Wfirma MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 20 installs a week from npm. Last commit 27 Aug 2026.
Unofficial read-only MCP server for the wFirma API v2: invoices, contractors, expenses, payments.
Today is the operative word: we check Wfirma MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

The author declared them in the registry entry; get the values from the project itself.
