Kundlit Vedic Astrology — MCP Server

Free Vedic astrology computation for AI assistants over the Model Context Protocol: daily panchang and muhurta timings for any city, janam kundali birth charts, kundli milan (ashtakoot) matching, dosha checks, dasha periods, transits, festival and eclipse calendars, and Vedic numerology — 17 tools (discovered dynamically), plus prompts and documentation resources.

Results are deterministic — computed live with the Swiss Ephemeris on the sidereal zodiac (Lahiri ayanamsa) — and backed by classical-text citations on kundlit.com.

• Server URL: https://kundlit.com/api/mcp (hosted, Streamable HTTP)

• Auth: none — no account, no API key

• Rate limit: 30 requests/minute/IP

• Docs: https://kundlit.com/mcp

• Privacy: https://kundlit.com/privacy · Support: support@kundlit.com

Install

1. npx (works with every client, including stdio-only ones)

npx -y @kundlit/mcp

That starts a local stdio MCP server which proxies to the hosted endpoint. Point any client at it by command:

Claude Desktop — claude_desktop_config.json:

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

Cursor — .cursor/mcp.json, or any client that reads a generic .mcp.json:

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

Installed globally (npm i -g @kundlit/mcp) the binary is kundlit-mcp, so "command": "kundlit-mcp" with no args works too.

2. Direct Streamable HTTP (clients with remote-server support)

No bridge process needed — connect straight to the URL.

Claude Code:

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

Config file:

{
  "mcpServers": {
    "kundlit-astro": {
      "url": "https://kundlit.com/api/mcp"
    }
  }
}

What is in this repository

The npm package @kundlit/mcp published from here is a thin client: a bidirectional JSON-RPC pump between a local StdioServerTransport and a StreamableHTTPClientTransport aimed at https://kundlit.com/api/mcp. It contains no astrology logic and no copy of the tool list — every frame is forwarded verbatim, so tools added or renamed on the hosted server are picked up with no package update.

The astrology server itself is hosted at kundlit.com and its source is not public. The manifests here (.mcp.json, server.json, .plugin/plugin.json) exist so MCP clients, registries and directories can discover and install it.

Bridge options

kundlit-mcp [--url <endpoint>]

  --url <endpoint>   Hosted MCP endpoint (default https://kundlit.com/api/mcp).
                     Also settable via KUNDLIT_MCP_URL; --url wins.
  -h, --help         Usage and a config snippet.
  -v, --version      Package version.

stdout carries JSON-RPC and nothing else; all diagnostics, including --help and --version output, go to stderr. Requires Node.js 18 or newer.

Docker

docker build -t kundlit-mcp .
docker run -i --rm kundlit-mcp

The container speaks MCP over stdio, so run it with -i and no TTY.

Development

npm install
node scripts/smoke.mjs   # end-to-end check against the live hosted server

Capabilities

17 tools, discovered dynamically via tools/list — panchang, muhurta and choghadiya windows, janam kundali, ashtakoot matching, manglik / kaal sarp / sade sati checks, dasha periods, transits, pancha pakshi, year events, eclipses, and numerology. Prompts and documentation resources (kundlit://docs/methodology, kundlit://docs/usage-guide) are likewise discovered at runtime; ask your client to list them rather than relying on a list in this README.

Example prompts

• "What is today's panchang in Jaipur? When is rahu kaal?"

• "Make a janam kundali for 14 March 1992, 6:45 am, Lucknow — which mahadasha am I running?"

• "Find me a good time tomorrow in Pune to sign a lease — avoid rahu kaal and bhadra."

• "All ekadashi dates in 2026 for Varanasi."

Notes

• Free-text place (any city worldwide) is preferred; latitude/longitude/IANA timezone also accepted. Year tools snap to the nearest of 50 supported cities.

• Results are informational and not a substitute for professional advice.

• Every result carries a Source: attribution line — please keep it intact; that attribution is the price of free access.
