Claw Patrol, a security firewall for agents

At Deno we've been using OpenClaw and other agents increasingly for addressing production problems in Deno Deploy - when a PagerDuty alert fires, the agent starts researching the cause and making fixes.In order to do this, the agent needs access to real production systems - postgres, kubernetes, gcp, clickhouse, github, etc. But this is dangerous to say the least - we want destructive actions to be reviewed by other LLMs, approved by humans, and logged appropriately.Claw Patrol terminates TCP connections over WireGuard or Tailscale, then parses application protocols (eg http, postgres, ssh) to apply rules that allow you to deny/allow requests.There are a few projects that sit as a proxy in front of agents to do secret injection or apply various guardrails, but none met our needs (LLM gateways, MCP proxies, sandboxes), particularly the need to handle low-level protocols, or handle complex real world situations like tunneling postgres through k8s.Written in Go, configured in HCL, MIT licensed.

Protocol-level firewall that lets AI agents access production systems safely by intercepting and approving destructive actions.

The pain

Companies running AI agents in production (like Deno) need them to access databases, Kubernetes, cloud APIs, and git repos to fix problems automatically. But giving agents direct access to these systems is reckless, they can delete data, corrupt configs, or break infrastructure. Existing solutions (LLM gateways, MCP proxies) work at the API level and can't handle low-level protocols or complex setups like postgres tunneled through Kubernetes.

The gap

No existing tool sits at the TCP/protocol layer to enforce granular rules on agent actions. You either sandbox agents completely (losing utility) or trust them fully (accepting risk). The middle ground, allowing specific safe actions while blocking destructive ones, doesn't exist for complex production architectures.

Build angle

Start with Deno's use case as the anchor customer. They have the problem, they're using it, they can provide feedback on what rules matter most. Build out the rule engine and protocol parsers incrementally. The Go + HCL foundation is solid. Focus on making it dead simple to deploy on existing infrastructure (WireGuard/Tailscale integration is smart). Expand to other companies running agents in production, this will grow as more teams move from experimental to production AI agents.

Strengths

  • Solves a real, specific problem that will only get worse as agent adoption increases
  • Technical approach (TCP interception + protocol parsing) is sound and harder to copy than API-level solutions
  • Already built and in use at a credible company (Deno), not theoretical
  • MIT license and open source positioning builds trust with security-conscious buyers
  • Go + HCL stack is pragmatic and appeals to infrastructure teams
  • Timing is good, agent adoption is accelerating and security concerns are top-of-mind

Risks

  • Market is still small, only companies running agents in production at scale need this. Adoption depends on agent tooling maturity.
  • Requires deep infrastructure knowledge to deploy and configure. Could be a barrier to smaller teams.
  • Protocol parsing is complex and fragile. New protocols or edge cases could break rules unexpectedly.
  • Competitive risk: cloud providers (GCP, AWS) or agent frameworks (Anthropic, OpenAI) could build this into their platforms.
  • Rule configuration could become a support burden. HCL is better than JSON but still requires expertise.
  • Network-level interception can introduce latency or reliability issues if not implemented carefully.
  • Unclear if this is a $10M business or a $100M business. Could be a niche tool that never scales beyond infrastructure teams.
