Add To Render Queue

add_to_render_queue

Queue the active sequence for Adobe Media Encoder rendering using a saved project and .epr preset. Optionally start the entire ready AME queue; Premiere-hosted presets are refused before contact.

Instructions

Request an Adobe Media Encoder render-queue handoff for the active sequence. Requires a saved project and an .epr preset_path. Same as Project presets are refused before Premiere is contacted because AME encodes from a scratch project copy. Optional start_batch requests processing of every ready AME queue job, including unrelated jobs.

Tool call template

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

Input Schema

NameRequiredDescriptionDefault
output_pathYesFull output file path
preset_pathYesRequired path to an AME preset file (.epr). Omitting this raises an Illegal Parameter error on current Premiere hosts.
start_batchNoOpt in to start the entire ready Adobe Media Encoder queue after this handoff, including unrelated jobs. Default false (enqueue only). A successful call does not verify that any render started or completed.
idempotency_keyNoOptional client-chosen key (1-128 chars of A-Z a-z 0-9 . _ : -) for this intended edit. Pass a fresh key per edit and reuse it only when retrying that same edit, for example after a client-side timeout. A repeat with the same tool, key and arguments is not run again: while the first call is running it fails with IDEMPOTENCY_IN_PROGRESS (poll get_last_operations); after it finished it returns the original outcome marked replayed. A definite failure with nothing applied (receipt outcome not_applied) may be retried with the same key. Reusing a key with different arguments fails with IDEMPOTENCY_KEY_REUSED. Scoped to this MCP session (the stdio server process, or the HTTP server process when Streamable HTTP is stateless per request) and held in memory only (200 keys, 1 hour); it does not survive a restart or reconnect. Read-only invocations are never deduplicated.
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.

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare the non-readOnly, non-destructive, non-idempotent profile, and the description adds real context: same-as-project presets are refused before Premiere is contacted because AME encodes from a scratch project copy, and start_batch can start unrelated queue jobs. However, the key sentence is garbled ('Same as Project presets are refused...'), obscuring the exact refusal rule, and there is no statement about what handoff artifact is produced beyond the output schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Prerequisites are front-loaded effectively, but the sentence 'Same as Project presets are refused before Premiere is contacted' is a broken fragment that costs clarity without adding content. Two of four sentences are high value; one is malformed.

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 6-parameter tool with nested CEP guards and an output schema, the description covers the critical operational facts: saved-project requirement, mandatory .epr preset, pre-contact refusal, and the blast radius of start_batch. The grammar break in the preset-refusal sentence is the main residual gap.

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%, so the schema already documents output_path, preset_path (.epr), start_batch, idempotency_key, and the expected_* guards. The description adds only the note that start_batch may start unrelated AME jobs, which the schema also states. Baseline 3 is appropriate.

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?

Names a concrete verb and resource: request an Adobe Media Encoder render-queue handoff for the active sequence. The AME/encoder framing implicitly separates it from the After Effects handoff siblings, but it never names an alternative tool or contrasts its scope explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

States prerequisites clearly (saved project, an .epr preset_path) and flags the start_batch opt-in behavior, including that it processes unrelated ready jobs. It lacks explicit 'use this instead when...' routing versus get_render_queue_status or the After Effects equivalents.

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