Implementation Reference
- src/server/tools.ts:142-152 (handler)The handler function that executes the get_latest_block tool logic. It calls bitcoinService.getLatestBlock() and formats the response as MCP text content.
export async function handleGetLatestBlock(bitcoinService: BitcoinService) { const block = await bitcoinService.getLatestBlock(); return { content: [ { type: "text", text: `Latest block:\nHash: ${block.hash}\nHeight: ${block.height}\nTimestamp: ${block.timestamp}\nTransactions: ${block.txCount}`, }, ] as TextContent[], }; } - src/server/base.ts:146-150 (registration)Registration of the get_latest_block tool in the listTools handler, including name, description, and empty input schema.
{ name: "get_latest_block", description: "Get the latest block", inputSchema: { type: "object", properties: {} }, } as Tool, - src/server/base.ts:209-211 (registration)Dispatcher case in CallToolRequestHandler that routes get_latest_block calls to the handler function.
case "get_latest_block": { return handleGetLatestBlock(this.bitcoinService); } - src/services/bitcoin.ts:173-202 (helper)Supporting utility in BitcoinService that fetches the latest block information from Blockstream API.
async getLatestBlock(): Promise<BlockInfo> { try { const hashRes = await fetch(`${this.apiBase}/blocks/tip/hash`); if (!hashRes.ok) { throw new Error("Failed to fetch latest block hash"); } const hash = await hashRes.text(); const blockRes = await fetch(`${this.apiBase}/block/${hash}`); if (!blockRes.ok) { throw new Error("Failed to fetch block data"); } const block = (await blockRes.json()) as BlockstreamBlock; return { hash: block.id, height: block.height, timestamp: block.timestamp, txCount: block.tx_count, size: block.size, weight: block.weight, }; } catch (error) { logger.error({ error }, "Failed to fetch latest block"); throw new BitcoinError( "Failed to fetch latest block", BitcoinErrorCode.BLOCKCHAIN_ERROR ); } }
