AI agents call get_databar_text 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 'get_' prefix strongly suggests this tool retrieves data from the microscope's databar (likely metadata or status text) without modifying state. No side effects or write operations are implied.
From the tool's definition Tool name 'get_databar_text' indicates a getter/retrieval operation with no parameters specified in description. Consistent with sibling tools like 'get_beam_shift', 'get_brightness', 'get_contrast', 'get_detector' which are read-only queries.

get_databar_text. 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_databar_text: 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_databar_text 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_databar_text 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_databar_text. 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_databar_text 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.
