MCP Server for YNAB runs on your own machine — the client starts it, so there is no endpoint to ping. 181 installs a week from pypi. Last commit 4 Oct 2026.
Connect your AI assistant to YNAB. Read-only by default, with reversible opt-in writes.
Today is the operative word: we check MCP Server for YNAB every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start:
YNAB_API_KEY (YNAB personal access token from app.ynab.com/settings/developer.), YNAB_PLAN_ID (Default plan (budget) id, so tools do not need it passed on every call.), YNAB_ALLOW_WRITES (Set to 1 to register the write tools. Unset means read-only, and the write tools are absent from tools/list entirely.).
The author declared them in the registry entry; get the values from the project itself.
