Overview

AI-generated overview

Remote MCP server for Polish company data from the KRS register: profiles, connections, financials, state aid and public contracts.

What you can do
  • Search Polish companies by name, NIP, REGON or KRS number and get the KRS number needed for other tools
  • Read a company's registry profile, including legal form, status, address, share capital, PKD codes and, with full=true, boards and risk states
  • List current and historical people and entities connected to a company, and the companies they are linked to
  • Retrieve a timeline of registry changes from KRS and MSiG, with optional date range and paging
  • Get multi-year financial summaries or a single year's full statement with balance sheet, P&L and cash flow where available
  • Look up state aid received and public contracts, plus the balance and usage of the API key
When to use it
Useful when an assistant needs verified facts about Polish companies: due diligence, checking who runs or owns a company, comparing financial results, or seeing whether a firm received state aid or won public tenders.
Requirements
Remote Streamable HTTP endpoint; no installation. Requires a tropia.pl API key sent as an Authorization bearer header (or as a URL parameter for clients that cannot send headers). A Docker stdio image is offered for local-only clients, configured with the TROPIA_API_KEY environment variable. Paid keys are prepaid.
Before you install
Calls are billed per request from a prepaid balance (0.03–0.20 PLN each), so repeated or broad queries spend money; check the balance with the free account tool. The API key is a secret and should not be shared. Data covers public Polish registers and includes personal data about board members and shareholders; the server does not expose PESEL numbers or beneficial owner data.

Installation

In SourceWeft

  1. Open tropia.pl: Polish companies (KRS) in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/pl.tropia%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

tropia.pl MCP server and API: Polish company data from KRS

Remote Model Context Protocol server and REST API by tropia.pl, the Polish company intelligence service built on the National Court Register (KRS).

  • 1.2 million entities from KRS (913,000 active): companies, foundations, associations, cooperatives
  • Current and historical connections: board members, supervisory boards, shareholders and proxies with dates from/to: who ran or owned a company in the past, not only today
  • Registry change history from KRS and the Court and Economic Monitor (MSiG)
  • Financial statements of 630,000 companies from the eKRS repository: revenue, profit, assets, equity; full balance sheet and P&L line by line where available
