Premiere Pro MCP Server

Get Target Tracks

get_target_tracks

Read-onlyIdempotent

Retrieve all video and audio tracks currently targeted for editing in Premiere Pro, including unreadable tracks, so you can confirm edit targets before making changes.

Instructions

Get which tracks are currently targeted for editing. Premiere allows several video or audio tracks to be targeted at the same time; every targeted track is listed. Tracks whose state cannot be read are listed under unreadable.

Input Schema

Name	Required	Description	Default
`expected_cep_target`	No	Optional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard.
`expected_project_path`	No	Optional absolute saved-project path. Every generated CEP command refuses before its body when the active project differs or is unsaved. UXP commands refuse this CEP-only guard; local-only tools do not inspect Premiere. Omit to keep existing behavior.

Output Schema

Name	Required	Description
`ok`	Yes	Whether the tool completed successfully.
`data`	No	Tool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it.
`tool`	Yes	The registered MCP tool name.
`error`	No	Failure detail when ok is false.
`receipt`	No	Versioned common mutation receipt; success never implies rendered verification.
`idempotency`	No	Present when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again.

TDQS

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds genuine value by disclosing that multiple tracks may be targeted and that unreadable states are surfaced in a separate bucket rather than erroring. It does not say what happens when no sequence is active or how partial read failures affect the rest of the result.

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?

Three short sentences, front-loaded with the core answer, followed by the multi-target semantics and the unreadable-state caveat. No filler and nothing buried.

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 read-only query with full annotations and an output schema, the description covers purpose and result shape adequately. The remaining gap is scope: it never says the tracks come from the active sequence, which the agent must know to interpret the result.

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?

Both parameters are optional guard parameters (expected_cep_target, expected_project_path) with 100% schema description coverage, so the schema does the work. The description never mentions them or explains when the guard is useful, so it adds nothing beyond the schema; 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 and resource: retrieving which tracks are currently targeted for editing. It also explains the multi-target semantics of Premiere and the 'unreadable' bucket, which no sibling duplicates. It stops short of explicitly distinguishing itself from neighbors like list_sequence_tracks or get_track_info.

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?

Usage is only implied: an agent can infer this is the read-side counterpart to set_target_track / set_all_tracks_targeted. There is no explicit when-to-use, no mention of the alternative tools, and no statement of prerequisites (e.g. that an active sequence must exist).

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