Implementation Reference

• tools-playwright.js:27-30 (handler)

  Handler function for the 'navigate' MCP tool. Destructures the input URL and delegates to the browser wrapper's navigate method, returning a success response with confirmation message.

  handler: async ({ url }) => {
    await browser.navigate(url);
    return { success: true, message: `Navigated to ${url}` };
  }

• tools-playwright.js:20-26 (schema)

  Input schema definition for the 'navigate' tool, specifying a required 'url' parameter of type string.

  inputSchema: {
    type: 'object',
    properties: {
      url: { type: 'string', description: 'The URL to navigate to' }
    },
    required: ['url']
  },

• tools-playwright.js:17-31 (registration)

  Complete registration object for the 'navigate' tool within the createPlaywrightTools function's returned array. This object is included in the main tools list used by the MCP server.

  {
    name: 'navigate',
    description: 'Navigate to a URL',
    inputSchema: {
      type: 'object',
      properties: {
        url: { type: 'string', description: 'The URL to navigate to' }
      },
      required: ['url']
    },
    handler: async ({ url }) => {
      await browser.navigate(url);
      return { success: true, message: `Navigated to ${url}` };
    }
  },

• browser.js:64-67 (helper)

  Supporting 'navigate' method in SimpleBrowser class. Ensures browser is launched and uses Playwright's page.goto to navigate to the specified URL.

  async navigate(url) {
    await this.ensureLaunched();
    await this.page.goto(url);
  }

• index.js:74-76 (registration)

  Final registration step in MCP server initialization: calls createTools (which includes 'navigate') to populate the tools array used in MCP tool listing and execution handlers.

  // Register all available automation tools
  const tools = createTools(browser);
