AI agents call get_oplock_state to retrieve information from mcpXL30 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve the operational lock state of the microscope without modifying any parameters or triggering physical operations. This is a query operation consistent with other sibling 'get_' tools (get_beam_shift, get_brightness, get_contrast).
From the tool's definition Tool name 'get_oplock_state' indicates a state query operation. The 'get_' prefix and '_state' suffix are consistent with read-only retrieval of operational lock status. Description is empty, limiting certainty.
Attacks that exploit this kind of access
get_oplock_state. It is categorised as a Read tool in the mcpXL30 MCP Server, which means it retrieves data without modifying state.
Register the mcpXL30 MCP server in PolicyLayer and add a rule for get_oplock_state: 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 mcpXL30. Nothing to install.
get_oplock_state 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_oplock_state 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_oplock_state. 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_oplock_state is provided by the mcpXL30 MCP server (tspspi/mcpxl30). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
