AI agents call liara_list_releases to retrieve information from Liara MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves release information for an application without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation with no blast radius if misused by an AI agent, as it only returns existing information.
From the tool's definition Tool name 'liara_list_releases' and description 'List all releases for an app' indicate a retrieval operation with no side effects. The verb 'list' is explicitly a Read operation.
Documented attack patterns abuse exactly the kind of access liara_list_releases gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Liara MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for liara_list_releases:
{
"version": "1",
"default": "deny",
"tools": {
"liara_list_releases": {}
}
}liara_list_releases is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all releases for an app. It is categorised as a Read tool in the Liara MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Liara MCP Server MCP server in PolicyLayer and add a rule for liara_list_releases: 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 Liara MCP Server. Nothing to install.
liara_list_releases 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 liara_list_releases 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 liara_list_releases. 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.
liara_list_releases is provided by the Liara MCP Server MCP server (razavioo/liara-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Liara MCP Server, 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.
