Openfinance Br MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 69 installs a week from pypi. Last commit 17 Jul 2026.
Secure Open Finance Brasil MCP server with typed tools and a credential-free mock mode
Today is the operative word: we check Openfinance Br 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.
