Implementation Reference
- Executes the get-block tool by fetching block data using wagmi's getBlock, optionally for a specific chainId and blockNumber, and returns JSON stringified result.execute: async (args) => { const chainId = args.chainId as typeof wagmiConfig['chains'][number]['id'] const blockNumber = args.blockNumber ? BigInt(args.blockNumber) : undefined const result = await getBlock(wagmiConfig, { blockNumber, chainId, includeTransactions: false }) return { content: [ { type: "text", text: JSONStringify(result), }, ], } },
