Clawshell
Open-source OS-level runtime security that keeps real API keys and PII out of compromised OpenClaw and Hermes Agent processes.
If you run OpenClaw or Hermes Agent with real credentials in the environment, ClawShell addresses the exact attack its own demo reproduces — an injected instruction reading $OPENAI_API_KEY and walking out with it. Moving the key behind a Unix-permission boundary so the agent only ever holds clawshell-virtual://openai/**** is a structural fix, which is more than prompt-based guardrails can claim. Against alternatives: generic secret managers and vaults protect storage and injection, not the agent's runtime process space; LLM firewalls and DLP proxies inspect traffic but still leave a usable token in the agent's environment. ClawShell's cost is scope — it names OpenClaw and Hermes Agent, so

Skip ClawShell if your agents run on a framework other than OpenClaw or Hermes Agent, or if you need a central cloud console to manage policy across machines rather than editing local configuration on each host.
ClawShell is local-only, so running it across a fleet means building your own config-distribution and drift-detection tooling — an engineering cost, not a line item on a bill
The published plan is the open-source Apache 2.0 build at $0, with npm and cargo installs and no cloud dependencies. That makes the cost comparison less about license fees and more about engineering time: you pay in setup, host permissions and ongoing pattern tuning. Compare against hosted agent-security or LLM-firewall products, which charge per seat or per request but supply the dashboard and rule library you otherwise build yourself.

About Clawshell
ClawShell is an open-source runtime security layer for AI agents, positioned for OpenClaw, Hermes Agent "and beyond." It runs as a separate privileged process that holds your real API keys, DLP patterns, and credentials. Your agent never receives them — it holds only virtual identifiers such as clawshell-virtual://openai/****. When the agent makes a request, ClawShell scans it, injects the real token in the secure process, scans the response, and redacts PII before anything comes back. The boundary is enforced by Unix file permissions on /etc/clawshell, kernel-enforced user and capability controls, not by prompt instructions. Vendor copy states the point plainly: "Trying to enforce security inside a system vulnerable to manipulation is like asking untrusted code to enforce its own sandbox." A bundled attack-demo.sh shows the failure mode it targets — a multi-turn prompt injection that gzips ~/.config/secrets, renames it to a .png to slip past file filters, then echoes $OPENAI_API_KEY. Under ClawShell, that same echo returns only a virtual identifier. Install is npm install -g @clawshell/clawshell or cargo install clawshell --locked, then sudo clawshell onboard, which scans your agent config and environment variables, finds keys like OPENAI_KEY and ANTHROPIC_KEY, migrates them into ClawShell's protected configuration, and replaces the originals with virtual identifiers. Existing skills and workflows need no modification. Everything is local — no cloud dependencies and no hardware security modules. It is built in Rust on Tokio, ships under Apache 2.0, and the vendor claims a memory footprint under 10MB. It is aimed at developers and security engineers running agent automation where secrets handling falls under GDPR, HIPAA, or SOC 2, and it is a narrow tool: the public material names OpenClaw and Hermes Agent, not other frameworks.
Behind the Verdict
The idea worth stealing here is the split. Most agent security tries to make the untrusted thing trustworthy — better system prompts, input filters, output classifiers. ClawShell instead accepts that the agent process will eventually be compromised and removes the prize. Secrets live under /etc/clawshell behind Unix file permissions; the agent holds virtual keys; ClawShell injects the real token on the way out and DLP-scans on the way back. The vendor frames this with Simon Willison's "Lethal Trifecta" — private data, untrusted input, external communication — and breaks the first leg rather than trying to police the other two. The attack-demo.sh walkthrough is the most convincing part of the pitch: gzip the secrets directory, rename the archive to .png to slip past extension-based file filters, echo the API key. That renaming step is exactly the kind of thing naive output filtering misses, and it is why an OS boundary beats a pattern list. Second strength: onboarding is genuinely small. sudo clawshell onboard scans configuration and environment variables, identifies keys like OPENAI_KEY and ANTHROPIC_KEY, migrates them, and rewrites the originals as virtual identifiers, with no changes to existing skills or workflows. Rust plus Tokio, Apache 2.0, no cloud dependency, no HSM — the whole thing is auditable and runs on the box. The honest weaknesses are scope and maturity. The homepage headline says "OpenClaw, Hermes Agent, and beyond," but the only frameworks named anywhere in the material are those two, so treat "beyond" as a stated intention, not a supported list. Everything is local, which is the design — but it means no team dashboard and no central policy console, so consistent configuration across a fleet is your problem to solve with your own tooling. The project leans on third-party statistics (Wiz on leaked API keys, Snyk on skill vulnerabilities and the ToxicSkills payload count) rather than on published independent testing of ClawShell itself, so the evidence for the tool is architectural and demonstrative, not benchmarked. Maintenance status, docs depth, and release activity are things to verify yourself before this carries production credentials. Where it fits: teams already committed to OpenClaw or Hermes Agent who can accept local-only policy management. Where it does not: anyone on a different agent framework, anyone who needs a central console, and anyone without command-line comfort — onboard is a sudo command, not a toggle.

Real-world workflow fit
Concrete scenarios for the personas Clawshell actually fits — and what changes day-one when you adopt it.
Runs npm install -g @clawshell/clawshell then sudo clawshell onboard, which scans the agent's configuration and environment, finds OPENAI_KEY and ANTHROPIC_KEY, migrates them into ClawShell's protected configuration, and replaces the originals with virtual identifiers
Outcome: The agent now holds only clawshell-virtual://openai/****, so a successful prompt injection yields a token that resolves to nothing outside the privileged process
Executes the bundled attack-demo.sh against an unprotected agent — gzip ~/.config/secrets, rename the archive to backup.png, then echo $OPENAI_API_KEY — and repeats it after onboarding
Outcome: The first run prints a live-looking sk-proj- key and reports successful exfiltration; the second run returns only a virtual identifier, giving the team a repeatable before/after artifact for review
Points agents at ClawShell so requests and responses pass through the DLP scan and token-mapping step in the privileged process overnight, then inspects local configuration for what is allow-listed
Outcome: Sensitive values are redacted before they land in logs and storage, and the documented boundary — Unix permissions on /etc/clawshell — is what gets shown to auditors
Use Cases
- Stop an injected instruction from reading and exfiltrating $OPENAI_API_KEY or $ANTHROPIC_KEY
- Redact PII from agent responses before they reach chat logs or storage
- Give agent processes virtual keys so a full compromise yields no usable credential
- Keep API credentials inside a privileged process under Unix file permissions rather than in the agent environment
- Run agent automation on-prem with no cloud dependency or hardware security module
- Reproduce prompt-injection exfiltration with attack-demo.sh and verify the same attack fails under ClawShell
- Migrate existing OpenClaw or Hermes Agent key configuration without rewriting skills or workflows
- Satisfy GDPR, HIPAA, or SOC 2 data-handling expectations for agent workflows that touch real credentials
Limitations
- Narrowly scoped.
- The public material names OpenClaw and Hermes Agent as the supported frameworks; "and beyond" on the homepage is an intention, not a documented support list, so verify your framework before investing.
- Configuration and policy are entirely local — there is no cloud-based management or team dashboard, so keeping policy consistent across many machines falls to your own tooling.
- Onboarding requires a sudo command, so setup assumes command-line proficiency and a Unix-like host.
- The evidence published for the tool is architectural and demo-based (attack-demo.sh) plus third-party statistics from Wiz and Snyk about agent security generally, not independent benchmarking of ClawShell itself.
- The material carries no information about the project's maintenance status, release cadence, or documentation depth — check the GitHub repository's activity before putting it in front of production credentials.

Setup time & first value
How long it actually takes to get something useful out of Clawshell — broken out by persona, not the marketing-page minute.
Install and onboarding are quoted at under a minute: one npm or cargo command followed by sudo clawshell onboard, which scans configuration and environment variables, migrates keys and writes virtual identifiers back. Existing skills and workflows need no modification, so time to first value is the install itself. Budget additional time afterwards for reviewing DLP patterns, tightening Unix
Switching to or from Clawshell
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From raw API keys in the agent environment: sudo clawshell onboard scans config and env vars, migrates OPENAI_KEY and ANTHROPIC_KEY into ClawShell's protected configuration, and replaces each original with a virtual
- →From prompt-based guardrail instructions: drop the instruction-level restrictions and let Unix permissions on /etc/clawshell plus the request/response DLP scan carry the boundary, leaving skills and workflows unchanged
- ↗To plain environment-variable secrets: restore the originals from ClawShell's protected configuration and remove the privileged process and its permission boundary
- ↗To a hosted agent-security or LLM-firewall product: map your ClawShell DLP patterns into the vendor's rule set and confirm whether their proxy can also inject real tokens on the outbound side
