Chromia Wallet MCP server for AI agents

This tool enables Claude AI to interact with Chromia Wallet for sending $CHR transactions, serving as an implementation of the Model Context Protocol (MCP). It allows Claude to interface directly with blockchain functionality through your wallet.

Installation

Prerequisites

Node.js installed on your system
Claude Desktop App (if using with Claude)
Git

Setup Steps

Clone the repository:

git clone https://github.com/username/chromia-mcp.git
cd chromia-mcp

Create and configure the environment file:
```
cp .env.sample .env
```
Install dependencies and build the project:
```
npm i
npm run build
```

Configuration with Claude Desktop App

For macOS

Edit Claude's configuration file:

nano ~/Library/Application\ Support/Claude/claude_desktop_config.json

Add the MCP server configuration:

{
    "mcpServers": {
        "chromia-mcp": {
            "command": "node",
            "args": [
                "/PATH_TO_FOLDER/chromia-mcp/build/index.js"
            ]
        }
    }
}

Note: Replace /PATH_TO_FOLDER with the actual path to where you cloned the repository.

Restart the Claude Desktop App for changes to take effect.

Usage

Once set up, Claude can interact with your Chromia Wallet to perform transactions. You can ask Claude to:

Check your $CHR balance
Send $CHR to other wallets
Verify transaction status

Simply ask Claude to perform these actions in natural language, and the MCP server will facilitate the communication between Claude and your Chromia Wallet.

Example Interactions

"Can you check my Chromia wallet balance?"
"Please send 5 CHR to address 0x..."
"Show me my recent Chromia transactions"

The MCP integration allows Claude to securely interact with your wallet while maintaining your control over transaction confirmation.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "chromia-mcp" '{"command":"node","args":["/PATH_TO_FOLDER/chromia-mcp/build/index.js"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "chromia-mcp": {
            "command": "node",
            "args": [
                "/PATH_TO_FOLDER/chromia-mcp/build/index.js"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "chromia-mcp": {
            "command": "node",
            "args": [
                "/PATH_TO_FOLDER/chromia-mcp/build/index.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
