List all saved authentication sessions/cookies.
AI agents call list_saved_sessions to retrieve information from WebClone MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates sensitive authentication sessions and cookies. While it is a Read operation (no data modification), the severity is elevated to 'high' because: (1) it exposes authentication credentials and session tokens that could be exfiltrated by a compromised agent, enabling account takeover or privilege escalation; (2) the blast radius includes all saved sessions across potentially multiple…
From the tool's definition Tool name 'list_saved_sessions' and description 'List all saved authentication sessions/cookies' indicate retrieval of stored credential data without modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and WebClone MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_saved_sessions:
{
"version": "1",
"default": "deny",
"tools": {
"list_saved_sessions": {}
}
}list_saved_sessions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all saved authentication sessions/cookies. It is categorised as a Read tool in the WebClone MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WebClone MCP Server MCP server in PolicyLayer and add a rule for list_saved_sessions: 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 WebClone MCP Server. Nothing to install.
list_saved_sessions 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_saved_sessions 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_saved_sessions. 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_saved_sessions is provided by the WebClone MCP Server MCP server (ruslanmv/webclone). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WebClone MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
