Premiere Pro MCP Server

List Sequence Tracks

list_sequence_tracks

Read-onlyIdempotent

List all video and audio tracks in a Premiere Pro sequence to inspect structure, track indices, and contents; uses the active sequence when no sequence ID is given.

Instructions

List all tracks (video and audio) in a sequence

Input Schema

Name	Required	Description
`sequence_id`	No	Sequence ID or name. Uses active sequence if omitted.
`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

B3.2/5.0

Behavior3/5

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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered and the description does not contradict it. The description adds no further behavioral context (e.g. that it enumerates both track groups in index order, or how tracks are identified), leaving it at the baseline for an annotated read-only tool.

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 no filler or redundancy. It is efficient, though partly because it omits anything beyond the bare action, so brevity here is borderline under-specification rather than tight authoring.

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

Completeness3/5

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

With an output schema present and full annotation coverage, the thin description is mostly sufficient for a read-only list call. However, for a tool whose schema carries nested optional identity guards (expected_cep_target, expected_project_path), a word about when those matter and what the listing contains would make it complete.

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%, including the nested expected_cep_target and expected_project_path guard parameters, so the schema does the heavy lifting. The description mentions no parameter semantics at all, which is acceptable at high coverage but adds zero value over the schema.

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 ('List all tracks (video and audio) in a sequence'), which is unambiguous about what is returned. It does not, however, differentiate from nearby siblings such as get_sequence_structure, get_track_info, or get_timeline_summary, so an agent cannot route between them on this text alone.

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?

The description offers no when-to-use guidance, no prerequisites, and no named alternatives. The only scoping hint (falling back to the active sequence when sequence_id is omitted) lives in the schema, not the description.

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