Overview

AI-generated overview

Remote MCP endpoint for independently verifying ZARONIA-linked coupon calculations on South African floating-rate notes and money-market paper.

What you can do
Verify is a remote MCP server from Zaronia Calculator that provides independent verification of ZARONIA coupon calculations for South African floating-rate notes and money-market paper, using a SARB-compounded index. The manifest lists no tools, so the exact operations are not documented here. It is reached over streamable HTTP at a hosted endpoint rather than run locally.
When to use it
Consider it when you need a second, independent check of ZARONIA-based coupon figures for South African floating-rate notes or money-market paper, for example to cross-check interest accrual or coupon amounts produced elsewhere.
Requirements
A client that supports the streamable HTTP transport and network access to the provider's remote endpoint. No packages, environment variables, headers, or authentication are declared in the manifest.
Before you install
The manifest declares no authentication, so requests to the remote endpoint are not shown to be authenticated or access-controlled; avoid sending confidential deal or portfolio data. No tools are listed, so what the server does with submitted figures cannot be confirmed from this input.

Installation

In SourceWeft

  1. Open Verify in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/za.co.zaroniacalculator.api%2Fverify/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
