GMO Sign Launches MCP Server for the AI Agent Era, Enabling Secure and Flexible Integration with Business Tools. [GMO GlobalSign HD]

GMO GlobalSign Holdings, Inc. (President and CEO: Mitsuru Aoyama; hereinafter 'GMO GlobalSign HD') has announced the launch of an MCP server for its electronic contract service, 'GMO Sign,' enabling secure and seamless read/write access between AI and various business services. Following demo experiences and early registration at its booth during the 'Legal & Compliance EXPO' held at Tokyo Big Sight from June 17 (Wed) to 19 (Fri), 2026, general availability is scheduled for autumn 2026. This will enable secure data integration between external LLMs (large language models) and AI agents (autonomous AI that performs tasks by automatically selecting various services without detailed human instructions) and SaaS systems (groupware, document management, workflow, etc.) adopted by enterprises and local governments, allowing for more flexible automation of contract-related business processes.

[Background: Meeting the Demand for Safe and Flexible AI Services Amid Rapid Growth of the AI Agent Market]

The global expansion of AI usage has led to rapid growth in the AI agent market, which is projected to reach $7.92 billion in 2025, $11.55 billion in 2026, and approximately $294.66 billion by 2035 (※1), according to Precedence Research. Japanese enterprises and local governments are now urgently required to prepare for the AI agent era.

At the same time, as AI adoption grows, incidents such as data breaches caused by improper services or usage methods are increasing. Enterprises and public institutions therefore require environments that enable safe AI utilization.

GMO Sign has now become capable of rapidly providing enterprises and local governments with a secure and flexible environment to respond to the AI agent era by combining 'JOINT AI Flow byGMO'—an advanced domestic MCP construction platform with API connectors provided by GMO AI Connect Co., Ltd. (formerly Strategit Inc., hereinafter 'GMO AI Connect'), which became a consolidated subsidiary of GMO GlobalSign HD in April this year—with its own authentication security technology. This platform enables cross-integration of diverse business systems such as generative AI, SaaS, and on-premises systems.

GMO Sign aims to expand its business scope toward becoming an 'AI Contract Business Platform' that supports the entire contract-related process, including contract automation, document management, and approval workflow integration using AI agents, with a continued focus on improving user convenience.

[About GMO Sign's MCP Server Offering]

MCP (Model Context Protocol) is a communication standard proposed by Anthropic, a U.S.-based AI startup and nonprofit organization, designed to connect LLMs and AI agents to various systems.

By offering an MCP server, GMO Sign will enable flexible integration and data exchange with a wide range of external services such as groupware, document management, and workflow systems that leverage various AI technologies.

◾️ Rapidly Responding to AI Utilization Needs with a Secure Remote MCP Server

There are two types of MCP server communication methods: local and remote.

A local MCP server runs on the user's PC terminal, allowing full customization. However, users must bear the burden of setting up, managing, and maintaining the environment. If not properly implemented and strictly managed, it poses significant security risks.

A remote MCP server, running on a cloud-based server, eliminates the need for users to run it on their own devices. This reduces many common security risks associated with local servers and removes the ongoing burden of environment setup and maintenance. However, it is crucial to use a reliable MCP server.

The remote MCP server provided by our company is secured and managed by GMO AI Connect, which has extensive experience in integrating diverse business systems such as generative AI, SaaS, and on-premises solutions.

Users can proceed with AI agent-driven business automation securely, without the complexity of setup or management, requiring only simple connection configurations.

◾️ Enabling Easy Operation of GMO Sign Directly Within Conversational AI Chat Interfaces

GMO Sign supports MCP apps, which allow interactive UI elements such as maps, graphs, and forms to be embedded directly within AI chat conversation interfaces.

By embedding GMO Sign's UI directly into the chat interface, users can operate the system more intuitively.

■ Use Cases (Examples)

[Demo Experience at the Legal & Compliance EXPO Booth]

The 'Legal & Compliance EXPO' is an exhibition within 'General Affairs, HR & Accounting Week,' targeting back-office professionals seeking comprehensive solutions for challenges ranging from DX to workplace improvements. It specifically caters to legal and intellectual property professionals.

At our booth, we will offer demo experiences of the MCP server using NDA (non-disclosure agreement) contracts as an example, accept early applications, and provide services and consultations to address a wide range of challenges related to signing, contracting, document management, and identity verification for enterprises and local governments. We welcome your visit.
