This MCP server enables AI assistants like ChatGPT and Claude to perform Vedic astrology calculations. It generates birth charts, determines rising and moon signs, calculates planetary positions, and provides daily panchang data including tithi, nakshatra, and planetary hours based on user-provided birth details or current location.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http cosmic-chemistry-mcp https://cosmicchemistry.co/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add cosmic-chemistry-mcp --url https://cosmicchemistry.co/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cosmic-chemistry-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "cosmic-chemistry-mcp": {
      "url": "https://cosmicchemistry.co/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration
