TikTok launches an external ad network across nearly 400k apps

TikTok is expanding its advertising business beyond the TikTok app. The new TikTok Ad Network, initially available to US advertisers through TikTok Ads Manager, lets campaigns extend across what the company describes as a premium network of nearly 400,000 third-party apps worldwide, with placement and brand-safety controls built into the system.

At the same time, TikTok is pushing deeper into AI-assisted advertising through its TikTok for Business Model Context Protocol, or MCP. The system allows AI agents to connect directly with TikTok’s advertising tools for tasks such as campaign creation, creative management, performance reporting, and optimization. TikTok says advertiser use of the MCP for campaign activation and management has increased by more than 200% since launch, and connectors are now available across platforms including Claude, Kimi, Manus, Perplexity, Replit, Snowflake, and others.

TikTok is also introducing more agentic commerce tools. Shopping Assistant acts as a conversational shopping agent that can answer questions about products, sizing, shipping, and availability, while Buy Direct enables purchases from brands without leaving the For You feed. A separate Agentic Leads product uses AI-guided conversations to capture and qualify prospective customers.

There are already examples of advertisers using the MCP for larger automated workflows. In a TikTok case study, game developer Westwon reported creating more than 680 ads in under an hour using an AI-assisted MCP workflow, compared with roughly three minutes per ad manually. TikTok says this represented an up-to-45-times improvement in creation speed, although those results are brand-reported rather than independently verified.
