Valid

Valid is an AI-native advertising agency that grows consumer companies through an end-to-end performance marketing offering, combining AI-generated performance creative (20+ ads per month, moving from concept to launch in about three days), brand-specific AI-influencers with organic followings, and managed media buying across Meta, TikTok, Google, Snap, and AppLovin. Every managed client also receives the "Chat With Your Ads" MCP server — a live, first-party Model Context Protocol endpoint at mcp.valid.co that lets an agent query the whole ad account in plain English. That MCP surface is customer-gated rather than public: it is protected by an OAuth 2.1 authorization code flow with PKCE and RFC 7591 dynamic client registration, and it correctly serves the full RFC 9728 / RFC 8414 discovery chain, but Valid publishes no developer portal, no documentation, no OpenAPI, and no tool catalog, so the capability surface is invisible without a client account. Valid is backed by Canaan Partners and based in San Francisco, California.

Valid publishes 1 API on the APIs.io network. Tagged areas include Company, Advertising, Marketing, Artificial Intelligence, and Creative.

Valid’s developer surface includes support and 13 more developer resources.

  description: A live first-party Model Context Protocol server that lets a Valid managed-service client query their whole
    advertising account — spend, channels, creative performance, attribution — in plain English from an MCP-capable agent.
    Speaks JSON-RPC over streamable HTTP and is protected by an OAuth 2.1 authorization code flow with PKCE, refresh tokens
    and dynamic client registration, with the full RFC 9728 protected-resource and RFC 8414 authorization-server discovery
    chain published anonymously. The tool catalog itself is auth-gated; an anonymous tools/list returns 401.
