But it certainly wasn&#8217;t on purpose.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Building out what is essentially a digital employee requires it. <\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Time for a little thought experiment. Think about the number of tasks a customer service representative or IT administrator does in a day. Now take those tasks, and think about the <em>tools<\/em> needed. It&#8217;s not always 1:1. A single task can require many tools.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let&#8217;s use a return for this example. The return tool is just the beginning. To complete a return, you also need:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Customer <em>and<\/em> order lookup tools to obtain the information<\/li>\n\n\n\n<li>A KYC tool to make sure you&#8217;re talking to the right person<\/li>\n\n\n\n<li>A shipping label tool to generate a label<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A return requires <em>at least<\/em> four tools to complete, and some tasks might require more. Now, when I say 100 tools, that number might not seem as significant. In reality, Hal and Ben might be only capable of 20 or 30 actual tasks as a result.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, it&#8217;s bad to place all your tools on a single server. But for testing, one &#8220;monolith&#8221; as Kiro has taken to refer to the original MCP server is fine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Also, there is such a thing as too many tools: one beta server also allows you to spot areas of overlap. We were able to spot this much more easily on a single server versus five separate ones, eliminating ~10 tools as a result through merging tools with similar operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&#8217;s also much easier to fix bugs when everything is in one spot. But in a production environment, of course, you want to split things up.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>(I will add to give attackers less of an opportunity to guess your new setup, keep the old MCP running until you&#8217;ve set everything up, then switch over. A stealth deployment makes sense here.)<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Okay, 100+ tools on a single MCP is asking for trouble really quickly.
