Parsi MCP

parsi-mcp

English | فارسی

An MCP server that gives AI agents (Claude, Cursor, VS Code Copilot and others) reliable Persian and Iran-specific tools. It runs fully offline, with no API keys: Jalali dates, Iranian validators, Persian text handling, grouped price inputs with Persian words, and an RTL frontend toolkit.

56 tools. See the full list in TOOLS.md.

Install

Requires Node.js 18+. The npx commands below work once the package is published to npm; until then use the local build.

Claude Code

claude mcp add parsi -- npx -y parsi-mcp

Or install the plugin, which adds the MCP server and the persian-rtl-frontend skill:

claude plugin marketplace add amirjld/parsi-mcp
claude plugin install parsi@parsi-mcp

Cursor (~/.cursor/mcp.json or .cursor/mcp.json in a project)

{ "mcpServers": { "parsi": { "command": "npx", "args": ["-y", "parsi-mcp"] } } }

Claude Desktop (claude_desktop_config.json: %APPDATA%\Claude\ on Windows, ~/Library/Application Support/Claude/ on macOS)

{ "mcpServers": { "parsi": { "command": "npx", "args": ["-y", "parsi-mcp"] } } }

VS Code (.vscode/mcp.json)

{ "servers": { "parsi": { "type": "stdio", "command": "npx", "args": ["-y", "parsi-mcp"] } } }

Agent skill (tells agents to build Persian UIs RTL-first and to call these tools):

npx skills add amirjld/parsi-mcp

From source

git clone https://github.com/amirjld/parsi-mcp.git
cd parsi-mcp && npm install && npm run build
# then use: { "command": "node", "args": ["/absolute/path/to/parsi-mcp/dist/index.js"] }

Before and after

You ask: "Build a checkout page in Persian with a price field."

Without parsi-mcp, agents typically produce an LTR page with margin-left and text-left, a plain number box, and Latin digits.

With parsi-mcp, the agent loads the RTL guidelines, takes rtl_starter_snippet for the layout and price_input_snippet for the field, and validates payment fields with validate_card_number and validate_sheba:

<html lang="fa" dir="rtl">
  <!-- price input: typing 200000 shows ۲۰۰٬۰۰۰ -->
  <input inputmode="numeric" value="۲۰۰٬۰۰۰" />
  <p aria-live="polite">دویست هزار تومان</p>
</html>

Data notes

Bank BINs, Sheba codes, mobile prefixes and province data only include entries confirmed by public sources. Lunar (Hijri) holiday dates, vehicle plate parsing and national-ID city lookup are not included because reliable offline data could not be verified. The VAT helper needs you to supply the rate.

Develop

npm install
npm run build
npm test
npm run docs:tools   # regenerate TOOLS.md (a test fails if it is out of date)

Each tool is a small pure function in src/lib, registered in src/server.ts. Contributions are welcome.
