Premiere Pro MCP Server

Close Sequence

close_sequence
Destructive

Requests closing a sequence timeline tab in Premiere Pro, optionally by sequence name or ID; defaults to active sequence. The sequence stays in the project.

Instructions

Request closing a sequence timeline tab. Premiere exposes no open-tab enumeration, so dispatch is requested_unverified; the sequence stays in the project.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sequence_idNoSequence name or ID. Uses active sequence if omitted.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
okYesWhether the tool completed successfully.
dataNoTool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it.
toolYesThe registered MCP tool name.
errorNoFailure detail when ok is false.

TDQS

A4/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and non-idempotent, so the safety profile is partly covered. The description adds genuinely non-obvious context the annotations cannot carry: there is no open-tab enumeration in Premiere, so the dispatch is "requested_unverified," and the underlying sequence survives the close. That verification limitation is exactly the kind of behavioral caveat that changes how an agent should treat success/failure.

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?

Two sentences, zero padding, and the operation is front-loaded before the caveat. The dense phrasing ("dispatch is requested_unverified") is jargon but earns its place by conveying a real verification limit.

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 no explanation, and the tool is single-parameter and simple. The description covers the critical caveats (unverified dispatch, non-destructive to project data). It stops short of stating what happens when the target sequence is not open, which is the one remaining gap for an unverifiable operation.

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% and the single parameter's default ("Uses active sequence if omitted") is already documented in the schema. The description adds no additional meaning about sequence_id resolution or naming ambiguity, so the baseline 3 applies.

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 and resource ("Request closing a sequence timeline tab") and immediately scopes it against the natural confusion case with delete_sequence by noting "the sequence stays in the project." An agent can distinguish this from deletion or from close_project without opening the schema.

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 contrast with deletion is implied by "the sequence stays in the project," which is useful routing information. However, there is no explicit when-to-use statement, no mention of prerequisites (must the sequence be open/active?), and no named alternative among the many siblings such as delete_sequence or close_project. Usage is inferable but not stated.

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