Connect Mirasapo Plus to ChatGPT
Query Mirasapo Plus directly from ChatGPT. Arlet links the two through one MCP connection and takes care of API keys.
This server connects your AI client to the Case Navi Data API of Mirasapo-plus (mirasapo-plus.go.jp), the SME support portal operated by the Japanese SME Agency. It contains curated case studies of small and medium-sized companies that used subsidies, grants, and public support programs.
Key features:
- Search case studies by keyword, prefecture, capital, and headcount of the company.
- Read a full case study: background, the challenge the company faced, what it did, the results, and which support programs were used.
- List the classification categories (industries, purposes such as sales expansion / IT adoption / financing / succession) to guide a search.
Combined with procurement and subsidy information, this is a strong starting point for advising SMEs: find companies with the same problem and see which support programs actually worked for them. The API is public and free, so no API key or registration is required.
