Premiere Pro MCP Server

Play Timeline

play_timeline

Starts playback of the active sequence timeline in Premiere Pro. Playhead movement remains unverified due to API limitations.

Instructions

Request playback of the active sequence timeline through QE. The legacy API does not provide a same-call playhead readback, so movement is not reported as verified.

A4.3/5.0

Behavior4/5

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

The annotations already flag this as non-read-only and non-idempotent, and the description adds meaningful behavioral context: the legacy API does not provide same-call playhead readback, so movement is not reported as verified. This is useful beyond the structured annotations and helps set expectations about verification.

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 two sentences with no filler. The primary action is front-loaded, and the verification caveat is placed immediately after. Every sentence contributes useful information.

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

Completeness5/5

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

With zero parameters and an output schema present, the description is sufficient for an agent to invoke the tool correctly. It also explicitly discloses the key limitation around playback verification, which is the main behavioral uncertainty. No critical context is missing.

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?

The tool has zero parameters, so there is no parameter semantics burden on the description. The schema is empty and description coverage is 100%, making additional parameter explanation unnecessary.

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 states a specific verb ('Request playback') and a specific resource ('the active sequence timeline through QE'), which clearly distinguishes it from sibling tools like play_source_monitor. The resource and mechanism are precise enough for an agent to identify what this tool does.

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

Usage Guidelines3/5

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

The description implies when to use this tool: when playback of the active sequence timeline is needed. However, it does not explicitly contrast it with alternatives such as play_source_monitor or stop_playback, nor does it state any conditions for preferring this tool over siblings.

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