Mercury

Mercury is a financial platform for startups and growing businesses, and its MCP server gives Notion AI access to your financial data, transactions, and expense categories. Ask Notion AI to review recent transactions, update a transaction's note or category, or create a payment request to an existing recipient. Payment and transfer requests still need approval in Mercury before money moves.

With Notion Agent

1. Select Get connection on this page.
2. Sign in with your Mercury account and approve access.
3. Ask Notion AI to use Mercury by name.

Try asking:

• "Show my Mercury transactions from last week over $1,000"
• "Change the category on this Mercury transaction to Software"
• "Check the status of my pending payment requests in Mercury"

With Custom Agents

1. Open your agent's Settings → Tools & Access and select Add connection.
2. Choose Mercury, sign in, and pick the tools the agent can use.
3. Select Connect. Each agent has its own connection.

MCP connections are available on Business and Enterprise plans, on web and desktop.
