Install Drasil

Pick your platform. One step setup — no signup, no API key management.

Claude Desktop

Claude.ai

Claude Code

REST API

Step 1 — Open Config

Settings → Developer → Edit Config

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

Step 2 — Paste Config

Add this to your config file:

{
  "mcpServers": {
    "drasil": {
      "type": "url",
      "url": "https://mcp.yggdrasilapi.com/DRASIL-PerfectMathTrialExpiresMay042026"
    }
  }
}

Step 3 — Restart

Restart Claude Desktop. The drasil_protocol and drasil_status tools appear in the tools menu. Ask any math problem.

Step 1 — Add Integration

Go to claude.ai → Settings → Integrations → Add MCP Server

Step 2 — Paste URL

Enter this server URL:

https://mcp.yggdrasilapi.com/DRASIL-PerfectMathTrialExpiresMay042026

Step 3 — Ask

Start a new conversation. Ask any math problem. Claude automatically calls the drasil_protocol tool, loads the reasoning protocol, and solves with exact arithmetic.

One Command

Run this in your terminal:

claude mcp add drasil --transport http https://mcp.yggdrasilapi.com/DRASIL-PerfectMathTrialExpiresMay042026

Done

The drasil_protocol tool is now available in every Claude Code session. Ask any math problem.

MCP JSON-RPC

curl -X POST https://mcp.yggdrasilapi.com/DRASIL-PerfectMathTrialExpiresMay042026 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"drasil_protocol"}}'

drasil_protocol

Loads the full Drasil math reasoning protocol (190 lines). Call before solving any math problem. The protocol is ephemeral — used once, then discarded.

drasil_status

Returns your license tier, server version, and benchmark results (1,919/1,919 — 100% on GSM8K, MATH-500, and Arithmetic).

Test Connection

Verify the MCP server is live and returning the protocol.
