AI Agent Building Support Service
Providing end-to-end support up to the building of AI agents
and a suitable platform, for accelerating
AI agent adoption by companies
Besides the simple implementation of agents, we comprehensively support the core of corporate AI agent strategy ranging from the building of databases and MCP servers optimized for the AI era to the utilization of first-party data for marketing by companies, as a multiagent platform to deliver Zero Data Sharing※. This is one of the key services of ONE-AIGENT, a package of AI agent-powered marketing support services offered by Hakuhodo DY ONE.
*What is Zero Data Sharing?
This is a ground-breaking concept of data coordination among companies advocated by Hakuhodo DY ONE, whereby AI agents intervene for securely linking only necessary information or the results of analyses without requiring the direct sharing of raw data. This technique is currently patent-pending. As of July 2025, we are building a system for trial with selected advertisers for the implementation of Zero Data Sharing.
Capability of AI agent building support service
Optimized design to make the best of AI agents
As an AI agent-oriented marketing provider, we offer optimized design and operation to make the best of AI agents. In a world where AI agents perform a wide variety of tasks, simply introducing relevant tools is not sufficient. Genuine operational optimization can only be achieved through integrated design of complicated elements. We offer integrated services ranging from the selection of AI agents to the design of prompts, workflows and coordination with various systems. We also provide one-stop support for the whole process of AI agent operation, including the cocreation of a decision-making process with the client, and the design of an AI learning loop to ensure ongoing improvements in performance.
Strategy upgrading with proprietary knowledge data of the Hakuhodo DY Group
Not limiting ourselves to the mere introduction of AI technology, we are leveraging the sei-katsu-sha data infrastructure of the Hakuhodo DY Group, one of the largest in Japan, and expert AI agents learning from our abundant knowledge data accumulated over the years in the course of advertising operation. We strengthen strategies for corporate advertising operation with AI technology in a data-driven way.
Service features
MCP server building support: Toward a platform suited to AI agents
We support the development of a Model Context Protocol (MCP) server to build a platform for in-depth, secure and rapid data retrieval by AI agents. We provide integrated support ranging from the development of the MCP-API interface, the design of access rights and security, and the consolidation of data connections to its deployment to the cloud/on-premise environment and operational maintenance.
Data platform building: Toward a data platform suited to AI agents/MCP
We help build a data platform optimized for “good data” required in the era of AI agents. We develop a clean data environment as the Gold Table (sole genuine data) to retain updated, precise and unique IDs and prevent hallucinations. We also clarify metadata including with the explanations, dates of update, frequency of updates, persons responsible for updates and confidentiality classifications of the data, and support tagging so that generative AI can leverage it precisely.
Sharing of the latest AI knowledge: Support for catching up with the latest trends and for optimization
We provide the latest AI knowledge on an ongoing basis, including on trends in fast-evolving AI technology, the latest cases of agent adoption, and best industry practices. Catching up with technological trends through regular communications, we keep the client’s AI agent operating in the optimal state. We accompany the client as a long-term partner in the implementation of AI agents, rather than simply supporting the building phase.
