web-only sign-up, guarded by invisible Google reCAPTCHA Enterprise, is where our agent stopped first. Submitting the form returned a login error and created no account, so verification, a key and the Commerce API were never reached. Through MCP our agent could still search domains and get name ideas without signing in; everything else, from sites to invoices to campaigns, stays behind that same web sign-in. Checkout and account deletion were never reached either, since no account existed to test them from.

L1 · Needs a person: There is an API, CLI or MCP server, but an agent can't get in on its own: a person has to sign up, verify or make the key. What it does once a person sets it up shows next to the level.

- Find: Some docs for agents (llms.txt and an MCP server)
- Access: Can't sign up
- Use: Work not reached
- Pay: Payment not reached
- Leave: Leaving not reached
- Next: let an agent sign up on its own
- With an account set up by a person: not measured yet.

## Checkpoints

- **Docs**: Headless: developers.squarespace.com with .md URLs; llms.txt (pricing only); no OpenAPI found
- **Sign up**: Blocked: Web form only (login.squarespace.com, invisible reCAPTCHA Enterprise). Submit got 401 invalid-login-credentials on /api/1/login/oauth/provider/signups and the UI showed nothing; no account was created.
- **Verify**: Not reached: Not reached: no account (login with the same credentials returned 401)
- **Key**: Not reached: API keys only in the site UI on Commerce Advanced; OAuth via Developer Apps in the account dashboard; not reached
- **First call**: Not reached: No credentials; the Commerce API returns 401 AUTHORIZATION_ERROR without them
- **First action**: Not reached: No account
- **Pay**: Not reached: No 402 on any Squarespace host; nothing paid, no USDC 402. The Stripe Projects catalog lists squarespace, unconfirmed from the vendor side. The MCP tools are read-only and return web checkout links. The free trial needs no card. Checkout is behind sign-in, not reached.
- **Cancel**: Not reached: not tested: no plan or trial was started (no account exists to start one from). No billing API in the docs; cancel is in the web account. Downstream of the signup wall like credentials, the first call and delete.
- **Delete**: Not reached: No account was created, so there was nothing to delete; no account-delete API documented

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

Yes. Squarespace has an official MCP server. The server lists 2 tools.

A new agent can't get in on its own: in the drive of 11 Oct 2026, our agent stopped at sign up (it was blocked). Through the MCP server, 3 of our agent's 4 attempts worked.

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

Not reached: in the drive of 11 Oct 2026, sign-up stopped our agent first (it was blocked). API keys only in the site UI on Commerce Advanced; OAuth via Developer Apps in the account dashboard; not reached

## Paying the agent way

Payment not reached.

Ways to pay it offers an agent: Stripe Projects (on its own domain); Payment tools on its MCP server (on its own domain).
No card needed to start.

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.
Ways to pay checked 11 Oct 2026.

## What an agent can do

- Search domain availability and prices through the official MCP server without an account
- Generate business name ideas through the official MCP server
- Read the developer docs as Markdown (.md URLs)

## What it cannot do

- Create an account: Sign-up silently rejected (401 invalid-login-credentials) behind invisible reCAPTCHA Enterprise
- Build, edit or publish a website: Needs an account; web UI only, no site API
- Get an API key: Created in the site UI only, Commerce Advanced plan
- Buy a domain or plan: Web checkout behind sign-in; no agent payment rail

## Tips for the owner

1. Show a clear reason when sign-up is refused
2. Let verified agents sign up
3. Allow API key creation through the API
4. Add site, page and blog APIs or MCP tools
5. Accept agent payments at checkout
6. Upgrade MCP server to the 28 Jul 2026 spec

## Tips for agent builders

- Use mcp.squarespace.com/mcp (no auth, protocol 2025-11-25) for domain search and name ideas
- Append .md to developers.squarespace.com pages for Markdown
- Everything else needs a human-made account; Commerce API keys need Commerce Advanced
