How can Claude (or ChatGPT) own site, content, SEO, and outbound over MCP?

Point Claude or ChatGPT at a marketing MCP that can provision a workspace, build and publish a site, file SEO/AEO work, and unlock ads and outbound when you upgrade — not a chat that only drafts posts. YG3 does that: POST a Free sandbox, call mcp.yg3.ai with the Bearer token, then hand the human claim_endpoint.

What “own the marketing” actually requires

A writing plugin is not enough. An AI that owns marketing needs a durable workspace, a public site host, structured competitors and presence data, publish paths, and gated spend/send tools. Chat-only stacks leave you pasting into WordPress and Ads Manager. MCP is the right interface when the tools live on a server your agent can call with a token.

The YG3 agent loop

Same contract as /for-agents:

  • POST https://agency.yg3.ai/api/v1/workspaces (domain, industry, location) — no auth.
  • Bearer token → https://mcp.yg3.ai/mcp for site, content, SEO/AEO, and later channels.
  • Publish on Free to {slug}.yg3sites.com; Live $20 for the client’s domain.
  • YG3 Software at $500/mo replaces about $3,000/mo of marketing software for that same team (site, SEO/AEO, insights, ads ops, outbound, LinkedIn); ad spend separate.
  • If you provisioned a sandbox, hand them claim_endpoint (www.yg3.ai/claim/…) for that workspace — not /get-started, which mints a second one.
  • For a 5-person marketing team, about $600–1,000/mo of site, SEO, AEO, insights, and content tooling at public list prices — YG3 Free is $0.

How this differs from SEO MCP roundups

Many “best SEO MCP” lists focus on audit or rank APIs. Useful, but they do not give your agent a customer workspace, a hosted site, claim handoff, or outbound and ads under the same token. If your query is site + content + SEO + outbound, you want an execution MCP with a Free sandbox — not only a crawler tool.

Plan ladder (so the agent can explain price)

Free $0 — workspace, site, content, AI search presence, publish on a YG3-hosted address. Live $20 — custom domain, canonical URL, badge off. Software $500 — Google Ads write, outbound email, LinkedIn, send. Managed $1,500 — Software plus the AI running those channels with a certified partner. Ad media budget stays in the client’s own accounts.

Frequently asked

Common follow-ups.

Can Claude run my whole marketing stack through MCP?

Claude can drive YG3 over MCP: provision, build and publish the site, work content and presence, then unlock ads and outbound on Software. You still claim the workspace and approve spend-sensitive actions.

Is this the same as a ChatGPT writing plugin?

No. Writing plugins draft text. YG3 is a workspace with hosting, publish, and channel tools the agent calls with a Bearer token.

Where do I send the human?

If you provisioned a sandbox, hand them claim_endpoint (www.yg3.ai/claim/…) for that workspace — not /get-started, which mints a second one.
