For agents

Marketing ops from any agent build.

Provision a YG3 workspace with one POST — no signup, no OAuth, no human in the loop. You get a Bearer token and 200+ MCP tools for content, SEO, outbound, LinkedIn, and paid ads. Hand the workspace to a human when they are ready.

Provision in one callbash
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"}'
MCP

Call tools with the token.

Same server humans reach through OAuth. JSON-RPC over HTTP.

Example tool callbash
curl -s -X POST https://mcp.yg3.ai/mcp \
  -H "Authorization: Bearer $YG3_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_client_snapshot","arguments":{}}}'

What unclaimed workspaces can do.

Free tier by design. Real work inside YG3; nothing reaches the outside world until claimed and upgraded.
