Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verify
verify_frn_coupon
PAID ($0.25). Independently recompute and verify a listed South African ZARONIA FRN coupon (SARB §2.2.3 compounded-index formula). Returns the coupon to 4dp, full audit workings (observation dates, index values, formula), and a match/mismatch verdict at 0.05bp tolerance when expected_coupon_pct is given. Pass api_key if you have one; otherwise the response explains how to pay via x402.
verify_otc_coupon
PAID ($0.10). Independently recompute and verify an OTC money-market ZARONIA coupon (1-bday lookback, Act/365, half-up 4dp). Returns coupon, workings and a verdict at 0.05bp tolerance when expected_coupon_pct is given. Pass api_key if you have one; otherwise the response explains how to pay via x402.
conventions
get_conventions
FREE. The exact calculation conventions of both engines (listed FRN: SARB §2.2.3 compounded index, 5-bday lookback, Modified Following; OTC: 1-bday lookback, Act/365, half-up 4dp), the verification tolerance, and the index source. Call this first.
latest
get_latest_index
FREE. The latest published SARB Compounded ZARONIA Index point — date and 12dp value. Use it to confirm data freshness before verifying.

Verify — questions

Answers built from our own checks of this server.

What can Verify do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_conventions, get_latest_index, verify_frn_coupon, verify_otc_coupon. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Verify working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 805 ms. The bar chart above shows every period we have measured.
The registry lists Verify as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Verify?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Verify need an API key?
No. Verify completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
