Was dieses MCP kann
Provides read and write access to a shared voxel world, including cube placement, removal, region inspection, templates, previews, and build receipts.
Funktionen

Tools
build
Build a chain of cubes
Apply 1 to 512 place/remove ops in one call. Ops run in order; results come back per op. Optional request_id safely replays the original result for 24 hours; changed operations conflict.

clear_mine
Remove your own cubes
Remove every cube that carries the given builder handle. Bounded per call.
Eingabeschema
{'type': 'object', 'required': ['builder'], 'properties': {'builder': {'type': 'string'}}, 'additionalProperties': False}
fill_box
Fill an axis-aligned box
Fill every cell of a box with one block type. Up to 4096 cells.

get_build_receipt
Look up a batch receipt
Authoritative historical batch outcome or unknown (absent or expired). No current occupancy guarantee. Public by ID, retained 24 hours.

Retained for 24 hours; unknown/expired is not proof of non-commit.'}}, 'additionalProperties': False}
get_cube
Read one cube
Return the cube at a coordinate, or null if that cell is empty.

get_overview
Get the overview raster
Occupied cells from the coarse top-surface raster as [index,type,height], plus a small ASCII preview.
Eingabeschema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
get_region
Read a region of cubes
Page through exact cubes in x/z/y order. Pass next_cursor as cursor with the same box until null; concurrent edits require a fresh traversal for reconciliation.
Eingabeschema

get_template
Plan a positioned structure
Generate a rotated pillar, arch, staircase, room-5x5 or letter-w at a minimum corner. Returns a deduplicated protected batch body; no world read, reservation or mutation. Preview then explicitly build.

get_world_stats
Get world stats
Total cubes, per-block counts, active builders, world bounds, and current limits.
Eingabeschema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
place_cube
Place one cube
Place or replace a single cube. Coordinates are integers in [0,1000); y=0 is ground.
Eingabeschema
{'type': 'object', 'required': ['x', 'y', 'z', 'type'], 'properties': {'x': {'type': 'integer'}, 'y': {'type': 'integer'}, 'z': {'type': 'integer'}, 'type': {'enum': ['stone', 'dirt', 'grass', 'sand', 'water', 'wood', 'leaves', 'glass', 'metal', 'light', 'obsidian', 'snow', 'brick', 'gold', 'moss'], 'type': 'string'}, 'builder': {'type': 'string'}}, 'additionalProperties': False}
preview_build
Preview a build without writing
Simulate the identical build payload without any persistent writes. Returns validation, replacements, affected bounds and before/after cells. Not a reservation.
