Connects Claude to the full DaData.ru API with 31 tools covering address validation, company lookups, geocoding, and data standardization for Russian entities. Goes beyond DaData's official 4-tool MCP by exposing OKVED lookups, brand searches, self-employed verification, passport checks against MVD registries, and 12 reference directories. Most tools are free within DaData's 10,000 daily request limit. The clean_* operations cost 0.20 rubles per call and require a secret key. Runs locally via npx with stdio transport. Part of a 47-server Russian API MCP series. Useful when building tools that need to validate Russian addresses, verify counterparties by INN, standardize phone numbers and emails, or pull company financials and affiliations.
