OpenFIGI MCP server wrapping the free OpenFIGI API v3 (api.openfigi.com — no authentication required for basic use; optional OPENFIGI_API_KEY env var for higher rate limits). 6 tools: map_isin (ISIN → FIGI with exchange, security type, currency), map_cusip (CUSIP → FIGI), map_sedol (SEDOL → FIGI), lookup_by_ticker (ticker + optional exchange code or asset class → matching instruments), search_by_figi (FIGI → full instrument details), batch_map (map up to 10 identifiers in one call — mix of ISIN, CUSIP, ticker, SEDOL). Supports 50+ exchanges (exchCode: US, LN, GY, TT, HK, etc). Essential for instrument master data, cross-system identifier reconciliation, and FIGI-based instrument tracking.
