Implementation Reference

• src/server.ts:313-327 (registration)

  Registration of the 'set_cookies' tool including name, description, and input schema requiring a 'cookies' string.

  {
    name: "set_cookies",
    description: "Set authentication cookies for N Lobby access",
    inputSchema: {
      type: "object",
      properties: {
        cookies: {
          type: "string",
          description:
            "Cookie string from authenticated N Lobby session",
        },
      },
      required: ["cookies"],
    },
  },

• src/server.ts:882-893 (handler)

  MCP tool handler for 'set_cookies': extracts cookies from input arguments, calls api.setCookies(cookies), and returns success message.

  case "set_cookies": {
    const { cookies } = args as { cookies: string };
    this.api.setCookies(cookies);
    return {
      content: [
        {
          type: "text",
          text: "Authentication cookies have been set. You can now access real N Lobby data.",
        },
      ],
    };
  }

• src/nextauth.ts:35-42 (helper)

  NextAuthHandler.setCookies method parses the provided cookie string into sessionToken, csrfToken, and callbackUrl using parseCookies.

  setCookies(cookieString: string): void {
    this.cookies = this.parseCookies(cookieString);
    logger.debug("NextAuth cookies parsed:", {
      hasSessionToken: !!this.cookies.sessionToken,
      hasCsrfToken: !!this.cookies.csrfToken,
      hasCallbackUrl: !!this.cookies.callbackUrl,
    });
  }
