WHAT IT DOES

What configure_math_channel does on PicoScope MCP Server

AI agents use configure_math_channel to create or update resources in PicoScope MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PicoScope MCP Server environment.

WHY IT NEEDS A POLICY

Why configure_math_channel needs a policy

This tool modifies oscilloscope channel configuration for mathematical operations on signals, which is a Write operation—it changes device settings but does not delete data, execute arbitrary code, move money, or trigger irreversible actions. Severity is medium because misconfiguration could affect signal acquisition accuracy and analysis, but the effects are reversible by reconfiguring or reconnecting the device.

From the tool's definition Tool name 'configure_math_channel' and description 'Configure a math channel (channel operations)' indicate modification of oscilloscope channel settings. The verb 'configure' combined with 'math channel' suggests altering device state reversibly.

Verdict

configure_math_channel Rate-limited

configure_math_channel stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about configure_math_channel

What does the configure_math_channel tool do? +

Configure a math channel (channel operations). It is categorised as a Write tool in the PicoScope MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on configure_math_channel? +

Register the PicoScope MCP Server MCP server in PolicyLayer and add a rule for configure_math_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 PicoScope MCP Server. Nothing to install.

What risk level is configure_math_channel? +

configure_math_channel is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit configure_math_channel? +

Yes. Add a rate_limit block to the configure_math_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.

How do I block configure_math_channel completely? +

Set action: deny in the PolicyLayer policy for configure_math_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.

What MCP server provides configure_math_channel? +

configure_math_channel 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.
