AI agents call list_databases to retrieve information from OLEXI Australian Laws MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or enumerates metadata about available legal databases in AustLII, a read-only operation. No creation, modification, deletion, or execution occurs. The empty description lowers confidence slightly, but context from the server's purpose (searching legislation and case law) and sibling search tools strongly indicates this is a lookup/enumeration function.
From the tool's definition Tool name 'list_databases' with empty description; inferred from sibling tools (search_austlii, build_search_url) that this server provides read-only legal document retrieval. Listing available databases is a query operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_databases gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OLEXI Australian Laws MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_databases:
{
"version": "1",
"default": "deny",
"tools": {
"list_databases": {}
}
}list_databases is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the OLEXI Australian Laws MCP Server MCP server in PolicyLayer and add a rule for list_databases: 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 OLEXI Australian Laws MCP Server. Nothing to install.
list_databases 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 list_databases 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 list_databases. 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.
list_databases is provided by the OLEXI Australian Laws MCP Server MCP server (konashevich/olexi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
