Implementation Reference
- src/tools.ts:126-139 (schema)Tool schema definition including name, description, and input schema for 'pptx-to-markdown'.
export const PptxToMarkdownTool = ToolSchema.parse({ name: "pptx-to-markdown", description: "Convert a PPTX file to markdown", inputSchema: { type: "object", properties: { filepath: { type: "string", description: "Absolute path of the PPTX file to convert", }, }, required: ["filepath"], }, }); - src/server.ts:33-37 (registration)Registers the pptx-to-markdown tool (among others exported from tools.ts) for listing via MCP protocol.
server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: Object.values(tools), }; }); - src/server.ts:72-86 (handler)Handler dispatch for pptx-to-markdown tool call: validates input filepath and invokes Markdownify.toMarkdown for conversion.
