Get Clip Properties

get_clip_properties
Read-onlyIdempotent

Retrieve detailed properties of a specific clip by its node ID to inspect media attributes, timing, and track information.

Instructions

Get detailed properties of a specific clip by its node ID

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "node_id": "<node_id>"
    },
    "name": "get_clip_properties"
  }
}

Input Schema

NameRequiredDescriptionDefault
node_idYesThe node ID of the clip
expected_cep_targetNoOptional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard.
expected_project_pathNoOptional 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

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.
receiptNoVersioned common mutation receipt; success never implies rendered verification.
idempotencyNoPresent when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again.

C2.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing about how the optional expected_cep_target / expected_project_path guards behave (that a mismatch causes refusal) or what the call returns, even though these guard semantics are behaviorally significant and not obvious from the annotation set.

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?

One short sentence, front-loaded with verb and resource, with no filler. It is arguably too terse rather than wasteful, so it earns credit for economy rather than penalty for padding.

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?

The tool is simple and read-only, it has an output schema, and all three parameters are fully described in the schema, so most of what an agent needs is elsewhere. Still, in a family with many overlapping clip/property getters, the description would benefit from one clause stating the differentiator and when the guard parameters matter.

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 nested guard objects are documented in detail in the schema, so the description need not repeat them. The single sentence only restates that the lookup is keyed by node_id, adding no syntax or sourcing hints 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 ('Get detailed properties of a specific clip') plus the lookup key (node ID), so the intent is unambiguous. However, it does not distinguish itself from nearby siblings such as get_full_clip_info, get_qe_clip_info, or get_item_info, which an agent must choose between.

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?

No guidance on when to use this versus get_full_clip_info or get_qe_clip_info, both of which appear to return clip data. There is also no mention of prerequisites (e.g., that node_id must come from a prior lookup) or when the optional guard parameters should be supplied.

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