Premiere Pro MCP Server

Open Project

open_project

Open a Premiere Pro project file (.prproj) and set it as active, verifying success while keeping other projects open.

Instructions

Open a Premiere Pro project file and make it the active project, verifying it is open. Other open projects stay open.

TDQS

A4/5.0
Behavior4/5

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

Annotations cover the safety profile (readOnly=false, destructive=false, idempotent=false), so the description's job is lighter. It usefully adds two behavioral facts beyond annotations: the operation verifies the project is open, and other open projects are left open (i.e., it is additive, not exclusive). It does not explain failure behavior when the path is invalid.

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?

A single front-loaded sentence delivering action, target, resulting state, and side-effect scope with zero filler.

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?

For a one-parameter mutation tool with full annotations and an output schema (so return values need not be described), the description covers action, result state, and side-effect scope. It stops short of addressing error/edge cases such as a missing or locked project file.

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?

Only one parameter with 100% schema description coverage ('Full file path to the .prproj file'), so the schema already carries the semantics. The description reinforces the .prproj file type but adds no new meaning such as path format or relative-path support.

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?

States a specific verb (Open) and resource (Premiere Pro project file), plus the resulting state change (becomes the active project). It is easily distinguished from siblings like close_project, create_project, and open_in_source.

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 it (loading a .prproj as the active project) but never explicitly names alternatives such as open_in_source or close_project, nor states prerequisites or when-not-to-use conditions. Usage is inferable but not spelled out.

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