PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "saroday": {
      "command": "npx",
      "args": [
        "-y",
        "@saroday/mcp-server"
      ]
    }
  }
}

Run this in your terminal

claude mcp add saroday -- npx -y @saroday/mcp-server

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "saroday": {
      "command": "npx",
      "args": [
        "-y",
        "@saroday/mcp-server"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "saroday": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@saroday/mcp-server"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Saroday MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

@saroday/mcp-server

MCP (Model Context Protocol) server for Saroday — Korean Saju (사주) calculation and myeongni-hak (命理學) glossary lookup.

This MCP server lets Claude Desktop, Cline, Cursor, and any other MCP-compatible AI client perform accurate Korean Saju (Four Pillars of Destiny) calculation by calling the public Saroday API under the hood.


What it does

When connected, the AI client gains access to four tools:

ToolDescription
calculate_sajuCompute full Saju analysis (8 characters, sipseong, sinsal, hapchung, 12-unseong, yongshin, daeun) from birth date / time / gender.
lookup_glossaryLook up any of 80+ myeongni-hak terms (도화살, 천을귀인, 식신, 육합, etc.) with full Korean explanation.
get_daily_fortuneToday's fortune for one of 12 Western zodiac signs or 12 Chinese zodiac signs. Cached server-side, fast response.
discover_saroday_apiList available Saroday API endpoints and metadata.

Why this matters: ChatGPT, Claude, and other LLMs frequently miscalculate Saju when asked directly because manse-ryeok (萬歲曆) lookup and 절기 (jeolgi) boundary handling require precise data. This MCP delegates the math to a verified server while letting the AI focus on the interpretation.


Installation

Option A — npx (no install)
npx @saroday/mcp-server
Option B — global install
npm install -g @saroday/mcp-server

saroday-mcp

Option C — clone and run
git clone https://github.com/saroday/mcp-server.git

cd mcp-server npm install node index.js

Requires Node.js 18 or newer.


Configure Claude Desktop

Edit your Claude Desktop config file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

Add (or merge) the following:

{

"mcpServers": { "saroday": { "command": "npx", "args": ["-y", "@saroday/mcp-server"] } } }

Restart Claude Desktop. You should see "saroday" listed in the MCP servers panel (the plug icon in the input area).

Local development (running from cloned repo)
{

"mcpServers": { "saroday": { "command": "node", "args": ["/absolute/path/to/mcp-server/index.js"] } } }


Configure Cline / Cursor / other MCP clients

Any MCP client that supports stdio transport works. Point it at the saroday-mcp binary or node index.js. See your client's docs for the exact config format.


Try it out

After connecting, ask Claude things like:

  • *"My birthday is March 15, 1992 at 10am. Calculate my Korean Saju."*
  • *"What does 도화살 (dohwa-sal) mean in Korean fortune-telling?"*
  • *"내 사주 봐줘. 1990년 5월 20일 음력 14시 여성."*
  • *"제왕(jeokwang) 12-unseong이 뭐야?"*

Claude will automatically invoke calculate_saju or lookup_glossary and give you a polished interpretation based on the structured data returned.


Environment variables

VariableDefaultPurpose
SARODAY_API_BASEhttps://saroday.comOverride the API base URL (e.g., for self-hosted or staging environments).

Rate limits

The public Saroday API allows 100 requests per hour per IP for free use. Heavy users — apps shipping to many end-users, AI agents handling many concurrent users — should request an API key (coming soon) for higher quotas.

How it works

[User in Claude Desktop]

↓ types "내 사주 봐줘" [Claude Desktop] ↓ calls calculate_saju via MCP stdio [saroday-mcp (this package, runs locally)] ↓ HTTPS POST /api/v1/saju [saroday.com server] ↓ runs verified manse-ryeok algorithm [result JSON] ↑ flows back through the chain [Claude] writes a beautiful Korean interpretation

This MCP package is a thin adapter — all calculation lives on Saroday's servers, so updates to the algorithm or glossary roll out without you having to upgrade the package.


Differentiators

  • Manse-ryeok accuracy — handles 절기 (solar terms) boundaries that LLMs routinely get wrong (verified against @fullstackfamily/manseryeok library)
  • 80+ glossary entries (~400 interpretation fields) — every sinsal, hapchung, sipseong, 12-unseong term has summary / meaning / positive / negative / practical-tip interpretation written in friendly Korean
  • Korean myeongni-hak tradition — based on 적천수(滴天髓), 자평진전(子平真詮), 궁통보감(窮通寶鑑) references
  • Three-channel exposure — same algorithm available as web service (saroday.com), public REST API (saroday.com/api/v1), and MCP server (this package). Pick the channel that fits your integration.
