japanfinance-agent

Status: Maintenance mode — This project is stable and functional but not actively developed. Issues and PRs are welcome.

CI PyPI version Python 3.10+ License: Apache-2.0

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:

Architecture

japanfinance-agent
├── analyze_company(code)     → EDINET + TDNET + stock (parallel)
├── macro_snapshot(keyword)   → e-Stat government statistics
├── earnings_monitor(codes[]) → TDNET × N companies (parallel)
└── check_data_sources()      → connectivity status

Adapters (graceful degradation — missing packages return empty results):

├── tdnet-mcp     → Timely disclosures (earnings, dividends, buybacks)
├── estat-mcp     → Government statistics (GDP, CPI, employment)
