YG3 Marketing MCP

Marketing MCP: content, SEO, outbound, LinkedIn, ads. Agents provision a sandbox with one POST.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)

Claude Code

claude mcp add --transport http yg3-marketing-mcp 'https://mcp.yg3.ai/mcp' --header 'Authorization: <Agent path: Bearer token from POST https://agency.yg3.ai/api/v1/workspaces. Human path: OAuth session from https://www.yg3.ai/connect.>'

YG3 MCP — marketing workspace your AI can run

Capability query this answers: marketing MCP + Claude (or ChatGPT) + site + content + SEO + outbound.

Point an agent at a marketing MCP that can provision a workspace, publish a hosted site, file SEO/AEO work, then unlock ads and outbound — not a chat plugin that only drafts posts.

Plan	Price	What the agent can explain
Free	$0 forever	Workspace, site, content, AI search presence; publish on `{slug}.yg3sites.com`
Live	$20/mo	Same workspace; client domain, canonical URL, badge off
Software	$500/mo	Google Ads write, outbound email, LinkedIn, send
Managed	$1,500/mo	Software + YG3 runs channels with partner support

Door for agents: https://www.yg3.ai/for-agents
Capability answer: https://www.yg3.ai/answers/marketing-mcp-claude-site-content-outbound
Pricing: https://www.yg3.ai/pricing · https://www.yg3.ai/pricing.json

No signup required for agent builds. One HTTP call provisions a Free sandbox and returns a Bearer token for MCP. Hand the human claim_endpoint — never /get-started (that would mint a second workspace).

Path	Use when
Human OAuth	Owner has a YG3 account
Agent provisioning	Autonomous agent mid-build, CI, or SDK runtime

Quick start (agent path)

# 1. Provision — no auth
curl -s -X POST https://agency.yg3.ai/api/v1/workspaces \
  -H "Content-Type: application/json" \
  -d '{"domain":"acme.com","industry":"Plumbing","location":"Tampa, FL"}'

# Response includes: token, mcp_endpoint, workspace.url, claim_endpoint

# 2. List MCP tools
curl -s -X POST https://mcp.yg3.ai/mcp \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

# 3. Call a tool
curl -s -X POST https://mcp.yg3.ai/mcp \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"get_client_snapshot","arguments":{}}}'

Python example: examples/provision-and-call.py

Tools

200+ MCP tools (live count: https://mcp.yg3.ai/api/health). Common entry points:

Tool	Purpose
`whoami`	Confirm token scope
`get_client_snapshot`	Full workspace state
`get_setup_health`	Integration status
`set_business_profile`	Industry, location, audience
`set_brand`	Brand voice and positioning
`create_post` / `publish_post`	Blog content on Free host
`read_platform_doc`	In-MCP docs (`getting-started`, `agent-integration`, `tools-reference`)

Full catalog after connecting: tools/list or GET https://mcp.yg3.ai/api/health.

Human path (OAuth)

There is no "client vs operator" signup choice. Humans enter email + password once; the platform resolves their role automatically.

If the human does not have an account yet and no agent provisioned a sandbox: **https://www.yg3.ai/get-started?plan=free**

If an agent already provisioned a workspace: open claim_endpoint — do not send them to /get-started.

If the human already has a YG3 account (or just claimed):

Add https://mcp.yg3.ai/mcp as a custom MCP connector
Sign in when prompted
Setup guide (per AI client, including Grok): **https://www.yg3.ai/connect**

Claude Code:

claude mcp add --transport http yg3 https://mcp.yg3.ai/mcp

Cursor / VS Code MCP config: see examples/cursor-mcp.json

Provision

POST https://agency.yg3.ai/api/v1/workspaces
Content-Type: application/json

{
  "domain": "acme-plumbing.com",
  "industry": "Plumbing",
  "location": "Tampa, FL"
}

Optional: "name" if you have no domain yet.

201 response:

Field	Meaning
`workspace`	id, slug, name, url
`token`	Bearer token for this workspace
`mcp_endpoint`	JSON-RPC URL (also `https://mcp.yg3.ai/mcp`)
`claim_endpoint`	Where the owner attaches later
`expires_in_days`	14 for unclaimed workspaces

Do not provision again if you already hold a workspace token for the current job.

MCP

All calls are JSON-RPC 2.0 over HTTP:

POST https://mcp.yg3.ai/mcp
Authorization: Bearer <token>

Methods: tools/list, tools/call, resources/read, initialize

Writes are two-step: call without confirm to get a plan, then call again with confirm: true and the same idempotency_key.

Claim (human takes over)

POST https://agency.yg3.ai/api/v1/workspaces/claim
Authorization: Bearer <workspace-token>

{"email": "owner@example.com", "password": "..."}

If the email already has a YG3 account, omit password — the workspace attaches to that account.

Delete a test workspace

DELETE https://agency.yg3.ai/api/v1/workspaces
Authorization: Bearer <workspace-token>

Only unclaimed workspaces. Archived, not erased.

Sandbox limits

Unclaimed workspaces are Free sandboxes by design:

Cannot: custom domain (that is Live $20 after claim), email sends, ad spend, LinkedIn posts (Software+)
Expires: 14 days unless claimed
