ClawKeeper

Host-agnostic safety middleware for tool-using agentic systems (can be wired into Hermes Agent, MCP tools, HTTP bridges, OpenClaw-style runtimes, or a custom host).

ClawKeeper sits between an agent and its tools. It can block risky tool calls, redact sensitive tool results, remember recurring attack patterns & self improve guardrail layers, and delegate harder trajectory-level decisions to an external Watcher.

What it is for

• Guarding shell, Python, browser, filesystem, and network tool calls before execution.
• Catching common agent-security failures: prompt injection, credential reads, credential exfiltration chains, unsafe shell execution, protected-path access, SSRF-like URLs, encoded second-stage payloads, and poisoned tool output.
• Running a host-independent Judge API for non-Python adapters.
• Running an optional Watcher daemon that reasons over intent, recent tool history, deterministic findings, and proposed tool calls.
• Self-improving guard coverage: Watcher catches can synthesize learned patterns, persist them under ~/.clawkeeper/, and hot-reload them into the live guard layer.

Install

git clone [email protected]:SafeAI-Lab-X/ClawKeeper.git
cd ClawKeeper

python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"

Sanity check:

pytest -q

Use with Hermes Agent

from run_agent import AIAgent

from clawkeeper_core import Judge
from clawkeeper_core.adapters.hermes import install as install_clawkeeper

agent = AIAgent(...)
install_clawkeeper(Judge(), agent)

agent.run("your task")

This installs the default pre-tool guard chain and post-tool-result scanners. No Hermes patching is required.

Run the HTTP core

For hosts that cannot import the Python package directly:

clawkeeper-server
curl http://127.0.0.1:7474/v1/health

Useful endpoints include /v1/judge, /v1/event, /v1/audit, /v1/scan/logs, /v1/scan/skill, and maintenance harden/rollback routes.

Run the Watcher

The Watcher is optional. It is useful when single-command rules are not enough and the decision depends on intent, recent tool history, or multi-step drift.

export CK_WATCHER_API_KEY="$OPENAI_API_KEY"
export CK_WATCHER_BASE_URL="$OPENAI_BASE_URL"   # optional, OpenAI-compatible
export CK_WATCHER_MODEL="gpt-5.5"               # or your configured model

python -m clawkeeper_core.watcher.daemon
curl http://127.0.0.1:9099/watcher/health

Wire it into Hermes:

install_clawkeeper(
    Judge(),
    agent,
    watcher_url="http://127.0.0.1:9099",
)

Core guards

The default guard set currently covers:

• dangerous shell execution
• protected path access
• unsafe URL / SSRF patterns
• script-body and dynamic-path inspection
• base64/hex encoded payloads
• credential discovery plus network exfiltration chains
• poisoned return content
• credential redaction

The exact policies are intentionally small and inspectable; see clawkeeper_core/guards/.

Development

pip install -e ".[dev]"
pytest -q

Red-team fixtures and benchmark scripts live under tests/redteam/ and experiments/.
