japanfinance-agent 0.1.8

Compound MCP agent combining Japan finance data sources — EDINET, TDNET, e-Stat, stock prices

japanfinance-agent

Compound MCP agent that combines Japan finance data sources into high-value analysis tools. Instead of calling each source individually, get comprehensive company analysis, macro snapshots, and earnings monitoring in a single request.

Part of the Japan Finance Data Stack: edinet-mcp (securities filings) | tdnet-disclosure-mcp (timely disclosures) | estat-mcp (government statistics) | stockprice-mcp (stock prices)

Why?

Each Japan finance MCP provides focused data from one source. But real analysis needs multiple sources combined:

What you want	Without japanfinance-agent	With japanfinance-agent
Company analysis	3 sequential MCP calls (EDINET → TDNET → stock)	analyze 7203
Macro overview	e-Stat search + result aggregation	macro -k GDP
