| Name | Required | Description | Default |
|---|---|---|---|
| hash | Yes | The block hash to get txid for | |
| index | Yes | The index of the txid in the block |
Implementation Reference
- Core handler implementation that performs the actual API request to retrieve the txid by index using the client.async getBlockTxidByIndex({ hash, index }: { hash: string; index: number }): Promise<string | null> { return this.client.makeRequest<string>(`block/${hash}/txid/${index}`); }
- Helper wrapper in BlocksService that calls the request service and formats the response text.async getBlockTxidByIndex({ hash, index, }: { hash: string; index: number; }): Promise<string> { const data = await this.requestService.getBlockTxidByIndex({ hash, index }); return `Block Txid By Index: ${data}`; }
- Zod schema defining the input parameters for the tool: hash (64-char string) and index (integer).{ hash: z.string().length(64).describe("The block hash to get txid for"), index: z.number().int().describe("The index of the txid in the block"), },
- src/interface/controllers/BlocksToolsController.ts:89-102 (registration)Registers the 'get-block-txid-by-index' tool with the MCP server, including description, schema, and thin handler delegating to BlocksService.private registerGetBlockTxidByIndexHandler(): void { this.server.tool( "get-block-txid-by-index", "Returns txid for a block at a specific index", { hash: z.string().length(64).describe("The block hash to get txid for"), index: z.number().int().describe("The index of the txid in the block"), }, async ({ hash, index }) => { const text = await this.blocksService.getBlockTxidByIndex({ hash, index }); return { content: [{ type: "text", text }] }; } ); }
