Mercury Multiorg MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 86 installs a week from pypi. Last commit 15 Sep 2026.
Unofficial read-only MCP server exposing several Mercury banking organizations to one AI session.
Today is the operative word: we check Mercury Multiorg MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Optional settings from the registry entry, left out of the block above:

Ignored when --entities is passed), MERCURY_API_BASE (Mercury API host. Allowed without extra flags: https://api.mercury.com, https://api-sandbox.mercury.com (with sandbox tokens), or a loopback mock), MERCURY_ALLOW_DOCUMENTS (Set to true to register get_statement_pdf and get_invoice_pdf, which return statement and invoice PDFs unredacted.
