Implementation Reference
- src/Fetcher.ts:61-88 (handler)The core handler function for the 'fetch_txt' tool. Fetches the HTML, uses JSDOM to strip scripts/styles and extract body textContent, normalizes whitespace, and returns as plain text content.
static async txt(requestPayload: RequestPayload) { try { const response = await this._fetch(requestPayload); const html = await response.text(); const dom = new JSDOM(html); const document = dom.window.document; const scripts = document.getElementsByTagName("script"); const styles = document.getElementsByTagName("style"); Array.from(scripts).forEach((script) => script.remove()); Array.from(styles).forEach((style) => style.remove()); const text = document.body.textContent || ""; const normalizedText = text.replace(/\s+/g, " ").trim(); return { content: [{ type: "text", text: normalizedText }], isError: false, }; } catch (error) { return { content: [{ type: "text", text: (error as Error).message }], isError: true, }; } } - src/index.ts:86-104 (registration)Registration of the 'fetch_txt' tool in the ListTools response, including name, description, and input schema.

import { z } from "zod"; export const RequestPayloadSchema = z.object({ url: z.string().url(), headers: z.record(z.string()).optional(), }); export type RequestPayload = z.infer<typeof RequestPayloadSchema>; - src/Fetcher.ts:6-30 (helper)Private helper method for performing the actual HTTP fetch with custom User-Agent and error handling, used by all Fetcher methods including txt.
