Stablecoins: Retrieve dominance metrics, circulating amounts, historical market cap, and chain distributions
Yields: Get yield pools, historical APY, borrow costs, perpetuals funding rates, and LSD rates
Bridges: View bridge volumes, transactions, summaries, and daily statistics
Derivatives: Query volumes, summaries, and historical data for derivative protocols
Prices: Fetch current and historical token prices, charts, and percentage changes
DEX: Analyze volumes and historical data for decentralized exchanges and options protocols
ETFs: Access metrics, historical AUM, and overviews for BTC and ETH ETFs
Protocol Fees: Get summaries of protocol fees and revenue with historical data
User Data: Retrieve active users and user-specific data by protocol

REI Crypto MCP Server - 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
Elfa AI API
Codex API

Codex at the moment is just used for searching a contract address from the name. Deeper implementation will come in the near future. Codex uses GraphQL for it's query system. Edit the query to hardcode some parameters in case you need stricter filtering.

Prerequisites

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

Installation

Clone the repository:

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

Install uv (if not already installed):

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

Create and activate a virtual environment with uv:

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

Install dependencies from pyproject.toml:

uv pip install .

Set up your environment variables:

cp .env_example .env

Edit .env with your API keys:

ARKHAM_API_KEY=<YOUR ARKHAM_API_KEY> CG_API_KEY=<YOUR_CG_API_KEY> DEFILLAMA_API_KEY=<YOUR_DEFILLAMA_API_KEY> CODEX_API_KEY=<YOUR_CODEX_API_KEY> ELFA_API_KEY=<YOUR_ELFA_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 # Run Codex server uv run codex_server.py # Run Elfa AI server uv run elfa_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" ] }, "codex": { "command": "ssh", "args": [ "user@your-host", "cd /path/to/crypto_mcp && /path/to/uv run codex_server.py" ] }, "elfa": { "command": "ssh", "args": [ "user@your-host", "cd /path/to/crypto_mcp && /path/to/uv run elfa_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)
