Mercury MCP server
Remote endpoint mcp.mercury.com/mcp. Checked September 2026.
Balances, transactions with merchant and category detail, monthly statements, cards, payment recipients, and invoice and customer records are what Mercury's hosted server returns for a business's checking, savings, and treasury accounts. It is read-only and cannot move money.

Other ways to reach Mercury data
One MCP server per tool still can't answer a cross-channel question.
Each server brings its own sign-in, its own definition of revenue, and data your assistant can't join to the rest.
SourceMedium connects 63 commerce and marketing sources, keeps one set of maintained definitions, and gives ChatGPT, Claude, and other assistants a single connection to all of it. Mercury is not a SourceMedium source today.
