OpenClaw Skill

NullBore ships an OpenClaw skill that lets AI agents manage tunnels programmatically.

Install the skill

Download the skill file and install it:

# Download from GitHub
curl -LO https://github.com/nullbore/nullbore-openclaw-skill/releases/latest/download/nullbore-openclaw-skill.skill

# Install (copy to your skills directory)
cp nullbore-openclaw-skill.skill ~/.openclaw/skills/

Configuration

Set these environment variables for OpenClaw:

NULLBORE_SERVER=https://tunnel.nullbore.com
NULLBORE_API_KEY=nbk_your_key_here

What the agent can do

Once installed, your OpenClaw agent can:

• Open tunnels: "Expose port 3000 for 2 hours"
• Open with idle TTL: "Expose my MCP server, keep it alive while there's traffic"
• List tunnels: "What tunnels are running?"
• Close tunnels: "Close the myapp tunnel"
• Extend tunnels: "Give the API tunnel another 4 hours"
• Clean up: "Close all my tunnels"

Example conversations

User: Expose port 4000 so my cloud agent can reach my local MCP server

Agent: Opens a tunnel with idle TTL:

curl -X POST https://tunnel.nullbore.com/v1/tunnels \
  -H "Authorization: Bearer $NULLBORE_API_KEY" \
  -d '{"local_port": 4000, "ttl": "1h", "idle_ttl": true}'
# → https://a7f3bc.tunnel.nullbore.com

User: What tunnels do I have running?

Agent: Lists active tunnels via GET /v1/tunnels and reports status, traffic, and expiry times.
