Query the configuration of an analog channel. Returns volts/div, offset, coupling, bandwidth limit, trace on/off, probe attenuation, and unit.
AI agents call get_channel to retrieve information from Siglent Sds without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves oscilloscope channel configuration data without creating, modifying, deleting, or executing operations. It is purely informational and has no side effects beyond reading instrument state.
From the tool's definition Tool description states it 'Query[s] the configuration' and 'Returns' channel settings (volts/div, offset, coupling, bandwidth limit, trace on/off, probe attenuation, and unit). The verb 'query' and return-only nature indicate no modifications.
Attacks that exploit this kind of access
Query the configuration of an analog channel. Returns volts/div, offset, coupling, bandwidth limit, trace on/off, probe attenuation, and unit. It is categorised as a Read tool in the Siglent Sds MCP Server, which means it retrieves data without modifying state.
Register the Siglent Sds MCP server in PolicyLayer and add a rule for get_channel: 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 Siglent Sds. Nothing to install.
get_channel 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_channel 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_channel. 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_channel is provided by the Siglent Sds MCP server (magnusjohansson/siglent-sds-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
