AI agents call get_activities to retrieve information from Plex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve activity information from the Plex server—likely viewing history, currently playing media, or system activities. No modification, deletion, or financial operation is possible. The 'get_' prefix and read-only server design confirm it as a Read operation with low risk. Low confidence deduction due to empty description, but the broader context strongly supports this classification.
From the tool's definition Tool name 'get_activities' combined with server's stated purpose of 'read-only' access to Plex instance. Sibling tools like 'get_active_sessions', 'get_actors', 'get_genres' all retrieve data without modification.
Attacks that exploit this kind of access
get_activities. It is categorised as a Read tool in the Plex MCP Server, which means it retrieves data without modifying state.
Register the Plex MCP server in PolicyLayer and add a rule for get_activities: 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 Plex. Nothing to install.
get_activities 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 get_activities 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 get_activities. 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.
get_activities is provided by the Plex MCP server (x10send/plex-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
