'UTAGE,' a marketing automation (MA) system operated by Fountain Inc. (Headquarters: Minato-ku, Tokyo), released an API and MCP (Model Context Protocol) on April 4, 2026, enabling integration with external systems and generative AI agents.
With this support, it becomes possible to directly operate UTAGE's funnel functions from Anthropic's AI assistant 'Claude' and the AI coding tool 'Claude Code,' allowing for the automated creation of landing pages (LPs) and sales pages. UTAGE stands as a pioneer among domestic SaaS marketing tools by supporting MCP.
## Background of Release: Marketing Operations Transformed by AI
With the rapid evolution of generative AI and AI agents, the automation of marketing operations is becoming a reality. Since the advent of generative AI like ChatGPT and Claude, there has been significant progress in creating advertising copy, generating newsletter texts, and streamlining data analysis.
Furthermore, entering 2026, the explosive spread of the open-source personal AI agent 'OpenClaw' and the emergence of AI business automation tools for non-engineers like Anthropic's 'Cowork' have shifted AI from a phase of 'dialogue' to 'execution.' The concept of 'vibe coding'—building apps and pages simply by instructing an AI without writing code—is spreading, and an era where agent-type AIs execute tasks autonomously is arriving.
However, in the marketing domain, automating the execution phase—such as 'actually operating a tool to build an LP,' 'setting up a step-email scenario,' or 'building a funnel for seminar attendance'—still heavily relied on manual work. This was because many MA and LP creation tools are no-code tools designed for GUI operation, lacking the APIs and interfaces for AI agents to operate them programmatically.
UTAGE is a domestic MA offering all-in-one features for sales funnel building, email delivery, LINE delivery, payments, membership sites, and customer management. It has been adopted by over 17,000 companies cumulatively and supports the marketing activities of over 1 million users. It is widely used, particularly in the domain of online businesses such as online courses, content sales, and seminar attraction, highly evaluated as a marketing tool that realizes customer attraction systematization and operational efficiency.
This release of the API and MCP is an initiative to evolve UTAGE into a marketing platform that can be operated by AI agents and autonomous agents, while maintaining its ease of use as a no-code MA tool.
## What is MCP (Model Context Protocol)?
MCP is an open protocol proposed by Anthropic to connect AI models with external tools. Previously, for an AI to operate external SaaS or web services, individual integration development was required for each service. MCP serves as a standard specification to solve this issue; major tech companies like Google, Microsoft, and Salesforce are also developing MCP-compliant tools, and alongside Google's A2A (Agent-to-Agent) protocol, it is becoming an industry standard for AI integration. MCP is positioned as a core technology for realizing the 'multi-agent systems' selected by Gartner as a strategic technology trend for 2026.
UTAGE has now implemented functionality as an MCP server. This allows generative AI tools like Claude and Claude Code to connect to UTAGE's MCP server and execute marketing measures based solely on human natural language instructions. As the trend of 'autonomous agents'—where AI agents autonomously judge and execute tasks—accelerates, UTAGE expands the possibilities of MCP utilization as its execution foundation.
