Puppeteer MCP Server

Instructions

Implementation Reference

• index.ts:193-203 (handler)

  The core handler logic for the puppeteer_navigate tool, which navigates the Puppeteer-controlled page to the specified URL and returns a confirmation message.

  case "puppeteer_navigate":
    await page.goto(args.url);
    return {
      content: [
        {
          type: "text",
          text: `Navigated to ${args.url}`,
        },
      ],
      isError: false,
    };

• index.ts:26-32 (schema)

  Defines the input schema for the puppeteer_navigate tool, requiring a single 'url' string parameter.

  inputSchema: {
    type: "object",
    properties: {
      url: { type: "string" },
    },
    required: ["url"],
  },

• index.ts:278-280 (registration)

  Registers the puppeteer_navigate tool (among others) by providing the TOOLS list in response to list tools requests.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: TOOLS,
  }));

• index.ts:282-284 (registration)

  Registers the call tool handler which routes puppeteer_navigate calls to the appropriate switch case in handleToolCall.

  server.setRequestHandler(CallToolRequestSchema, async (request) =>
    handleToolCall(request.params.name, request.params.arguments ?? {})
  );
