Premiere Pro MCP Server

Get Last Operations

get_last_operations

Read-onlyIdempotent

Lists recent state-changing tool calls with status, outcome, and timing, newest first. Check it after a client-side timeout before retrying an edit, so a call still running or already succeeded is not sent twice.

Instructions

Read-only: list the most recent state-changing tool calls this MCP server process handled, newest first, with status (running, succeeded, failed), receipt outcome and timing. Use it after a client-side timeout before retrying an edit: a call still running, or one that already succeeded, must not be sent again. The running count includes all active calls, even outside the history window; runningOperations lists up to limit active calls and runningOperationsTruncated flags omitted entries. Entries made with idempotency_key carry idempotencyKeyHash, a 12-character SHA-256 prefix (never the raw key). Records only tool names, timing and outcomes; it does not prove Premiere state, and it starts empty when the server restarts.

Input Schema

Name	Required	Description
`limit`	No	How many operations to return, newest first (default 10, max 50).
`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.

Behavior5/5

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

Annotations already declare read-only, idempotent and non-destructive, yet the description still adds substantial context: records are per-process, start empty on restart, include only tool names/timing/outcomes, and do not prove Premiere state. It also explains the running count spans calls outside the history window, that runningOperationsTruncated flags omissions, and that idempotency key hashes are 12-character SHA-256 prefixes, never raw keys.

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?

Front-loaded with the read-only scope and the timeout/retry use case, then the edge-case details. Every sentence carries information, though the single dense block of caveats could be split for easier scanning.

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

Completeness5/5

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

An output schema covers return values, so the description only needed to explain scope, lifecycle (empty on restart), limits and trust boundaries — all of which it does. Nothing an agent needs to interpret the log is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds real semantics: the limit governs both history entries and the runningOperations list, and truncation is signaled explicitly. That is meaning beyond the schema's per-property descriptions.

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, resource and scope: list the most recent state-changing tool calls handled by this MCP server process, newest first, with status, receipt outcome and timing. This is clearly separable from siblings like inspect_operation_recovery or acknowledge_operation_recovery, which operate on recovery state rather than a live operation log.

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?

'Use it after a client-side timeout before retrying an edit' names a concrete trigger and the decision it drives (a running or succeeded call must not be resent). It stops short of naming the alternative recovery tools or saying when this log is not the right source, so it is clear guidance without exclusions.

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