The Financial Dashboard Click-Through

Today, getting a full picture of your company's cash requires logging into the Mercury dashboard, clicking between 'Balances,' then 'Transactions,' and finally opening separate pages to check account numbers. You spend five minutes just navigating tabs and applying filters before you even see the data.

With this MCP, you tell your agent what financial view you need. It handles the multi-step process behind the scenes, pulling specific records—like running list_transactions or fetching get_treasury_balance—and handing you a clean, summarized answer in seconds.

Getting Payment Data with Mercury MCP

Manual payment setup involves multiple steps: finding the vendor's details, checking if they are saved as a recipient, and then manually entering their routing numbers into a separate system. This process is slow and prone to human error.

Now, your agent takes over. It checks list_recipients for existing payees, or uses create_recipient if you need to add someone new. You just tell it the vendor name, and it executes the full payment setup lifecycle.

What Mercury MCP does for your AI

Connect your company's finances conversationally. This MCP lets your AI agent handle tasks that used to require logging into the Mercury web portal. You can ask for an instant snapshot of all active account balances or pull transaction records, filtering them by dates or specific amounts right from your development environment.

Need to make a payment? Your agent manages everything from listing existing recipients to creating new ones for ACH and wire transfers. Because this integration is hosted on the Vinkius catalog, you connect once using your preferred AI client—whether that's Cursor, Claude, or Windsurf—and gain access to banking data across multiple systems.

You don't just get data; you execute operations. You can retrieve key account details like routing numbers and also pull full bank statements for auditing purposes.

Frequently asked questions about Mercury MCP

Can Mercury MCP only read data, or can I send money? +

You can do both. This MCP allows your agent to list payments using list_payments, but it also lets you execute payment actions by listing and creating recipients.

Which tool should I use for a general balance check with Mercury MCP? +

Use get_treasury_balance or list_accounts. These tools give you an immediate, comprehensive overview of the total cash available across all your linked accounts.

How do I find out what transactions occurred last quarter using Mercury MCP? +

You use list_transactions and provide date filters in your prompt. The agent pulls only those records, saving you from scrolling through pages of data.

Is there a way to get account metadata besides the balance via Mercury MCP? +

Yes, the get_account tool specifically retrieves crucial details like routing numbers and general bank account metadata that your code might need.

Do I have to manually update my API key every time I use Mercury MCP? +

No. Once you subscribe via Vinkius, the connection is managed securely through an established token process, allowing continuous data access without constant manual intervention.

How do I get my Mercury API token? +

Log in to your Mercury account at app.mercury.com. Go to Settings → API Tokens and click Create Token. Choose the token type (Read Only for balance checks, or Read and Write for managing recipients). Copy the token immediately — it will only be shown once. Paste it into the configuration field below, and you're ready. No code, no SDK, no webhooks.

Can my AI agent check my startup's runway instantly during a board meeting? +

Absolutely. Just ask your AI agent 'What's my current balance across all Mercury accounts?' and it returns real-time balances for every account — checking, savings, and treasury — in seconds. No tab-switching, no logging in, no waiting for the dashboard to load.

What if I need to review recent transactions for month-end close? +

Ask your AI agent to pull transactions from any date range. It retrieves each transaction with amount, counterparty, status, and date — perfect for reconciliation. You can filter by account, ask for Wire vs ACH breakdowns, or request only transactions above a specific threshold, all without exporting CSVs.

Is this suitable for companies with multiple Mercury accounts? +

Yes. The integration retrieves data across all accounts linked to your API token — operating accounts, savings accounts, and treasury balances. Perfect for venture-backed startups managing multiple entities, holding companies, or finance teams tracking cash positions across subsidiaries.
