WivenLLM in<br \/>\nis a client: any MCP server can be connected, and its tools become<br \/>\nskills that can be used by your agents.<\/p>\n<hr \/>\n<h2>What is it for?<\/h2>\n<p>Without MCP, connecting WivenLLM to an internal tool requires development<br \/>\nspecific. With MCP, the tool simply needs to expose a server that complies with the<br \/>\nstandard: WivenLLM queries the server, discovers the available functions, and<br \/>\nthey propose them to the agents.<\/p>\n<p>The advantage: the MCP ecosystem is shared. One server is written for another.<br \/>\nThe application works here, and vice versa.<\/p>\n<p><strong>Examples of what is connected like this:<\/strong> a ticketing system, an ERP, a tool<br \/>\nproject management, an internal service, a proprietary document database.<\/p>\n<hr \/>\n<h2>Configure \u2014 <em>administrator<\/em><\/h2>\n<p><code>Settings \u2192 Agents<\/code>, MCP servers section.<\/p>\n<p>An MCP server can be declared in two ways:<\/p>\n<p><strong>Local server.<\/strong> WivenLLM starts the program and communicates with him<br \/>\ndirectly.

The URL is declared.<br \/>\nand, where applicable, the authentication headers.<\/p>\n<p>Once declared, the server is started on demand and its tools appear<br \/>\nin the list of skills, ready to be activated per workspace.<\/p>\n<hr \/>\n<h2>Life cycle<\/h2>\n<ul>\n<li>The servers are <strong>started on demand<\/strong>, when an agent needs it.<\/li>\n<li>The administration screen displays their <strong>state<\/strong> and allows them to be restarted.<\/li>\n<li>A server is unavailable <strong>does not prevent<\/strong> the agents to function: the<br \/>\n  The corresponding tools are simply missing.<\/li>\n<\/ul>\n<hr \/>\n<h2>Points to consider<\/h2>\n<p><strong>An MCP server runs with the permissions you give it.<\/strong> A server<br \/>\nThe local server runs on your machine; a remote server receives what the agent tells it<br \/>\ntransmit.
