What's new in premiere-pro-mcp—from editing tools and connector upgrades to reliability fixes.

Latest release

v1.14.9

v1.14.9

Latest

Guarded After Effects MOGRT studio and assistant workflows

Added

  • An optional, separate After Effects CEP connector can author five approval-gated title, callout, quote, and social Motion Graphics Template recipes in an already saved, workspace-contained project.
  • The studio adds brand-kit constraints, bounded JSON/CSV batches, immutable local template libraries, source inspection, queue-only renders, and explicit Premiere handoff verification.
  • Capability-aware assistant-editor workflows and GPT-6 Astra guidance help compatible clients inspect the authorized tool surface before proposing a workflow.

Changed

  • The MCP transport now applies bounded bridge-command backlog limits, and the public registry metadata and machine-readable references match the expanded tool surface.

Safety

  • The authoring path does not accept arbitrary scripts, create or switch projects, create output folders, overwrite artifacts, start renders, or claim that host acceptance, archive presence, or import descriptors are visual proof.
  • Capability discovery does not grant authority or turn a catalog, host acceptance, archive presence, or import descriptor into playback, render, or visual proof.

v1.14.8

Guarded After Effects MOGRT authoring and safer updates

Added

  • An optional, separate After Effects CEP connector can author one approval-gated lower-third Motion Graphics Template in an already saved, workspace-contained project.
  • The workflow includes a one-time preview token, explicit export confirmation, isolated local bridge channel, and local ZIP-header artifact check.
  • Caption timing review plans, revision-bound editorial evidence import, a no-write doctor repair-plan preview, and inspectable public workflow materials add bounded local guidance.

Changed

  • Global npm installations can use the Windows CEP panel to review the server and connector update state, then explicitly hand off the published-package update after Premiere closes. It does not force-close Premiere or alter projects, client configuration, source checkouts, or custom npm-prefix installs.
  • Stateless MCP construction reuses immutable descriptors and schemas while retaining isolated context, telemetry, and UXP state. Concurrent CEP commands share a response-directory watcher with polling retained as the correctness fallback.
  • The public landing uses a lighter mobile-first workflow treatment, explicit reduced-motion behavior, and current facts, structured data, sitemap, crawl policy, and machine-readable references for public pages.

Safety

  • The authoring path does not accept arbitrary scripts, create or switch projects, create output folders, overwrite artifacts, or claim that host acceptance or archive presence is import, rendered-frame, or visual proof.
  • Local timing plans, editorial evidence, repair plans, and public workflow materials remain separate from licensed-host, playback, rendered-output, provider, and marketplace verification.
View release

v1.14.7

Desktop protocol fallback and bounded UXP inspection

Added

  • Compatible UXP hosts gain bounded source-proxy readiness inspection with an explicit attached-path opt-in, plus read-only animated PointF endpoint-displacement inspection.

Fixed

  • Desktop clients can explicitly select the legacy stdio protocol when modern negotiation is unavailable; automatic mode remains the default and invalid configuration fails fast.
  • Updated affected dependency paths for @humanfs/node, fast-uri, and qs.
View release

v1.14.6

Guarded UXP editing and local review evidence

Added

  • Compatible UXP hosts gain guarded sequence range and playhead control, marker batch removal, native video transitions, caption inventory, silence-cut stringouts, and atomic split edits.
  • Local review workflows add delivery conformance, sampled media analysis, Warp Stabilizer status, shot-match planning, and revision-aware editorial context packs.
  • The release records UXP, CEP, ExtendScript, and native SDK integration surfaces with source-backed inventories.

Safety

  • Unsupported sequence pixel-aspect ratios, incomplete delivery probes, and partial transition writes fail closed. Mutations without a complete Adobe readback retain their documented verified or committed-unverified outcome; automated contracts remain distinct from licensed-Premiere host proof.
View release

v1.14.5

Verified mutation and playback hotfixes

Fixed

  • QE razor operations now pass sequence timecode instead of ticks, with regression coverage for split and all-track cuts.
  • Batch effect application preflights every target, resolves QE clips without assuming gap-free indexes, and requires component-count readback.
  • Legacy playback tools now report request acceptance rather than unverified playhead movement or stoppage.
  • Empty QE audio-transition catalogs fail closed, while effect fallback results are explicitly bounded and partial.

Validation

  • Automated contracts cover the repaired behaviors; real licensed-Premiere host execution remains a separate evidence gate.
View release

v1.14.3

Fail-closed OAuth for trusted operators

Added

  • Added optional OAuth resource-server validation with protected-resource discovery, remote JWKS, exact issuer and audience checks, required scopes, and a mandatory trusted-subject allowlist.

Security

  • JWT verification is protected by a pre-auth admission gate, authenticated rate-limit keys are opaque, mixed auth modes fail startup, and the public health response no longer exposes admission counters.
  • OAuth remains an operator boundary; this release does not claim public desktop pairing or per-user Premiere routing.
View release

v1.14.2

Verified host contracts and safer mutation outcomes

Fixed

  • Corrected MCP schema compatibility, CEP argument contracts, sequence timing units, Media Encoder paths, metadata readback, XMP patch merging, and UXP frame filenames.
  • Host mutations now report verified outcomes or explicit fail-closed errors instead of claiming success without observable evidence.

Added

  • Added bounded UXP selection lift and native transition adapters while leaving unavailable track-management and global-redo capabilities explicit.

Safety

  • Automated and contract tests do not replace persistence checks in a licensed Premiere Pro host.
View release

v1.14.1

Reliable npm package verification

Fixed

  • Made package verification isolate its temporary npm tarball and select the package that matches package.json, keeping release validation stable with the current npm CLI.
View release

v1.14.0

Focused workflow packs and review handoff

Added

  • Added focused tool packs for essential work, inspection, delivery, and captions so compatible clients can start with a smaller, task-specific catalog.
  • Added a read-only sequence review report for editorial handoff, plus declared MCP output schemas for the registered tool surface.

Safety

  • Tool packs reduce discoverability only; they do not grant new authority. Review reports redact media paths by default and include marker comments only when explicitly requested.
  • Automated checks validate the package and response contracts. Licensed-Premiere host execution remains a separate verification gate.
View release

v1.13.0

Preview-only project intake for assistant editors

Added

  • Added a bounded, inspect-only project intake preview that evaluates a Premiere project against a facility-supplied template and proposes organization work without changing the project.
  • Added deterministic intake rules, a guided workflow entry, a public facts page, and security and design-partner pilot contracts.

Safety

  • Paths are redacted by default, capture and outputs are bounded, and automated tests remain distinct from licensed-host evidence; Premiere 2026 host execution is still an open gate after the test host hung before CEP panel launch.
View release

v1.12.2

MOGRT values and QE catalog diagnostics

Fixed

  • Allowed string-backed MOGRT and graphic effect properties, with parameter readback status that remains distinct from render verification.
  • Made empty legacy QE effect catalogs fail clearly without a mutation and point connected hosts to the documented UXP catalog and transaction workflow.
View release

v1.12.1

Analytics CSP compatibility

Fixed

  • Allowed Google Analytics collection requests to www.google.com in the restrictive Content Security Policy, matching the current Google tag client.
View release

v1.12.0

Reviewed editorial workflow controls

Added

  • Added local-first editorial plans for organization and platform cutdowns, with previewable recommendations and a guarded UXP organization apply route.
  • Added structured UXP readback requirements, a licensed-host validation runbook, and product-claim drift checks.

Safety

  • Organization plans now require an exact server-issued plan and opaque preview token; changed plans and duplicate source guards are rejected before a UXP mutation.
  • Automated contracts verify response shape, but real licensed-Premiere host validation remains a separate evidence gate.
View release

v1.11.5

MCP safety and interoperability research

Changed

  • Published ten research-backed implementation recommendations for subscription streams, contextual completions, workspace boundaries, resource annotations and canonical URIs, prompt-injection defenses, end-to-end health checks, C2PA inspection, UXP external-launch safeguards, and keyframe verification.

Validation

  • The recommendations are documented planning work; implementation and licensed-Premiere host confirmation remain explicit follow-up gates.
View release

v1.11.4

Claude Desktop UXP token injection

Fixed

  • The Claude Desktop MCPB now prompts for the sensitive Premiere UXP token and injects it into the bundled server process so the authenticated loopback listener starts reliably.

Validation

  • MCPB schema and distribution validation now fail if the token field or environment mapping is removed.
View release

v1.11.3

Premiere 26.3 UXP connection and transcript planning

Added

  • Added a revision-locked transcript rough-cut planner that maps selected source ranges to verified 1x sequence placements and emits descending, non-mutating cut instructions.

Fixed

  • Updated the UXP network manifest declaration for Premiere Pro 26.3 compatibility while retaining exact loopback-only bridge validation at runtime.

Validation

  • Automated tests and cross-platform package gates pass; exact-package confirmation in a licensed Premiere host remains separate.
View release

v1.11.2

Fail-closed Premiere 26.x timeline mutations

Added

  • Added durable local project-context capture, bounded retrieval, enrichment, and non-mutating edit-plan scaffolds with independent source and timeline revisions.

Fixed

  • Trim and split now verify visible timeline geometry; track creation and overwrite placement verify exact postconditions instead of accepting silent no-ops.
  • Effect removal now preflights Component.remove support, including safe handling for unsupported Essential Sound Amplify components.

Validation

  • Automated CEP/QE contract coverage is included; licensed Premiere Pro 26.x host confirmation remains a separate gate.
View release

v1.11.1

Remote static-route stability hotfix

Fixed

  • Extensionless exported routes now resolve to their index file instead of streaming a directory and restarting the Linux HTTP process with EISDIR.
  • Static candidates must remain inside the landing root and resolve to regular files; asynchronous read failures no longer terminate the server.

Validation

  • Regression tests cover extensionless routes and read-stream failures; real Premiere host verification remains a separate gate.
View release

v1.11.0

Evidence-backed third-wave UXP workflows

Added

  • Added eight capability-gated UXP tools for host events, readiness, project sessions, growing media, checkpoints, media health, track state, and source trim and framing.
  • Added a generated supported-actions catalog and schema-backed hybrid benchmark evidence gate.

Fixed

  • Corrected clip-volume conversion from decibels to Premiere's normalized Level value and added readback and batch controls.

Changed

  • Expanded the connected surface to 328 tools and added bounded history, explicit confirmations, timeout budgets, and post-mutation readback.

Validation

  • Automated tests, coverage, generated-document checks, and package validation pass; real Premiere host verification remains a separate gate.
View release

v1.10.0

Stable, bounded UXP workflow expansion

Added

  • Added 21 consolidated, capability-gated UXP tools, expanding the connected surface from 297 to 318 tools.
  • Added native workflows for effects, selections, scene detection, proxies, relinking, metadata, color, Source Monitor, storage, project organization, keyframes, timeline edits, sequences, and encoding.

Changed

  • Bounded project traversal, grouped compatible Adobe actions into transactions, and added stale-state guards, replay protection, and readback evidence.
  • Replaced UXP filesystem full access with an operator-selected workspace while retaining CEP as the production-compatible bridge.

Validation

  • Automated unit, contract, distribution, and coverage gates exercise the expanded surface; real Premiere host verification and latency benchmarking remain pending.
View release

Nontechnical onboarding and safe connection recovery

Added

  • Read-only connection verification, human-readable doctor diagnostics, sanitized support bundles, and an accessible in-panel Connection Center.
  • Deterministic UXP CCX distribution plus native Windows and macOS CEP installer pipelines with fail-closed production signing gates.

Changed

  • Reworked setup around the editor's AI assistant, with Claude Desktop first and npm or manual JSON configuration under Advanced.
  • Aligned the catalog at 280 registered tools, 278 under the default profile, and 297 with the 19 capability-gated UXP tools connected.
View release

v1.8.0

Native transcript edit planning

Added

  • Three read-only, capability-gated UXP tools for native transcript export, native transcript search, and revision-locked edit previews.
  • Deterministic transcript revisions and confirmation tokens so edit plans cannot be applied to a regenerated transcript.

Changed

  • Expanded the connected UXP surface from 16 to 19 tools without changing the 279 core-tool surface.
  • Automatic transcript-to-timeline application remains unavailable until a real Premiere host validates documented source-to-sequence reconstruction.
View release

v1.7.0

Adobe Premiere Pro 26.3 UXP API coverage

Added

  • Six capability-gated UXP tools for track rename, subclip creation, stable marker IDs, Source Monitor positioning, transcript detection, and AAF export.
  • Adobe 26.3 declarations, lint rules, coverage metadata, and contract tests for the supported API surface.

Changed

  • Expanded the connected UXP surface from 10 to 16 tools while preserving explicit host capability and verification boundaries.
  • Separated the stable Adobe 26.3 baseline from beta-only 26.5 declarations.
View release

Added

  • Capability-aware UXP workflows for project inspection and saves, preset sequences, OTIO/FCP XML interchange, transcript languages, Object Mask detection, and Adobe Media Encoder controls.
  • Operation-ID replay protection and explicit verification outcomes for supported UXP mutations.

Fixed

  • Project creation now verifies that Premiere opened the requested project before reporting success.
  • Updated package, panel, client-plugin, and landing metadata for v1.6.0.
View release

v1.5.0

Verified structural edits and silence detection

Added

  • Local source-media silence detection powered by FFmpeg, with Docker and installation guidance.
  • Anonymous, opt-out usage telemetry and an expanded editorial product experience.

Changed

  • Expanded the surface to 279 tools while advertising only tools permitted by the active capability profile.
  • Documented remote media-path constraints and the 277 tools available under the default profile.

Fixed

  • Structural timeline operations now verify applied edits instead of reporting unverified success.
  • Server metadata now reads the package version, and HTTP and filesystem CodeQL findings are resolved.
View release

v1.4.0

Transport, diagnostics, and distributions

Added

  • In-panel connector update discovery and trusted downloads from GitHub Releases.
  • Authenticated MCP-to-UXP WebSocket transport, transcript and caption inspection, event-driven state reporting, operation semantics, and supported video-transition workflows.
  • Recovery diagnostics, export verification, audio/video inspection, capability reporting, and collaboration and AI feature eligibility discovery.
  • Installable Codex, Claude Code, and Claude Desktop distributions.

Changed

  • Expanded the MCP surface to 278 tools and aligned the documentation, plugin metadata, and distributions.
  • Added automated signed CEP connector assets and Claude Desktop bundles to GitHub releases.
View release
