Raindex MCP Server

A Model Context Protocol (MCP) server that wraps the Raindex SDK (@rainlanguage/orderbook), enabling AI agents to query, manage, and interact with Raindex onchain orderbook positions.

Features

  • 17 MCP tools covering orders, vaults, strategies, deployment, transactions, and token info

  • Calldata-only writes — never holds keys or signs transactions

  • Multi-chain — queries all configured chains from a single settings file

  • Registry integration — browse and deploy strategies from a dotrain registry

Prerequisites

  • Nix with flakes enabled

  • A Raindex settings YAML file (see example)

Setup

# Enter dev shell (provides Node.js 22)
nix develop

# Install dependencies
npm ci

# Build
npm run build

# Run tests
npm test

Configuration

Set environment variables before starting the server:

Variable

Required

Description

RAINDEX_SETTINGS_PATH

Inline YAML settings string

RAINDEX_REGISTRY_URL

No

URL to a dotrain registry manifest

*One of RAINDEX_SETTINGS_PATH or RAINDEX_SETTINGS_YAML is required.

MCP client configuration (e.g. Claude Desktop)

{
  "mcpServers": {
    "raindex": {
      "command": "node",
      "args": ["/path/to/raindex-mcp/dist/index.js"],
      "env": {
        "RAINDEX_SETTINGS_PATH": "/path/to/settings.yaml",
        "RAINDEX_REGISTRY_URL": "https://example.com/registry.txt"
      }
    }
  }
}
