openclaw-tool-audit 0.1.3

Audit OpenClaw allowed tools against observed tool usage.

openclaw-tool-audit

openclaw-tool-audit is a small CLI for reviewing OpenClaw tool permissions against actual local tool usage. It is intentionally focused on permission-versus-usage visibility for security reviews.

Install

pipx install openclaw-tool-audit
brew install pfrederiksen/tap/openclaw-tool-audit

From a checkout:

python -m pip install -e .
openclaw-tool-audit --help

Examples

openclaw-tool-audit
openclaw-tool-audit --agent main --last 14d
openclaw-tool-audit --json
openclaw-tool-audit --markdown --broadest-first
openclaw-tool-audit --config fixtures/agents --sessions fixtures/sessions --top-tools 5
openclaw-tool-audit --version

By default the CLI checks these config locations:

• ./.openclaw/agents
• ./agents
• ~/.openclaw/agents

And these observed session locations:

• ./.openclaw/sessions
• ./sessions
• ~/.openclaw/sessions
• ~/.openclaw/transcripts
• ~/.openclaw/agents/<agentId>/sessions

Use --config PATH and --sessions PATH to point at specific files or directories. Both flags may be repeated.

Where Allowed Tools Come From

Allowed tools are read from local agent configuration files. The CLI supports .json, .toml, .yaml, and .yml files.

It looks for common allowlist fields at any depth:

• allowed_tools
• tools
• tool_allowlist
• allow_tools
• allowedToolNames
• allowed_tools_list

Values may be a list of strings, a comma/space separated string, a list of objects with name, tool, or id, or a mapping where enabled tools are marked true, allow, allowed, or enabled.

Where Observed Tools Come From

Observed tools are read from local session or transcript files. The CLI supports .json, .jsonl, .ndjson, .txt, .md, and .log.

Structured JSON scanning recognizes common tool-call shapes:

• {"type": "tool_call", "name": "read_file"}
• {"type": "tool_use", "tool": "web"}
• {"type": "tool", "tool": {"name": "shell"}}
• {"type": "input_tool_call", "name": "read"}
• {"type": "tool_use", "toolName": "edit"}
• {"recipient_name": "functions.exec_command"}
• {"function": {"name": "fetch_url"}}
• {"function_call": {"name": "summarize"}}
• {"functionCall": {"name": "web_fetch"}}
• {"message": {"tool_calls": [{"function": {"name": "exec"}}]}}
• {"message": {"content": [{"type": "input_tool_call", "name": "read"}]}}

Plain text transcripts are scanned with conservative patterns such as to=tool_name, recipient_name, and <tool>tool_name</tool>.

When session records do not include agent metadata, files under ~/.openclaw/agents/<agentId>/sessions are attributed to <agentId>. Explicit event-level agent metadata takes precedence over path inference.

Output

Terminal output includes:

• allowed tools
• observed tools and invocation counts
• unused allowed tools
• observed-but-not-allowed tools
• tools used most often
• suspicious broad allowances
• cron/job summaries when job names are present in transcripts

Suspicious broad allowances are heuristics. The CLI flags wildcard-like tools, broad capability tokens such as shell, filesystem, network, web, and github, and allowlists where most entries were not observed.

Options

--agent NAME       Only show one agent.
--last 14d         Filter observations by transcript file mtime. Supports h, d, and w.
--json             Emit JSON.
--markdown         Emit Markdown.
--top-tools N      Limit observed tool lists to the top N.
--unused-only      Only show agents with unused allowed tools.
--broadest-first   Sort agents by broad allowance signals first.

Development

python -m pip install -e ".[dev]"
pytest

This project has no runtime dependencies. YAML support uses PyYAML when available and otherwise falls back to a small parser that handles simple key/value and list allowlists.

Release

Releases are tag-driven. Create a version tag such as:

git tag v0.1.0
git push origin v0.1.0

The release workflow builds the package, publishes to PyPI, creates a GitHub release, and bumps the Homebrew formula in pfrederiksen/homebrew-tap.

Required repository secrets:

• HOMEBREW_TAP_TOKEN, a GitHub token that can push to pfrederiksen/homebrew-tap.

For PyPI, either configure Trusted Publishing for this repository or set PYPI_API_TOKEN as a repository secret.

Do not commit PyPI tokens to the repository.

Limitations

• OpenClaw config and transcript formats are inferred from common local shapes; unusual schemas may need explicit --config and --sessions paths or parser updates.
• --last currently filters by transcript file modification time, not by event-level timestamps.
• Text transcript parsing is best effort and may miss custom tool-call formats.
• The audit is visibility-focused; it does not enforce permissions or block tool usage.
