Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.05674 |
| Opus 5 | $0.00000 | $0.02837 |
| Sonnet 5 | $0.00000 | $0.01135 |
| Haiku 4.5 | $0.00000 | $0.00567 |
Grade A, and why
openclaw scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 918 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenClaw Integration
OpenClaw is an open-source AI agent framework that uses the Model Context Protocol (MCP) for tool integration. Bulwark integrates with OpenClaw via the MCP gateway to add governance, policy enforcement, and audit logging.
Overview
Bulwark provides OpenClaw with:
- Policy enforcement: Control which tools OpenClaw can use
- Credential management: Securely inject API keys and tokens
- Audit logging: Track all tool calls and decisions
- Content inspection: Scan for secrets, PII, and security issues
- Rate limiting: Control request rates and costs
- Governance metadata: Rich policy information in tool responses

MCP Servers (filesystem, github, slack, database, etc.)
OpenClaw connects to Bulwark's MCP gateway, which enforces policies and forwards approved requests to the configured MCP servers.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openclaw is an agent published in the GitHub repository claudius-ars/bulwark (4 stars, last pushed 6mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 5,674 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
