MCP Setup

Connect the Asterwise MCP server to Claude, Cursor, or any MCP-compatible AI system and call all 104 Asterwise tools natively — no API integration code required.

Connection details

Field	Value
MCP URL	https://mcp.asterwise.com/mcp
Auth	OAuth 2.1 — authorization_code + PKCE; clients identify with a Client ID Metadata Document (URL client_id, no secret) or Dynamic Client Registration
Protocol	MCP 2025-06-18
Tools	104 tools covering 118 endpoints

Connect in Claude.ai

1. Go to claude.ai → Settings → Connectors (older versions call it Integrations)
2. Click Add custom connector
3. Enter URL: https://mcp.asterwise.com/mcp
4. Click Connect — you will be redirected to Asterwise OAuth
5. Sign in with your Asterwise account
6. Authorize the connector
7. You are connected — all 104 tools are now available to Claude

Connect in Cursor

Add to your ~/.cursor/mcp.json:

{
  "mcpServers": {
    "asterwise": {
      "url": "https://mcp.asterwise.com/mcp"
    }
  }
}

Restart Cursor. The Asterwise tools will appear in the MCP tools panel.

Available tools

All 104 tools follow a consistent naming convention: asterwise_get_* for chart and compatibility data.

Example tools:

• asterwise_get_natal_chart — full sidereal natal chart
• asterwise_get_dasha — Vimshottari Dasha tree
• asterwise_get_yogas — classical yoga detection
• asterwise_get_panchanga — daily Panchanga elements
• asterwise_get_compatibility — Ashtakoot compatibility with Rajju and Vedha vetoes

Requirements

• An Asterwise account with an active API key
• Any plan, including the free Sandbox tier (500 calls a month). MCP usage counts against the same quota as direct API calls.

Troubleshooting

OAuth redirect fails: Ensure you are logged into asterwise.com before clicking Connect.

Tools not appearing: Restart your MCP client after connecting.

Building your own MCP client? Use an HTTPS URL as your client_id that serves a Client ID Metadata Document (the current MCP standard). No registration call or secret is needed; PKCE S256 is required. A reference document is at asterwise.com/public/oauth/example-client.json.

API errors in tools: Check your plan limits at asterwise.com/dashboard.
