Isir is a Model Context Protocol (MCP) server: Czech insolvency register (ISIR) — active/historical insolvency & bankruptcy by IČO or person. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
You can run Isir two ways: connect to the hosted endpoint at https://isir.cz-agents.dev/mcp with no local install, or run it on your own machine via the npm package @czagents/isir. The current release is v0.2.4, published under the MIT license, with source at martinhavel/cz-agents-mcp on GitHub.
You'll find Isir in the Development category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
