AI agents call crud_query to retrieve information from OODA Computer Control without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation on a collection. It retrieves or queries data without side effects, which aligns with the Read category. Despite the server providing destructive and execute capabilities elsewhere (batch_delete_files, batch_exec_cli), this specific tool is limited to querying.
From the tool's definition Tool name 'crud_query' and description 'Query records in a collection' indicate a retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access crud_query 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_query:
{
"version": "1",
"default": "deny",
"tools": {
"crud_query": {}
}
}crud_query is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Query records in a collection. It is categorised as a Read tool in the OODA Computer Control MCP Server, which means it retrieves data without modifying state.
Register the OODA Computer Control MCP server in PolicyLayer and add a rule for crud_query: 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_query is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the crud_query 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_query. 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_query 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.
