# Keryx

> Create advertising ideas and finished ads for a customer's website or app. Work is saved in the same Keryx account and workspace used by the website.

## Connect

- [MCP connection guide](https://keryxmarketing.com/mcp): supported client setup, signup and sign-in, permissions and capabilities.
- Remote MCP endpoint: https://app.keryxmarketing.com/mcp (Streamable HTTP, OAuth).
- [API and first-ad guide](https://app.keryxmarketing.com/developers): the shared product discovery and creative workflow.
- [OpenAPI](https://app.keryxmarketing.com/api/openapi.json): current HTTP operations and request schemas.

Start the client's OAuth connection before signing up. The browser offers Google or email/password signup and sign-in, including email verification and account linking. The user completes these steps on Keryx and approves the connection; passwords and verification codes stay out of chat. Account creation resumes the pending connection. Connector installation or enabling tools may require a client action.

## First ad

Use the customer's product website or store link, asking for it if missing. The Keryx website describes the service; it is not automatically the product to advertise. After connection, use the available tools to discover or reuse the product, create an idea and finished artwork, and return the saved ad's preview and Keryx link. The agent can choose a creative approach from the customer's request and product context.

Creative work uses the same account credit and prices as the website. Read accepted work's saved progress. If a response is lost, repeat the exact request and idempotency key; do not create another paid attempt automatically. Campaign launches and ad-budget spending are outside this MCP.
