Celo MCP Server

A Model Context Protocol (MCP) server for interacting with the Celo blockchain. This server provides comprehensive access to Celo blockchain data, token operations, NFT management, smart contract interactions, transaction handling, and governance operations.

Installation

1. Clone the repository:

git clone https://github.com/celo-org/celo-mcp
cd celo-mcp

2. Install dependencies:

pip install -e .

3. Set up environment variables (optional):

export CELO_RPC_URL="https://forno.celo.org"  # Default: Celo mainnet

MCP Integration

Cursor IDE Integration

To use this MCP server with Cursor IDE, add the following configuration to your MCP settings file (~/.cursor/mcp.json):

{
  "mcpServers": {
    "celo-mcp": {
      "command": "uvx",
      "args": [
        "--refresh",
        "celo-mcp"
      ]
    }
  }
}

The --refresh flag ensures that the latest code is always loaded when the MCP server starts.

Claude Desktop Integration

For Claude Desktop, add this configuration to your MCP settings file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "celo-mcp": {
      "command": "uvx",
      "args": [
        "--refresh",
        "celo-mcp"
      ]
    }
  }
}

Usage

Running the Server

# Run the MCP server
python -m celo_mcp.server

# Or use the CLI entry point
