About honest-mcp
I maintain the honest-mcp family — 13 open-source MCP (Model Context Protocol) servers that let AI clients like Claude, Cursor, and Zed reach real services without a cloud middleman. Every server runs on your own machine and talks directly to the actual service API.
What I build
Polish tooling for JDG owners and accountants — nip-krs-mcp (Biała Lista + KRS), nbp-mcp (NBP FX rates), honest-vies-mcp (EU VAT check with audit-proof consultation number), mbank-parser-mcp (parses mBank CSV fully offline), pl-holidays-mcp (business-day math).
Polish public data — stat-gov-mcp (GUS BDL), nfz-mcp, imgw-mcp, gios-air-mcp.
Local Google alternatives — honest-gmail-mcp, honest-calendar-mcp, honest-drive-mcp. Your OAuth tokens stay on your machine.
Utility — rss-mcp.
Why sponsor
Every repo ships Dependabot, CodeQL, CI matrix on Python 3.10–3.13, secret scanning, and push protection. Your sponsorship funds continued maintenance: dependency bumps, new servers, security reviews, docs, and expanding the Polish tooling stack.
I'm a Warsaw-based developer running skanfirmy.pl with a day job at RTB House. Everything I publish is MIT licensed and free forever — sponsorship is what lets me keep the whole family in sync.
Also available for consulting on Polish tax integrations (KSeF, GUS/NFZ APIs, mBank data), MCP server design, and AI-assisted bookkeeping automation for JDGs and small teams. Reach out: firma@bartosza.pl
