Configuration

Quickstart

Add to MCP config:

{
  "mcpServers": {
    "rubic": {
      "command": "npx",
      "args": ["-y", "@cryptorubic/mcp"],
      "env": {
        "EVM_WALLET_PRIVATE_KEY": "YOUR_PRIVATE_KEY"
      }
    }
  }
}

EVM_WALLET_PRIVATE_KEY - EVM private key without 0x. Enables signing/broadcast tools.

Local Installation Options

For read-only mode, omit EVM_WALLET_PRIVATE_KEY.

Option A: Node.js

Requires Node.js v18+.

git clone https://github.com/Cryptorubic/rubic-mcp.git
cd rubic-mcp
npm install
npm run build

Option B: Docker

Pull the published image:

docker pull rubicfinance/rubic-mcp:latest

Or build from source:

git clone https://github.com/Cryptorubic/rubic-mcp.git
cd rubic-mcp
docker build -t rubicfinance/rubic-mcp .

In case of local Node.js installation, copy the example config:

cp .env.example .env

Main settings:

EVM_WALLET_PRIVATE_KEY - EVM private key without 0x. Enables signing/broadcast tools.
RUBIC_API_BASE_URL - Rubic API base URL (default https://rubic-api-v2.rubic.exchange).
TOKENS_API_BASE_URL - Rubic tokens API base URL (default https://api.rubic.exchange/api).
MCP_TRANSPORT - stdio (default) or http.
MCP_HOST / MCP_PORT - used in HTTP mode.
API_TIMEOUT_MS / MCP_TOOL_TIMEOUT_MS - request and tool execution timeouts.

Without EVM_WALLET_PRIVATE_KEY, read-only and build tools work, but tools that sign transactions will return an error.

Connecting to MCP Clients

Quickstart section is enough for the most use cases. All of the instructions below are related to local installation options. All examples below use stdio mode. Replace /full/path/to with the actual path printed after npm run build. Claude Code

# With private key
claude mcp add rubic -e EVM_WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY -- node /full/path/to/dist/index.js

# Read-only / unsigned mode
claude mcp add rubic -- node /full/path/to/dist/index.js

Using Docker:

claude mcp add rubic -e EVM_WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY -- docker run -i --rm rubicfinance/rubic-mcp:latest node dist/index.js

Other clients (generic stdio)

Use command node + args ["/full/path/to/dist/index.js"], or Docker command:

docker run -i --rm -e EVM_WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY rubicfinance/rubic-mcp:latest node dist/index.js

Hosted MCP

Use hosted read-only MCP endpoint: https://mcp-api-v2.rubic.exchange/mcp Example generic MCP config:

{
  "mcpServers": {
    "rubic": {
      "url": "https://mcp-api-v2.rubic.exchange/mcp"
    }
  }
}

Transport modes

Node.js

# stdio (default)
npm start

# HTTP mode
MCP_TRANSPORT=http npm run start:http

Docker

# stdio
docker run -i --rm -e EVM_WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY rubicfinance/rubic-mcp:latest node dist/index.js

# HTTP mode
