scope_configure · Oscilloscope MCP: Risk & Policy

WHAT IT DOES

What scope_configure does on Oscilloscope

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

WHY IT NEEDS A POLICY

Why scope_configure needs a policy

Based on the tool name 'scope_configure' and the server context of oscilloscope control, this tool most likely configures device settings (e.g., timebase, voltage range, channel settings). Configuration changes modify device state reversibly, placing it in the Write category. Confidence is reduced due to the empty description.

From the tool's definition Tool name 'scope_configure' on a server that controls USB oscilloscopes; description is empty and uninformative.

Verdict

scope_configure Rate-limited

scope_configure 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Oscilloscope, so you can run agents against it safely.

FAQ

Questions about scope_configure

What does the scope_configure tool do? +

scope_configure. It is categorised as a Write tool in the Oscilloscope MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on scope_configure? +

Register the Oscilloscope MCP server in PolicyLayer and add a rule for scope_configure: 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 Oscilloscope. Nothing to install.

What risk level is scope_configure? +

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

Can I rate-limit scope_configure? +

Yes. Add a rate_limit block to the scope_configure 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 scope_configure completely? +

Set action: deny in the PolicyLayer policy for scope_configure. 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 scope_configure? +

scope_configure is provided by the Oscilloscope MCP server (sandraschi/oscilloscope-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
