ClawWall — Outbound DLP for OpenClaw

GitHub: https://github.com/Stanxy/clawguard Release: https://github.com/Stanxy/clawguard/releases/tag/v0.2.1 PyPI: https://pypi.org/project/clawwall

ClawWall sits between your AI agent and the outside world. Every outbound tool call is intercepted and scanned against 60+ hard-coded patterns before anything leaves the machine. If content matches — it is blocked or redacted. No LLM, no approximation: regex and entropy only.

Trust & Permissions

Be aware of what this installs:

• A local Python service (port 8642) that receives every outbound tool call for scanning
• An OpenClaw plugin that hooks before_tool_call — all outbound content passes through it
• A local SQLite database that stores scan findings metadata

What the database stores: finding type, severity, position offsets, action taken, and duration. It never stores raw content, secrets, or PII values.

What it does NOT do: no telemetry, no external connections, no data leaves the machine. The service is fully local.

Plugin registration is manual — nothing is auto-installed into OpenClaw. You must explicitly add the plugin to your config (see below).

Installation

Prerequisites

• Python 3.10+, pip
• Node.js + npm (for the OpenClaw plugin only)

1. Install the ClawWall service (PyPI)

pip install clawwall==0.2.1

Verify the SHA256 of the downloaded wheel if you want to confirm integrity:

Or clone at the pinned release tag:

git clone --branch v0.2.1 https://github.com/Stanxy/clawguard.git
cd clawguard && pip install .

2. Start the service

clawwall

Or via Python:

python -m clawguard

Service starts on http://localhost:8642. Dashboard at http://localhost:8642/dashboard.

3. Install the OpenClaw plugin (manual)

git clone --branch v0.2.1 https://github.com/Stanxy/clawguard.git
cd clawguard/openclaw-integration/clawguard-plugin
npm install && npm run build

Then manually add to your OpenClaw config:

{
  "plugins": {
    "clawwall": {
      "path": "/path/to/clawguard/openclaw-integration/clawguard-plugin/dist/index.js",
      "config": {
        "serviceUrl": "http://127.0.0.1:8642",
        "blockOnError": false,
        "timeoutMs": 5000
      }
    }
  }
}

Set blockOnError: true to fail-closed (block all tool calls if the service is unreachable). Set blockOnError: false (default) to fail-open (allow calls through if the service is down).

4. (Optional) Install this skill

clawhub install clawwall

Configuration

Environment variables (all prefixed CLAWGUARD_):

What ClawWall Detects

• Secrets (51 patterns): AWS, GCP, Azure, GitHub, Stripe, Slack, PayPal, Square, SSH/PGP private keys, database URIs, JWT tokens, and more
• PII (10 patterns): SSNs, credit cards (Luhn-validated), emails, phone numbers, IP addresses
• Entropy analysis: high-entropy strings that don't match any known pattern

Policy

Default policy (config/default_policy.yaml) blocks all findings:

default_action: BLOCK      # BLOCK | REDACT | ALLOW
redaction:
  strategy: mask           # mask | hash | remove
  mask_char: "*"
  mask_preserve_edges: 4
destination_allowlist: []  # bypass scanning for trusted destinations
destination_blocklist: []  # always reject these destinations
custom_patterns: []        # add your own regex patterns
disabled_patterns: []      # disable specific built-in patterns by name

API Quick Start

curl -s -X POST http://localhost:8642/api/v1/scan \
  -H "Content-Type: application/json" \
  -d '{"content": "key=AKIAIOSFODNN7EXAMPLE", "destination": "api.example.com"}'

Response:

{
  "action": "BLOCK",
  "findings": [{
    "finding_type": "aws_access_key_id",
    "severity": "CRITICAL",
    "redacted_snippet": "AKIA************MPLE"
  }],
  "duration_ms": 2.1
}

Agent Instructions

You are operating behind ClawWall. All outbound tool calls are scanned before leaving the machine using hard pattern matching — not an LLM.

Best practices:

• Never include raw API keys, tokens, or PII in outbound calls
• Reference credentials by name ($OPENAI_API_KEY), not by value
• If blocked, check findings to see what matched, remove it, and retry
• False positive? Tell the user to adjust the policy via the dashboard at http://localhost:8642/dashboard
