Premiere Pro MCP Server

Set Clip Rotation

set_clip_rotation

Set the rotation of a video clip's Motion effect in Premiere Pro by providing the clip ID and degrees, then verify the applied value.

Instructions

Set the Rotation property on a video clip's Motion effect using English or measured Spanish built-in names, then read it back.

TDQS

B3.2/5.0
Behavior3/5

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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false), so the behavior is largely covered structurally. The description usefully discloses that the value is read back after setting, but it does not explain the surprising idempotentHint=false, required permissions, or the dependency on a Motion effect existing.

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

Conciseness4/5

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

A single front-loaded sentence with the verb first. It is appropriately sized, though the middle 'English or measured Spanish built-in names' fragment is confusing filler that does not clearly earn its place.

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

Completeness4/5

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

An output schema exists, so return values need not be explained, and both parameters are documented in the schema. The only residual gap is the unexplained reference to a Motion effect and the non-idempotent annotation, which for a simple setter is minor.

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

Parameters3/5

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

Schema description coverage is 100%, so both node_id and degrees are already documented with type and range context. The description adds nothing about the parameters themselves, merely referencing the effect property naming, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb (Set) and resource (the Rotation property on a clip's Motion effect), which distinguishes it from siblings like set_clip_scale, set_clip_opacity, and set_clip_position. The core action is unambiguous, though the 'English or measured Spanish built-in names' clause is odd and slightly muddies the intent.

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?

There is no when-to-use or when-not-to-use guidance, and no alternative tool is named. Nothing tells the agent when rotation-setting is the right choice versus the many other clip-property tools.

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