Before you connect

Questions about Increase.

The practical details behind the request, access and result.

What is the Increase MCP?

It connects your AI agent to a real US commercial bank. This lets your agent perform actions like creating accounts, sending wires, and issuing cards programmatically.

Can I use this for my fintech startup?

Yes, this is built for platform builders who need to offer banking services like sub-ledgers and debit cards to their customers.

Does this support same-day wires?

Yes, you can use the wire capability to send high-value transfers that need to arrive the same day.

How do I test my deposit logic?

You can use the sandbox capabilities to simulate inbound ACH or wire transfers. This lets you verify your app's logic without moving real money.

Can I see my transaction history?

Yes, your agent can pull a full list of booked transactions to help you audit your financial history.

Is this for international banking?

No, this Connector is specifically for US commercial banking and domestic payment rails like ACH and wires.

Can I test money flows safely without losing real funds?

Absolutely. Increase has a top-tier sandbox environment. In your Connector settings, pass a Sandbox API Key (starting with sk_test_) and optionally set the environment to 'sandbox'. We even implemented literal capability overrides like increase_simulate_inbound_ach which are intentionally restricted exclusively to simulating inbound events on your test environment.

Does adding a new account via the Agent require paperwork?

No! Assuming your global LLC has already passed initial onboarding and your Entity object handles compliance, any subsequent programmatic calls to increase_create_account yield a fully compliant sub-ledger and associated numbers instantaneously contextually within the UI chat responses.

What is the difference between ACH and Wire transfer arrays here?

ACH acts through clearing houses taking normally 1-3 business days suited perfectly for non-urgent vendor mass payouts (create_ach). Wire transfers (create_wire) tie directly to Fedwire routing logic hitting banks internally within minutes - often bearing a slight static fee. Dictate which the bot should invoke based on liquidity needs.

How can I trace a specific payment?

We've added increase_list_transactions to handle historical booked transfers strictly by ID limits, exposing whether money cleared Fed limits safely.
