Mercury MCP MCP integration
Reports account balances and cards, opens transactions with their attachments, pulls invoices and customers, and covers treasury and pending approvals.
30actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Getaccounts
Lyro retrieves a paginated list of all accounts associated with the authenticated organization. Finance teams review their full account portfolio instantly instead of logging in to Mercury separately.
Getaccountstatements
Lyro fetches monthly statements for a specific account to show transaction history and balances. Customers get account summaries immediately when Lyro pulls their statements during conversation.
Getorganization
Lyro pulls organization details including legal business name and DBAs for customer verification. Support staff confirm company identity quickly without digging through corporate documents.
How businesses use Mercury MCP + Lyro
Each card is one request a support team gets, and the Mercury MCP actions Lyro runs to close it.
Report on balances and the cards behind them
Lyro pages through the organisation's accounts, opens a specific one by ID, and lists every debit and credit card attached to it so a spend question resolves to the card that made it.
Get AccountsGet AccountGet Account CardsTrack down one transaction and its paperwork
Lyro lists transactions on an account, opens one by ID with its full detail including check images and related metadata, and fetches the download URL for the attachment filed against it.
List TransactionsGet Transaction By IDGet AttachmentReconcile an invoice against the customer who owes it
Lyro pages the invoice list, opens the specific invoice with its attachments, and pulls the customer record behind it so a receivables question is answered in one pass.
List InvoicesGet InvoiceGet CustomerCover treasury and payments waiting on approval
Lyro lists the treasury accounts on the organisation, reads the transactions and statements against one of them, and reports which send-money requests are still sitting in approval.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Mercury MCP actions it has and picks the ones a request needs.
Connect Mercury MCP
Authorize the Mercury MCP account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Mercury MCP actions that close it and chains as many as the request needs.
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

FAQ
Everything else about Mercury MCP
Setup, permissions, and the limits of what Lyro can do inside Mercury MCP.
No, and by design. Mercury MCP is a read-only server, so every action in this toolkit retrieves data and none of them initiate a payment. List Send Money Approval Requests reports which transfers are pending approval and their status, but approving or sending one stays inside Mercury with a human.
