crypto mcp beta

FastMCP implementation of the in-house MCP servers used by Units of the Rei Network. You can use them without providing API keys at app.reisearch.box or you can use them with other MCP clients deploying them yourself.

Everything is to be considered still in beta. Expect things to be added or changed with no warnings.

Current MCP servers:

• DefiLlama Pro API
• CoinGecko Pro API
• Arkham Intelligence API

Prerequisites

• Python 3.12
• uv package manager
• API keys for the services you plan to use

Installation

1. Clone the repository:

   git clone https://github.com/0xReisearch/crypto-mcp-beta
   cd crypto-mcp-beta

2. Install uv (if not already installed):

   curl -LsSf https://astral.sh/uv/install.sh | sh

3. Create and activate a virtual environment with uv:

   uv venv
   source .venv/bin/activate  # On Unix/macOS
   # or
   .venvScriptsactivate  # On Windows

4. Install dependencies from pyproject.toml:

   uv pip install .

5. Set up your environment variables:

   cp .env_example .env

Edit .env with your API keys:

DEFILLAMA_API_KEY=your_defillama_api_key
CG_API_KEY=your_coingecko_api_key
ARKHAM_API_KEY=your_arkham_api_key

Running the Servers

You can run each server individually:

# Run DefiLlama server
uv run defillama_server.py

# Run CoinGecko server
uv run cg_server.py

# Run Arkham server
uv run arkham_server.py

Configuring Claude Desktop

To use these servers with Claude Desktop, you need to configure the claude_desktop_config.json file. This file is typically located in: - Windows: %APPDATA%/claude-desktop/claude_desktop_config.json - macOS: ~/Library/Application Support/claude-desktop/claude_desktop_config.json - Linux: ~/.config/claude-desktop/claude_desktop_config.json

Example configuration:

{
    "mcpServers": {
        "arkham": {
            "command": "ssh",
            "args": [
                "user@your-host",
                "cd /path/to/crypto_mcp && /path/to/uv run arkham_server.py"
            ]
        },
        "coingecko": {
            "command": "ssh",
            "args": [
                "user@your-host",
                "cd /path/to/crypto_mcp && /path/to/uv run cg_server.py"
            ]
        },
        "defillama": {
            "command": "ssh",
            "args": [
                "user@your-host",
                "cd /path/to/crypto_mcp && /path/to/uv run defillama_server.py"
            ]
        }
    }
}

Replace the following: - user@your-host: Your SSH username and host - /path/to/crypto_mcp: The absolute path to where you cloned this repository - /path/to/uv: The absolute path to your uv installation (usually in ~/.local/bin/uv on Unix systems)
