• Create Foundry Projects: Initialize new Foundry projects.
• Build Contracts: Compile Solidity contracts with various options.
• Run Tests: Execute tests with detailed configuration.
• Inspect Contracts: Retrieve ABI, bytecode, and other metadata.
• Run Scripts: Execute Solidity scripts.
• Start Local Nodes: Launch Anvil or Chisel for local Ethereum development.
• Advanced Cast Commands: Execute Ethereum-related commands using cast.

To install Foundry MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @lhemerly/foundry-mcp --client claude

1. Clone the repository:

   git clone <repository-url>

2. Ensure Foundry tools (forge, cast, anvil, etc.) are installed and available in your PATH.

To start the MCP server:

python src/eth_wh_mcp/main.py

The following tools are available in the MCP server:

• create_project: Initialize a new Foundry project.
• build_project: Build the current Foundry project.
• test_project: Run tests in the Foundry project.
• clone_contract: Clone a contract from Etherscan.
• run_script: Execute a Solidity script.
• run_cast_command: Run a cast command.
• start_anvil_with_options: Start the Anvil local Ethereum node.
• start_chisel_with_options: Start the Chisel Solidity REPL.
• inspect_contract: Inspect contract metadata.
• snapshot_project: Create a gas usage snapshot.
• coverage_project: Display test coverage.

Refer to the LLM/python-mcp-sdk.md file for detailed usage of the MCP Python SDK, including server construction, tools, prompts, and context handling.

Run the MCP server in development mode:

mcp dev src/eth_wh_mcp/main.py --with-editable .

To execute the server:

python src/eth_wh_mcp/main.py
