minecraft-java-fabric-claude-plugin

Orchestrates a primarily-natural landscape or region in a live Minecraft Java world — terrain, landforms, biomes, water, natural scenery, named natural wonders, and designed caves. Sequences the terrain leaf skills and threads one shared coherence context (one datum, one continuous recipe, one palette, one biome+scatter plan, one integration pass) so the result reads as one coherent place. Use for canyons, mountains, islands, coastlines, river valleys, forests, cave systems, and recreations of natural wonders. Tier-2 orchestrator.

Orchestrates a working or connective system in a live Minecraft Java world — a redstone contraption or automatic farm, a transit line, a nether hub, a mechanism — together with its housing and right-of-way. Sequences design, functional verification, build, the terrain cuts/grades it needs, and one integration pass so the machine works AND sits in the world without a raw seam. Tier-2 orchestrator.

Designs and blueprints monuments, sculptures, and build-art in a live Minecraft Java Edition world — giant statues, organic creatures and dragons, abstract sculpture, pixel art and murals, large 3D text and logos. Produces solid or shell-only figurative forms with no habitable interiors, using pixel-grid image mapping, organic-curve construction, palette-gradient mapping, and armor-stand detailing. Use when the user wants a statue, sculpture, monument, memorial, mural, pixel art, logo, giant text, or a large creature. Part of the minecraft-builder workflow.

Verifies a Minecraft Java Edition build in-world after each phase — checks the plan was carried out as specified, that the result fits the world cleanly (no dangling edges, blocked paths, or unintended overrides), and proposes concrete course corrections. Use after every major phase of executing a build plan, as the build's self-correction checkpoint. Part of the minecraft-builder workflow.

Designs, plans, and verifies complex redstone and mechanical contraptions in a live Minecraft Java Edition world — item sorters, hidden and piston doors, automatic farms, mob-spawner collectors, minecart networks and roller coasters, water and bubble elevators, note-block music, traps, and decorative machines. Java-correct: uses Java redstone mechanics (quasi-connectivity, deterministic timing) and avoids patched-out tricks. Designs ship with functional in-world verification and automated correction. Use when the user wants a redstone build, an automatic farm, a contraption, or any working machine. Part of the minecraft-builder workflow.

Designs and blueprints world-spanning transit and infrastructure networks in a live Minecraft Java Edition world — rail lines, roads and highways, nether-hub transit, bridges, tunnels, elevators, docks, and airports — the connective network between separate builds. Chooses the network topology and routes the links. Use when the user wants to connect two or more sites, build a transit network, a nether hub, a highway, a bridge, a tunnel, or a rail line between places. Part of the minecraft-builder workflow.

Grounds a finished build into the surrounding Minecraft Java world so it reads as belonging there, not dropped on — erodes an apron around the build's footprint while protecting the build itself, then re-materializes the apron to match the surrounding palette (the programmatic talus-skirt). Also naturalizes existing vanilla terrain. Runs as the required Integrate gate after any footprint-bearing build. Tier-3 leaf.

Composes recognizable real-world natural wonders in a live Minecraft Java world — Grand Canyon, Niagara, Uluru, Halong Bay, Bryce, Devils Tower, and the like — by identifying 2-4 signature features and building them from a library of reusable formation primitives as one continuous recipe. Recognizability comes from the signatures and credible proportions, not raw size. Tier-3 leaf, invoked by build-natural-world (was: natural-landmarks).

Authors naturalistic terrain in a live Minecraft Java world — mountains, valleys, hills, rivers, lakes, coastlines, islands, plateaus — as one continuous sampler-graph recipe, verifies it offline, and emits executable phases. Produces eroded, mask-materialized, biome-blended terrain that reads as real, never stacked rectangles or terraced ziggurats. Tier-3 leaf, invoked by the build-* orchestrators (was: terraforming).

Step 4 of 4 of the Minecraft Java MCP setup. Register the running minecraft-java MCP server (the Fabric mod) with Claude (Claude Code or Claude Desktop) so the Java world tools become available, then verify the connection with a live test call. Use when the user has the MCP server running and needs to connect Claude to their Minecraft world.

Step 3 of 4 of the Minecraft Java MCP setup. Configure the MCP mod's config.json (host, port, auth, tool categories), launch Minecraft or the dedicated server, verify the embedded MCP server is listening on /healthz, and capture the bearer token for remote setups. Use when the user has the MCP mod and Fabric API installed and needs the MCP server configured and running.

Orchestrates a populated place in a live Minecraft Java world — a village, town, city, district, or a building together with its grounds and context. Sequences layout, per-building design, transit, designed grounds, grading, and one integration pass, threading a shared architectural/material vocabulary and site datum so the place reads as ONE settlement rather than a patchwork of fine buildings that don't cohere. Tier-2 orchestrator.

Orchestrates a single named or standalone structure and the ground it sits on in a live Minecraft Java world — a building, a real-world or fictional replica, a statue or monument, a player house, or a bridge as an object. Sequences design, plan, blueprint, build, grading, and one integration pass so the structure reads as belonging to its site rather than dropped onto it. Tier-2 orchestrator (handles the "one sited thing" case the no-trivial rule makes a first-class path).

Designs and blueprints specific named buildings and building complexes in a live Minecraft Java Edition world — real-world replicas (historical and modern), pop-culture replicas (Hogwarts, Minas Tirith), user-described originals, and generative-style fictional buildings — with deep research, advanced building technique, and heavy reuse of defined structure modules. Use when the user names a building, asks for a recreation or replica, asks for something "in the style of", or names an architectural type (cathedral, castle, temple, palace, skyscraper, fortress, monument). Part of the minecraft-builder workflow.

Designs and blueprints whole cities and city districts in a live Minecraft Java Edition world — real-world replicas (modern and historical), pop-culture replicas, and original cities. Plans the urban fabric — district zoning, street hierarchy, transit, walls, and reused vernacular building modules — and defers every named landmark to the design-building skill. Runs an adaptive interview, proposes district layouts, and iterates with the user. Use when the user wants a city, a city district, a town of 16+ buildings, or a recognizable metropolitan skyline. Part of the minecraft-builder workflow.

Designs and blueprints intentionally designed outdoor space in a live Minecraft Java Edition world — formal gardens, parks, plazas, courtyards, hedge mazes, fountains, parterres, topiary, cloister gardens, estate grounds. Covers French formal, Italian, English landscape, Mughal, Japanese, Chinese, modernist, and other traditions. Geometric and intentional — the deliberate counterpart to the naturalistic terrain-shape skill. Use when the user wants a garden, park, plaza, courtyard, hedge maze, fountain, or designed grounds. Part of the minecraft-builder workflow.

Designs and blueprints a player's base of operations in a live Minecraft Java Edition world — a place to live, store, craft, enchant, and display from — not NPC villager housing. Runs an adaptive interview, proposes ASCII / Markdown / Mermaid blueprints, iterates with the user until approved, then writes the build plan. Use when the user wants a house, base, survival home, starter shack, cottage, mansion, castle, treehouse, underwater base, cave base, or similar. Part of the minecraft-builder workflow.

Designs functional, customized villages and settlements in a live Minecraft Java Edition world — hamlets of a few buildings up to standard villages of 5–15 — by reusing standard Minecraft village building types adapted to the biome and the user's request. Runs an adaptive interview, proposes layout options, iterates with the user, and respects Java Edition village mechanics (iron golems, beds, workstations, bells, raids). Use when the user wants a village, hamlet, town, settlement, or trading hub. Part of the minecraft-builder workflow.

Turns a Minecraft build plan into named, reusable structure definitions saved inside the world, so build elements can be placed, copied, and iterated later without any external state. Use after planning, to create or update the structure library for a build. Part of the minecraft-builder workflow.

Captures build requirements for a Minecraft Java Edition world, interviews the user to resolve ambiguity, and produces a detailed, fully-resolved build plan that a small model can execute mechanically. Use when starting a new Minecraft build or feature, or when a build request must be turned into a concrete plan before any blocks are placed. Part of the minecraft-builder workflow.

Reviews a completed Minecraft build — the plan, the execution, what worked and what did not — and records reusable process lessons in Claude's project memory so future builds go better. Use after a build is finished or a build session wraps up. Part of the minecraft-builder workflow.

Executes a detailed Minecraft build plan step by step — placing, filling, cloning blocks and stamping structures exactly as specified, with no redesign or improvisation. Use to carry out a plan.toon produced by exec-plan once it is detailed enough to follow mechanically. Part of the minecraft-builder workflow.

Step 1 of 4 of the Minecraft Java MCP setup. Install Minecraft Java Edition with the Fabric loader — either a single-player client or a headless dedicated server — as the foundation the MCP mod runs inside. Use when the user wants to set up Minecraft Java for AI/MCP control from scratch, or asks how to get Fabric running so Claude can build in their world.

Step 2 of 4 of the Minecraft Java MCP setup. Download the minecraft-java MCP mod jar and its matching Fabric API jar and install both into the Minecraft mods folder. Use when the user has Minecraft Java with the Fabric loader ready and needs the MCP mod and Fabric API installed.

Researches real-world buildings, cities, landmarks, vehicles, and mechanisms so they can be represented faithfully as Minecraft structures. Use when a build request references a real or historical thing and the exec-plan or exec-blueprint skill needs accurate proportions, layouts, materials, or details. Part of the minecraft-builder workflow.

Investigates the current state of a Minecraft Java Edition world — terrain, biomes, existing structures and builds, player surroundings, and anything else needed to ground a build plan. Use before planning a build, or whenever the user asks what is in the world, what is around them, or where there is room to build. Part of the minecraft-builder workflow.

Designs deliberate subterranean space in a live Minecraft Java world — cave systems, cavern halls, ravines, lava tubes, mines, vaults, and the surroundings of an underground base — as opposed to the random vanilla caves the world already has. Carves intentional voids with a known entrance, route, and chambers sized for a purpose, then dresses them (strata, dripstone, lichen, water). Tier-3 leaf, invoked by build-natural-world / build-structure / build-settlement.

Designs the planting and biome ecology of a finished terrain in a live Minecraft Java world — what plant communities grow where, species mixes, densities, and ecotone transitions — and emits the scatter recipe. Use after terrain shape + biome assignment, to dress a landscape with vegetation that reads as a real ecosystem rather than a uniform sprinkle. Tier-3 leaf, invoked by build-natural-world / build-settlement.
