Edinet Mcp

Connects Claude to Japan's EDINET financial disclosure system with automatic XBRL normalization across J-GAAP, IFRS, and US-GAAP. Nine tools let you search 5,000+ listed companies, pull balance sheets and income statements by period, calculate ROE and profit margins, screen up to 20 companies at once, and diff statements across fiscal years with change amounts. The Python client handles rate limiting and caching, and statements come back as Polars DataFrames with consistent labels like 売上高 regardless of accounting standard. Requires a free EDINET API key. Reach for this when analyzing Japanese corporate financials or building comps tables without wrestling with heterogeneous XBRL taxonomies.
