Position vs. similar projects

EDINET DB is the production-grade, OAuth-authenticated, multi-tenant SaaS remote MCP for Japanese financial filings. Other Japan-specific MCP servers (e.g., bug-tracker for individual contributors) are local stdio implementations requiring users to obtain their own API keys and run a local process. The 5,000+ authenticated user base reflects production usage since 2026-03-01.
