Overview

AI-generated overview

Zaleso is a remote MCP server of small utility tools: Nigerian PAYE and VAT calculations, CBN currency rates, invoice totals, QR codes, passwords, JSON and Base

What you can do
Calculate Nigerian PAYE tax and net salary, work back from a target take-home to gross, and add or extract Nigerian VAT with the statutory rate and source returned. Convert between the naira and USD, GBP, EUR and other currencies at Central Bank of Nigeria rates, latest or historical. Compute invoice totals from line items with discount, tax, deposit and balance due, and spell monetary amounts in words for NGN, USD, EUR and GBP. Generate QR codes as SVG and cryptographically secure random passwords with entropy. Format or minify JSON and encode or decode Base64 with full UTF-8 support.
When to use it
Useful when an assistant needs quick, sourced Nigerian payroll and VAT figures, CBN exchange rates, or everyday formatting and encoding chores such as invoice math, amount-in-words, QR codes, passwords, JSON and Base64, without installing anything locally.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared. Network access to the endpoint is required.
Before you install
Tax and exchange-rate results are informational and should be verified with the tax authority or CBN. The password tool returns generated secrets through the conversation, so treat them as exposed. All tools are read-only calculations; nothing is written or sent to third parties beyond the endpoint itself.

Installation

In SourceWeft

  1. Open Zaleso 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/com.zaleso%2Ftools/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

ParameterstextrequirederrorCorrection

password_generate

Generate a strong password

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

ParameterslengthsymbolsexcludeAmbiguous

ng_paye_calculate

Nigeria PAYE calculator (2026)

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

ParametersperiodincludeNhfgrossIncomerequiredincludePensionrentPaidAnnualotherDeductionsAnnual

json_format

Format or minify JSON

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

Parametersjsonrequiredmodeindent

ng_gross_for_take_home

Nigeria gross-up (salary for a target 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

ParametersperiodtakeHomerequiredincludeNhfincludePensionrentPaidAnnual

ng_vat_calculate

Nigeria VAT (add or extract)

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

Parametersmodeyearamountrequired

invoice_totals

Invoice totals (any currency)

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

ParametersvatlinesrequireddeposittaxRatecurrencytaxLabeldiscountAmountdiscountPercent

amount_in_words

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

Parametersamountrequiredcurrency

base64_convert

Base64 encode or decode

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

Parametersmodetextrequired

usd_ngn_convert

Convert naira at the official CBN rate

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
