Packwright MCP server

Read from the package source without running it. The installed server may list more.

• datapack_buildwrite action

  Run strict structural and authoritative Minecraft 26.2 command validation, then create a deterministic datapack ZIP with pack.mcmeta at its root. Java 25 and setup-version are required; builds cannot bypass vanilla validation. Existing output files require overwrite=true and their current SHA-256.

• datapack_createwrite action

  Create a Minecraft Java Edition 26.2 datapack below the configured workspace. The target must not exist. Supports a no-write dry run and optional namespace load/tick functions.

• datapack_inspect

  Inspect pack metadata, namespaces, resource inventory, hashes, Minecraft 26.2 compatibility, and validator readiness without changing files.

• datapack_test

  Validate commands, then load a staged copy of the pack and run selected GameTests in a disposable Minecraft 26.2 universe. The configured timeout is one shared budget capped at five minutes.

• datapack_validatewrite action

  Run structural checks plus authoritative Minecraft 26.2 dispatcher, registry, and codec validation for every ordinary .mcfunction command. Requires setup-version and Java 25 unless includeVanilla=false; configured Spyglass diagnostics are also available. Invalid packs return normalized diagnostics as a tool execution error.

• minecraft_lookup

  Search locally cached Minecraft 26.2 commands, registries, resource types, and identifiers. This tool never performs network access.

• project_build

  Validate and build separate deterministic datapack and resource-pack ZIPs for an attached project. Existing artifacts require both current SHA-256 values.

• resource_deletewrite action

  Delete exactly one datapack file. Requires confirm=true and the file's current SHA-256; directories are never recursively deleted.

• resource_read

  Read an allowed text resource by typed Minecraft resource ID or exact pack-relative path. Returns its SHA-256 for guarded follow-up writes.

• resource_upsertwrite action

  Create a typed datapack resource or allowed text file. Existing files require overwrite=true and their current expectedSha256. dryRun returns the proposed diff without writing.

• texture_import

  Strictly decode, bound, normalize, metadata-strip, and content-address a PNG supplied inline or through an exact hash-guarded workspace file.

• visual_asset_inspect

  Inspect a paired project, its logical item graph, current draft readiness, bindings, textures, renders, and commit state without changing files.

• visual_capabilities

  Report the truthful Minecraft 26.2 capability boundary and the separately labeled current compiler support for each visual target.

• visual_capture

  Launch the pinned official Minecraft 26.2 client in a disposable deterministic studio and return protocol-v3, representation-bound framebuffer evidence for supported item, block, headwear, entity, or placeable fixtures. Required world/gameplay views are authoritative only for the recorded OpenGL environment. Scale-reference and debug-hitbox views are separately requested augmented QA aids, never W

• visual_commit

  After explicit acceptance, atomically install every proposed datapack and resource-pack file. Official-client evidence can authorize commit only when its proposalBindingStatus is implemented; capture_only block, headwear, entity, and placeable evidence is QA-only until the compiler implements that exact representation. Accepted evidence requires the exact verified report SHA-256, which is bound in

• visual_compile

  Compile a semantic custom-item ModelSpec into exact Minecraft 26.2 item-definition, model, UV, and texture draft assets without changing the paired packs.

• visual_connectwrite action

  Create a guarded multi-file proposal connecting a client item definition to a vanilla carrier through minecraft:item_model, with optional give helper and recipe.

• visual_project_attach

  Associate sibling datapack and resource-pack roots through a guarded project manifest. Can create a new format-88.0 resource pack without moving the datapack.

• visual_render

  Render the selected model-specific scene-review profile with Packwright’s deterministic CPU renderer. All profiles produce bounded original-reference scenes, advisory measurements, an immutable report, individual image resources, and a contact sheet returned as image content.

• visual_revision_createwrite action

  Create an immutable child revision by changing only named parts, materials, display transforms, or selected review-profile metadata against the reviewed spec hash.

• visual_spec_upsert

  Validate a semantic custom-item ModelSpec, including its selected review-profile metadata, and create an immutable, content-addressed draft run. Review profiles stage the same compiled item output and never imply new native target support.

• visual_validate

  Combine paired-pack, model, graph, CPU preview, binding, vanilla-command, and optional GameTest validation. Existing official-client evidence is authoritative by default for supported profiles; set requireClientCapture false only for an explicit fast advisory pass.
