Agentboard

Search for 'AgentBoard' in the Chrome Web Store and click Install, or use the direct link from the project's GitHub page. The extension is added to Chrome and accessible from the toolbar.

Click the AgentBoard icon in the Chrome toolbar. Go to Settings and add your API key for your preferred provider. You can add multiple providers and switch between them per agent profile.

Set up an agent profile with a system prompt, model selection, temperature, and optional reasoning settings. Profiles let you have specialized agents (e.g., a coding assistant vs. a summarizer) with their own configurations.

Toggle on the built-in tools: agentboard_read_page (converts the current page to markdown), agentboard_youtube_transcript (extracts video transcripts), and agentboard_fetch_url (fetches external URLs). These work on any page without additional setup.

If you have a remote MCP server, add its HTTP streaming URL and optional bearer token in the MCP Servers settings panel. AgentBoard will discover and expose all tools from that server to your agents.

Author a custom tool by writing a JavaScript snippet that interacts with the DOM. Scope it to specific URL patterns (e.g., github.com/*) so it activates only on relevant pages.

// Example: extract all links from the current page
export const tool = {
  name: 'get_page_links',
  description: 'Returns all links on the current page',
  urlPattern: '*://*/*',
  execute: () => {
    return Array.from(document.querySelectorAll('a'))
      .map(a => ({ text: a.innerText, href: a.href }));
  }
};
