AI agents use crud_update to create or update resources in OODA Computer Control — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OODA Computer Control environment.
CRUD 'update' operations create or modify data reversibly without deletion or destruction. While the broader server context includes destructive operations (batch_delete_files) and execute capabilities (batch_exec_cli), this specific tool is limited to updating records.
From the tool's definition Tool name 'crud_update' and description 'Update an existing record' indicate reversible data modification.
Documented attack patterns abuse exactly the kind of access crud_update gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OODA Computer Control, and nothing reaches the server without passing your rules. This is the rule we recommend for crud_update:
{
"version": "1",
"default": "deny",
"tools": {
"crud_update": {
"limits": [
{
"counter": "crud_update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}crud_update stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Update an existing record. It is categorised as a Write tool in the OODA Computer Control MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the OODA Computer Control MCP server in PolicyLayer and add a rule for crud_update: 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 OODA Computer Control. Nothing to install.
crud_update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the crud_update 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 crud_update. 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.
crud_update is provided by the OODA Computer Control MCP server (mnehmos/mnehmos.ooda.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OODA Computer Control, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
