AI agents call spectate to retrieve information from Scopa without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves and displays game history. It has no side effects, cannot modify game state, and poses minimal risk if misused by an AI agent. The low severity reflects that viewing past plays in a card game context cannot cause harm.
From the tool's definition Tool 'spectate' shows the full list of plays made so far in the game—a query operation that retrieves historical game state without creating, modifying, deleting, or executing any actions.
Attacks that exploit this kind of access
Show the full list of plays made so far in the game. It is categorised as a Read tool in the Scopa MCP Server, which means it retrieves data without modifying state.
Register the Scopa MCP server in PolicyLayer and add a rule for spectate: 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 Scopa. Nothing to install.
spectate 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 spectate 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 spectate. 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.
spectate is provided by the Scopa MCP server (seboostian02/scopa-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
