What crestodian does on OpenClaw
AI agents invoke crestodian to trigger actions in OpenClaw. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why crestodian is rated High
The tool opens an interactive assistant for setup and repair, which suggests it can execute system-level configuration changes or repairs. This goes beyond a simple read operation. However, the description is vague, so confidence is moderate. The most applicable category is Execute due to the potential for triggering external operations or system changes via the assistant.
From the tool's definition 'Open the interactive setup and repair assistant' — 'setup and repair' implies triggering system configuration or repair operations
Attacks that exploit this kind of access
The rule that runs crestodian safely
PolicyLayer is an MCP gateway: it sits between your AI agents and OpenClaw, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crestodian, this is the rule to start with:
crestodian stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect OpenClaw, apply this rule, and every crestodian call is checked against it from then on.
Questions about crestodian
Open the interactive setup and repair assistant. It is categorised as a Execute tool in the OpenClaw MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the OpenClaw MCP server in PolicyLayer and add a rule for crestodian: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches OpenClaw. Nothing to install.
crestodian is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the crestodian rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for crestodian. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
crestodian is provided by the OpenClaw MCP server (openclaw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
