# Install Starknet MCP Server Set up the Starknet MCP server so Claude can query a live Starknet node. ## Steps 1. The user should provide their Starknet JSON-RPC endpoint URL as `$ARGUMENTS`. If no argument was given, ask the user for their RPC URL. It must be a v0.10.2+ endpoint. 2. Install the Python dependencies: ```bash pip install -r mcp/requirements.txt ``` 3. Ask the user which scope they want: - **Global** (`--scope user`) — available in all projects. Best if they work with Starknet across multiple repos. Requires using the absolute path to `mcp/server.py`. - **Project** (default) — available only in this repo. Uses a relative path. 4. Register the MCP server with Claude Code using the chosen scope. Note that `--env` must come **before** `--` so Claude sets it in the server's environment (anything after `--` is passed as argv to the server itself): - Global: `claude mcp add --scope user --env STARKNET_RPC_URL=<the-url> starknet -- python <absolute-path-to-server.py>` - Project: `claude mcp add --env STARKNET_RPC_URL=<the-url> starknet -- python mcp/server.py` 5. Verify the server is registered by running: ```bash claude mcp list ``` 6. Tell the user the installation is complete and they should restart Claude Code for the new MCP server to take effect. List a few example prompts they can try: - "What's the latest block number on Starknet?" - "Get me the transaction receipt for 0x..." - "What's the ETH token total supply on Starknet?"
