Get latest streaming data.
AI agents call get_streaming_data to retrieve information from PicoScope 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 or queries current streaming data from a PicoScope oscilloscope without creating, modifying, deleting, or executing arbitrary operations. It is a passive read operation with no side effects on the instrument or data. The blast radius is minimal—an agent cannot cause harm by reading oscilloscope measurements.
From the tool's definition Tool name is 'get_streaming_data' and description states 'Get latest streaming data.' The verb 'Get' and the read-only operation of retrieving live sensor data without modification indicate a data retrieval operation.
Attacks that exploit this kind of access
Get latest streaming data. It is categorised as a Read tool in the PicoScope MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PicoScope MCP Server MCP server in PolicyLayer and add a rule for get_streaming_data: 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 PicoScope MCP Server. Nothing to install.
get_streaming_data 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_streaming_data 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_streaming_data. 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_streaming_data is provided by the PicoScope MCP Server MCP server (markuskreitzer/picoscope_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
