Softwiro Excel templates and calculators

Softwiro MCP

An MCP server that lets an AI assistant calculate inside 67 free Arabic Excel templates and run 23 quick calculators (VAT, BMI, due date, gold zakat and more), instead of guessing the numbers. Results come from the templates' own formulas and the calculators' own code. Stateless, no API key, nothing stored.

• Hosted endpoint (free, no key): https://softwiro.com/api/mcp (Streamable HTTP)
• Overview, examples, terms and privacy: https://softwiro.com/mcp · Arabic: https://softwiro.com/ar/mcp
• Step-by-step guide with a worked example: https://softwiro.com/blog/mcp-excel-templates-ai-agent-guide.html
• Official MCP Registry name: com.softwiro/templates

Ask your assistant to use it explicitly ("use the softwiro MCP and do not calculate yourself"). Without that, an assistant may calculate in its head and never call the tool.

Connect

These steps follow each app's own documentation; menus can differ by plan and version.

Claude Code

claude mcp add --transport http softwiro https://softwiro.com/api/mcp

Claude (web / desktop): Customize → Connectors → + Add → Add custom connector, name softwiro, URL above.

ChatGPT: Plugins → + → Add custom MCP server, name softwiro, URL above, authentication: *No authentication*. Custom MCP servers may need a plan or workspace setting that allows them.

Cursor (.cursor/mcp.json):

{ "mcpServers": { "softwiro": { "url": "https://softwiro.com/api/mcp" } } }

Check it from a terminal:

curl -s https://softwiro.com/api/mcp \

-H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Tools

All six are read-only and idempotent (templates that use TODAY() follow the server's date).

Calculators

13 from Softwiro: VAT, BMI, calories, due date, ovulation, break-even, garment costing, fabric requirements, piece-rate pay, pharmacy margin, reorder point, no-show cost, study timetable.

10 gold calculators from Qintar: zakat on gold, silver and cash, nisab, making charge, bar and pound prices, fair-price check, sell-now, unit conversion, budget, gold vs certificates vs dollar, swapping old gold for new. They fetch live prices from qintar.app and return an error if prices are unavailable. Results are indicative: the zakat and gold calculators are not a fatwa, and the health calculators are not medical advice.

Example

Use the softwiro MCP (run_calculator with vat-calculator) and do not calculate anything yourself.

Egypt, add VAT to two items of 1,000 each and one item of 250.

Returns net 2,250, tax 315, total 2,565 (VAT 14%).

Run it yourself

Node 18+.

npm install

npm start # http://127.0.0.1:3000/api/mcp npm test # offline smoke test

Environment variables: PORT, HOST, TRUST_PROXY (set to 1 behind a reverse proxy so rate limits see the real client address), USAGE_FILE (JSON file for aggregate counters; omit to keep them in memory), SITE_BASE (base URL used in catalog links, default https://softwiro.com).

As a library

const express = require('express');

const { configure, mount } = require('./src/index'); configure({ dataDir: './data' }); // also: templatesDir, schemasDir, siteBase, usageFile, catalog() const app = express(); mount(app, express);

Layout

src/index.js          HTTP handlers, MCP JSON-RPC, limits, aggregate usage counters

src/worker.js one calculation in an isolated worker thread (timeout kills it) src/engine.js the formula engine (fast-formula-parser with Excel-compatible tweaks) src/tools-softwiro.js the 13 Softwiro calculators src/tools-gold.js the 10 Qintar gold calculators data/catalog.json template catalog data/templates/ the .xlsx files data/schemas/ one JSON schema per template data/tool-text.json Arabic page text of the calculators

Limits

Request body 200 KB, at most 500 rows and 500 cells, 30 calculations and 120 reads per minute per client, 15 seconds per calculation, 2 calculations at once.

Privacy

Request content is not stored or logged by this server. It keeps aggregate daily counters only (calls per tool, template or calculator, errors, and the connecting app's name such as claude-code): no IP addresses and no request bodies. The hosted service sits behind the softwiro.com web server, which keeps ordinary access logs for a short period (see https://softwiro.com/privacy). The zakat calculator sends the amounts you enter to Qintar's calculator service.

Tests

npm test is an offline smoke test. test/parity/gold.test.mjs compares the gold calculators with the live Qintar pages in a headless browser (dev-only: needs playwright-core and a Chromium, or CHROME_PATH).

License

Code: MIT, see LICENSE. The files in data/templates/ are the same free Excel templates published at https://softwiro.com/templates: use, edit and share them freely.

Softwiro MCP (بالعربي)

خادم MCP يخلّي مساعد الذكاء الاصطناعي يحسب داخل 67 قالب إكسل عربي مجاني ويشغّل 23 حاسبة (ضريبة القيمة المضافة، كتلة الجسم، موعد الولادة، زكاة الذهب وغيرها) بدل ما يخمّن الأرقام. النتائج من معادلات القوالب نفسها ومن كود الحاسبات. بلا مفتاح ولا حساب، ولا يخزّن شيئًا.

• ابدأ طلبك بـ «استخدم الـ MCP بتاع softwiro وماتحسبش بنفسك» عشان المساعد ينادي الأداة بدل ما يحسب في دماغه.

الأدوات الست: list_templates (بحث في القوالب)، get_schema (هيكل القالب)، calculate (الحساب في قالب)، get_download (روابط التحميل)، list_calculators وrun_calculator (الحاسبات). النتائج استرشادية: حاسبات الزكاة والذهب ليست فتوى، والحاسبات الصحية ليست نصيحة طبية.

التشغيل محليًا: npm install ثم npm start.
