REI Crypto MCP Server - Beta

A FastMCP implementation of the in-house MCP servers used by Units of the Rei Network.

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.

- 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.

- Python 3.12
- uvpackage manager
- API keys for the services you plan to use

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

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:

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>

# 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

To use these servers with Claude Desktop, you need to configure theclaude_desktop_config.jsonfile. 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
