Implementation Reference

• src/tools/upstream.ts:17-33 (handler)

  The handler function for the `proxy_set_upstream` tool. It calls `proxyManager.setGlobalUpstream` to apply the proxy configuration.

  async ({ proxy_url, no_proxy }) => {
    try {
      await proxyManager.setGlobalUpstream({ proxyUrl: proxy_url, noProxy: no_proxy });
      return {
        content: [{
          type: "text",
          text: JSON.stringify({
            status: "success",
            message: `Global upstream set to ${proxy_url}`,
            noProxy: no_proxy || [],
          }),
        }],
      };
    } catch (e) {
      return { content: [{ type: "text", text: JSON.stringify({ status: "error", error: String(e) }) }] };
    }
  },

• src/tools/upstream.ts:11-16 (registration)

  The tool registration definition for `proxy_set_upstream`, including its description and input schema using Zod.

  "proxy_set_upstream",
  "Set a global upstream proxy for all outgoing traffic. Supports socks4://, socks5://, http://, https://, and pac+http:// URLs.",
  {
    proxy_url: z.string().describe("Upstream proxy URL (e.g., socks5://user:pass@host:port)"),
    no_proxy: z.array(z.string()).optional().describe("Hostnames to bypass the upstream proxy"),
  },
