LeCroy Oscilloscope MCP

by lucasgerads

scope_set_trigger_delay

Adjust the horizontal position offset on a LeCroy oscilloscope by setting a trigger delay in seconds. Positive values shift the trigger point left; negative values shift it right.

Instructions

Set the trigger delay (horizontal position offset).

Args: seconds: Delay in seconds. Positive = trigger point moves left, negative = trigger point moves right.

Transport: SCPI

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description is responsible for disclosing behavioral traits. It only states that it sets a delay and mentions Transport: SCPI, but fails to describe side effects, required mode, or whether it is destructive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise, front-loaded, and well-structured with a clear purpose, argument list, and transport hint. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the low complexity and presence of an output schema, the description covers the parameter meaning but omits prerequisites, error conditions, and behavioral context. It is adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description compensates by explaining the 'seconds' parameter in detail, including sign convention (positive left, negative right). However, it lacks limits or allowed range.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb (Set) and the resource (trigger delay) with additional context (horizontal position offset), distinguishing it from siblings like scope_configure_trigger or scope_set_tdiv.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
