More Details Connect to Claude

The Increase MCP Server connects AI to a physical, fully compliant commercial US bank built explicitly top-down for programmatic transactions.

What you can do

  • Endless Provisioning — Instantly generate new live bank accounts increase_create_account acting as sub-ledgers, enabling separate balances.
  • Open Payment Rails — Need to inject funds into a supplier directly using native American payment streams? Use increase_create_ach or sweep high-value overnight increase_create_wire securely.
  • Simulation Environment — Use Sandbox arrays to trigger simulated money hits increase_simulate_inbound_ach checking if an external agent script validates receiving deposits before going to production.

How it works

  1. In the Increase dashboard, decide if you're in Development (Sandbox) mode or Live (Production) mode.
  2. Obtain an API Key (sk_test or sk_prod).
  3. Plug the key directly into Vinkius to sync the core network natively with agent logic.

Who is this for?

  • Platform Builders (BaaS) — Create internal software that orchestrates money mapping transparently.
  • Advanced Corporate Ops — Fire up temporary transaction routing numbers to accept wires.

See how to talk to your AI agent using Increase.

Use our main test routing sandbox mechanism to simulate inbound an external payload of $1000 into Account ID 'acc_1234'.

Simulation dispatched! Expected parameters were simulated into the core routing infrastructure successfully. The endpoint responded and acknowledged $1,000 artificial liquidity injection into your routing destination target. Validate your app webhooks now.

Audit our entire open accounts layout right now.

Found exactly 4 Demand Deposit accounts running 'opened' conditions. They map respectively under entity groups 'Operational', 'Cloud Subscriptions', 'Holding', and 'Local Dev'. Current aggregate counts reflect stability.

Spin up a new fresh physical corporate banking account dedicated uniquely to 'Server Spends'. Send the Routing number to me.

Success chain completed in sequence. First, entity 'Server Spends' received a booked ID structure constraint within banking logic. Secondly, the routing generator hooked an incoming ABA/Account array assigned completely to this context. Account numbers are currently available.

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