Available tools 10

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

amount

amount_in_words

Spell a monetary amount in words, the way a cheque or an invoice requires — "Four Thousand and Fifty Naira and Seventy-Five Kobo Only". Supports NGN, USD, EUR and GBP with the correct major and minor unit names. It is the row that goes above the signature line on the invoices at https://zaleso.com/invoice

base64

base64_convert

Encode text to Base64, or decode Base64 back to text. UTF-8 throughout, so accented text, emoji, Arabic, Devanagari and CJK survive the round trip — the naive btoa/atob version does not. Interactive version: https://zaleso.com/base64

generate

qr_generate

Generate a QR code as an SVG image from text or a URL. The code encodes the value directly — no tracking redirect, so it works forever. Interactive version: https://zaleso.com/qr

gross

ng_gross_for_take_home

Work backwards from a target take-home to the gross salary that produces it, under the Nigeria Tax Act 2025 (2026 tax year). This is the question employers and contractors actually ask — "what must I pay for them to clear ₦500,000 a month" — and it cannot be answered by applying a rate, because PAYE is banded. Returns the required gross with the full band-by-band working and the statutory source. Informational only — verify with the tax authority. Interactive version: https://zaleso.com/ng/net-salary

invoice

invoice_totals

Compute invoice totals from line items: per-line totals, subtotal, an optional discount, optional tax (the verified Nigeria VAT preset or any rate you name), a deposit already paid, and the balance due. Country-agnostic. The interactive version also produces the PDF: https://zaleso.com/invoice

json

json_format

Format (pretty-print) or minify JSON. Invalid input returns the line and column of the error. Interactive version: https://zaleso.com/json

password

password_generate

Generate a cryptographically secure random password (crypto.getRandomValues with rejection sampling — no modulo bias). Returns the password and its entropy. Interactive version: https://zaleso.com/password

paye

ng_paye_calculate

Calculate Nigeria PAYE income tax and net (take-home) salary under the Nigeria Tax Act 2025, effective for the 2026 tax year. Returns monthly take-home, monthly PAYE, the effective rate, and the full band-by-band working, with the statutory source and verification date. Handles pension (8%), NHF (2.5%, voluntary), rent relief (20% of rent, capped at ₦500,000), and the minimum-wage exemption. Figures are informational — verify with the tax authority. Interactive version: https://zaleso.com/ng/paye

usd

usd_ngn_convert

Convert between Nigerian naira and US dollars, pounds, euros and other currencies at the Central Bank of Nigeria's official rate — the latest, or the rate that applied on a past date. The dollar uses the NFEM rate (the volume-weighted average CBN publishes); other currencies use CBN's selling rate. Never a parallel-market figure. Returns the converted amount with the rate, the trading date it applies to, and the CBN source. Interactive version: https://zaleso.com/ng/fx

vat

ng_vat_calculate

Add Nigerian VAT to a net amount, or extract the VAT already contained in a VAT-inclusive amount. Uses the verified statutory rate from the data layer and returns it with its source and effective date — never an assumed rate. Informational only — verify with the tax authority. Interactive version: https://zaleso.com/invoice

Zaleso — questions

Answers built from our own checks of this server.

What can Zaleso do?

It exposes 10 tools, read directly from the server on our last check. Among them: amount_in_words, base64_convert, invoice_totals, json_format, ng_gross_for_take_home, ng_paye_calculate and 4 more. 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 Zaleso working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 128 ms. The bar chart above shows every period we have measured.

How do I connect Zaleso?

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 Zaleso need an API key?

No. Zaleso completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Zaleso?

It answers our handshake in 128 ms on average, which is faster than 87% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
