展示HN：Arka – 一个使MCP采纳成为可能的MCP网关
我们创建Arka是因为在实际团队中MCP的采用速度较慢。
同样的三个问题在各处都存在。
1. 上下文变得过于庞大
团队添加了更多的MCP服务器，导致上下文迅速增长。
模型看到的工具过多，选择错误的工具。
准确性下降，工作流程中断。
这阻碍了采用，因为设置在演示中有效，但在实际使用中失败。
2. 设置无法扩展
每个MCP服务器需要自己的配置、端口和认证。
团队最终运行多个服务器，缺乏共享控制。
难以跟踪，容易出错。
大多数团队在这里止步，因为维护所需的时间过长。
3. 缺乏企业安全
没有单点登录（SSO）。没有审计日志。没有用户规则。
大多数团队传递原始令牌。
安全团队阻止了推广。
这在重视合规性的公司中阻碍了MCP的采用。
Arka通过一个网关解决了这些采用问题。
所有MCP服务器的统一设置
• 每个用户一个令牌，支持单点登录（SSO）
• 用户规则和工具规则
• 工具过滤以保持上下文简洁
• 多工具下更好的准确性
• 每次调用都有日志
• 开源或云端
我们还在添加：
• 安全规则下的代理访问
• 可以转换为您自己MCP服务器的工作流程
我们的目标很简单：使MCP的规模化采用成为可能。

We built Arka because MCP adoption is slow in real teams.
The same three problems show up everywhere.<p>1. Context gets too big
Teams add more MCP servers and the context grows fast.
The model sees too many tools and picks the wrong one.
Accuracy drops and workflows break.
This blocks adoption because the setup works in demos but fails in real use.<p>2. Setup does not scale
Each MCP server needs its own config, port, and auth.
Teams end up running many servers with no shared control.
It is hard to track and easy to break.
Most teams stop here because it takes too much time to maintain.<p>3. No enterprise security
No SSO. No audit logs. No user rules.
Most teams pass around raw tokens.
Security teams block the rollout.
This stops MCP adoption in companies that care about compliance.<p>Arka solves these adoption problems with one gateway.<p>One setup for all MCP servers
• One token per user with SSO<p>• User rules and tool rules<p>• Tool filtering to keep context small<p>• Better accuracy with many tools<p>• Logs for every call<p>• Open source or cloud<p>We are also adding:<p>• Agent access with safe rules<p>• Workflows you can convert into your own MCP server<p>Our goal is simple: make MCP adoption possible at scale.<p>Repo: <a href="https://github.com/KenisLabs/arka-mcp-gateway" rel="nofollow">https://github.com/KenisLabs/arka-mcp-gateway</a><p>Cloud: <a href="https://www.kenislabs.com" rel="nofollow">https://www.kenislabs.com</a><p>Would love your feedback!
