server.tool( "web3_clientVersion", "Returns the current client version", {}, async () => { try { const result = await makeRPCCall("web3_clientVersion"); return { content: [ { type: "text", text: formatResponse(result, "Web3 Client Version"), }, ], }; } catch (error: any) { return { content: [ { type: "text", text: `Error: ${error.message}`, }, ], }; } }, ); - src/index.ts:89-96 (helper)Generic helper function used by the web3_clientVersion tool (and others) to perform RPC calls via the ethers JsonRpcProvider.
