RishiAI MCP Server

A Model Context Protocol server that exposes Vedic astrology tools powered by the DashaFlow calculation engine.

Works with any MCP-compatible client — VS Code Copilot, Cursor, Claude Desktop, Claude Code, Gemini CLI, Codex, Antigravity, OpenCode, OpenClaw, Pi agent, or any custom app that speaks MCP.

Install

pip install rishi-ai-mcp

Quick Start

rishi-ai-mcp                    # console entry point (after pip install)
python rishi_ai_mcp.py          # or run directly from source

Communicates over stdio. Any MCP client that can spawn a subprocess and speak MCP can use it — no IDE required.

Setup

Clone this repo into your workspace to get the MCP config + RishiAI agent rules for your IDE:

git clone https://github.com/adarshj322/rishi-ai-mcp.git

The repo includes ready-to-use configs for three IDEs:

VS Code / GitHub Copilot

• .vscode/mcp.json — auto-configures the MCP server
• .github/copilot-instructions.md — RishiAI persona (always-on)
• .agents/skills/*/SKILL.md — 14 workflow skills (auto-triggered by topic, or invoke via /skill-name)

VS Code Copilot reads .github/copilot-instructions.md for always-on instructions and .agents/skills/ for skills. Just open the cloned folder and the tools + persona + skills are active.

Cursor

• .cursor/mcp.json — auto-configures the MCP server
• .cursor/rules/rishi-ai.mdc — RishiAI persona (always-on core rule)
• .agents/skills/*/SKILL.md — 14 workflow skills (shared, Cursor reads .agents/skills/ natively)

Open the cloned folder in Cursor and the tools + persona + skills are active.

Antigravity

• .agents/rules/rishi-ai.md — RishiAI persona (always-on)
• .agents/skills/*/SKILL.md — 14 workflow skills
• .agents/workflows/*.md — 14 slash-command workflows

Antigravity reads .agents/ natively. Configure the MCP server in your Antigravity settings:

command: uvx
args: rishi-ai-mcp

Other MCP Clients (Claude Desktop, Claude Code, Gemini CLI, etc.)

Any MCP-compatible client can connect using the same server. Add to your client's MCP config:

{
  "mcpServers": {
    "vedic-astrology": {
      "command": "uvx",
      "args": ["rishi-ai-mcp"]
    }
  }
}

For the RishiAI persona, use system_prompt.md as a reference and adapt it to your client's instruction format.

Standalone / Custom Client

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

params = StdioServerParameters(command="uvx", args=["rishi-ai-mcp"])

async with stdio_client(params) as (read, write):
    async with ClientSession(read, write) as session:
        await session.initialize()
        result = await session.call_tool("cast_vedic_chart", {
            "dob": "1990-04-15", "time": "14:30",
            "lat": 28.6139, "lon": 77.2090, "timezone": "Asia/Kolkata"
        })
        print(result)
