• src/tools/rules.ts:82-111 (handler)

  The handler implementation for the `proxy_update_rule` tool, which calls `proxyManager.updateRule`.

  server.tool(
    "proxy_update_rule",
    "Modify an existing interception rule.",
    {
      rule_id: z.string().describe("Rule ID to update"),
      description: z.string().optional().describe("New description"),
      priority: z.number().optional().describe("New priority"),
      matcher: matcherSchema.optional().describe("New matcher config"),
      handler: handlerSchema.optional().describe("New handler config"),
    },
    async ({ rule_id, description, priority, matcher, handler }) => {
      try {
        const updates: Record<string, unknown> = {};
        if (description !== undefined) updates.description = description;
        if (priority !== undefined) updates.priority = priority;
        if (matcher !== undefined) updates.matcher = matcher;
        if (handler !== undefined) updates.handler = handler;
  
        const rule = await proxyManager.updateRule(rule_id, updates);
        return {
          content: [{
            type: "text",
            text: JSON.stringify({ status: "success", rule }),
          }],
        };
      } catch (e) {
        return { content: [{ type: "text", text: JSON.stringify({ status: "error", error: String(e) }) }] };
      }
    },
