Installation
Install Bun. Clone this repo. Install the dependencies with bun install. Update Claude's MCP config - see instructions for your particular OS. You'll want something like this in the claude_desktop_config.json file:
{
"mcpServers": {
"starknet": {
"command": "bun",
"args": ["/PATH/TO/THIS/REPO/starknet-mcp/index.ts"],
"env": {
"STARKNET_RPC_URL": "https://starknet-mainnet.public.blastapi.io/rpc/v0_7"
}
}
}
}
Usage
After correctly configuring Claude Desktop, it will have access to all the available methods. You can start asking Claude questions about the state of the chain, e.g. "What is the latest block hash and number on Starknet?". If Claude determines it has to use an MCP method to answer your question, it will ask you for permissions:
You'll see the used method, its input and output inline in the chat.
Quirks
Methods starknet_estimateFee and starknet_estimateMessageFee are not yet supported.
Claude doesn't 100% follow the tool inputSchema. It prefers sending strings over anything else. Some of this is prevented in the code, but if you encounter any error, please open an issue.
