increase_create_achor sweep high-value overnightincrease_create_wiresecurely. - Simulation Environment — Use Sandbox arrays to trigger simulated money hits
increase_simulate_inbound_achchecking if an external agent script validates receiving deposits before going to production.
How it works
- In the Increase dashboard, decide if you're in Development (Sandbox) mode or Live (Production) mode.
- Obtain an API Key (
sk_testorsk_prod). - Plug the key directly into Vinkius to sync the core network natively with agent logic.

Frequently asked questions
Can I test money flows safely without losing real funds?
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.
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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
