Loan Payment Calculation for AI AgentsLoan Payment Calculation for AI Agents

OnlineCredit Usage:1 per callTool:LoanPaymentCalculationforAIAgents

The tool

Give enterprise agents accurate loan math through the same data layer, returning monthly payment and total interest per request.

Once your client is connected to the VerveContext MCP server, this appears in its tool list as LoanPaymentCalculationforAIAgents. It is read-only and open-world: it fetches, it never mutates anything on your side, so most clients will call it without asking you to confirm.

Tool call
{
  "name": "LoanPaymentCalculationforAIAgents",
  "arguments": {
    "loanAmount": "20000",
    "interestRate": "5.5",
    "loanTerm": "5"
  }
}

What that looks like in a conversation

You don't name the tool — the model picks it. Asking about 20000 in the terms this source covers is enough for it to reach for LoanPaymentCalculationforAIAgents on its own.

Connecting

One server URL covers every source in the catalog, including this one. Authorization is OAuth — the client opens a browser once and there is no key to paste into a config file.

Client config
{
  "mcpServers": {
    "vervecontext": {
      "url": "https://api.vervecontext.com/v1/mcp"
    }
  }
}
Endpoint
https://api.vervecontext.com/v1/mcp

Per-client setup — Claude Desktop, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made.

ArgumentTypeExampleDescription
loanAmountRequirednumber20000The loan amount
interestRateRequirednumber5.5The interest rate (percentage)
loanTermRequiredinteger5The loan term in years
downpaymentnumber5000Amount paid up front, subtracted from the loan amount before interest is applied

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client can read fields without parsing prose. status is "ok" on success and error is null; a null field means the value wasn't available for that input, not that the call failed.

Fields

Fields marked Premium need a paid plan. On a plan without them the key is absent rather than wrong, so a model never reasons over a substituted value.

Why ground on it

A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong. This source returns the current value with a shape you can check, which is the difference between an answer you can cite and one you have to hedge.

Point an evaluation at monthly_payment: it is the field most worth pinning a claim to, and it is either present and current or absent — never plausibly invented.

Failure modes

Errors come back as tool errors with a sentence the model can act on, not a bare status code.

StatusWhat it means
400 / 422The arguments didn't validate. The message names the offending one.
401The OAuth session is invalid or expired — reconnect the server.
403Out of credits. Not a bad key — the month's allowance is spent.
404This source isn't part of VerveContext. Check the catalog.
429Brief rate limit. Retrying after a moment succeeds.

Frequently asked questions

Do I have to tell the agent to use LoanPaymentCalculationforAIAgents?

No. The tool's name and description are in the model's context once the server is connected, so it selects the tool when the question calls for it. Naming it explicitly works too and is useful when you want to force the call.

Does connecting the server expose every tool at once?

Yes — one connection lists the whole VerveContext catalog. Clients with a tool budget can usually filter the list; the credit cost is per call, so an unused tool costs nothing.

What does a call cost?

1 credit each time the tool actually runs. A model that reasons about the tool without calling it costs nothing.

Is there a REST version of this?

Yes — the same source is available as a plain HTTPS endpoint on APIVerve, linked above. Same data, same credits, same account.
