Details
From the project READMEKontragentPro MCP server
Look up Russian companies by INN (tax ID) directly from Claude Desktop, Cursor and any MCP-compatible client. A thin wrapper over the public KontragentPro API v2, serving data from Russian open registries: EGRUL (company registry), Federal Tax Service financial statements, bankruptcy register, state inspections, trademarks, sanctions and foreign-agent lists.
Works without an API key — anonymous free tier is enabled by default, so you can try it in under a minute.

Data sources
All data comes from official Russian open registries — EGRUL/EGRIP, the Federal Tax Service (financial statements, tax regimes), the federal bankruptcy register, the Prosecutor General's inspection registry, Rospatent trademarks, and public sanctions lists. Each block on a company card carries its source and retrieval date.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
