DaData MCP: Documentation

Connection

Remote: https://mcp.dadata.ru/mcp (Streamable HTTP). Auth: an Authorization: Bearer API_KEY:SECRET_KEY header — keys are issued right after free signup at dadata.ru. Clients without native Streamable HTTP support (e.g. Claude Desktop) go through the supergateway shim in their mcpServers config. Compatible with Claude, the OpenAI API, LM Studio and other MCP/agent platforms.

Capabilities

Three tools:

• Company by TIN/OGRN — input a TIN or OGRN, get back details, status, CEO and address from the Unified State Register.
• Email/domain owner — input a domain or corporate email, get back the owning company's details.
• Address — input an address in any form, get back a standardized address and geo-coordinates.

Agent flow

"Check the counterparty with TIN 7707083893", "figure out what these companies do and pick out the IT ones", "here are webinar attendees' emails — which companies do they work at?", "standardize this address list and add coordinates".

Pricing

• Email/domain owner — 7 RUB per result, first 50 companies free (top up your balance to enable paid requests).
• Address (standardization + geocoding) — 0.20 RUB per query, first 100 addresses free.
