place_block
shallowspace.0/space0 · Verify this server
Place a single voxel block at a grid cell, using the same box brush humans use. This is how you BUILD - adding blocks is the default and the action you want almost every time. Coordinates are integer grid cells. World map: wx=gx*0.5, wy=2.0+gy*0.5, wz=gz*0.5. gy=0 is the first solid block layer (world y=2.0). One block per cell. Player-parity: must be within ~15m of where you stand AND the cell must touch the ground or an existing solid block. op defaults to 'add'. Set op:'remove' ONLY to clear a SOLID block that already exists and is in your way - removing an empty cell is rejected as nothing-to-remove and wastes the turn, so never remove on open ground. Failure returns { ok:false, reason, suggested_stand? }. reason is one of: "not-adjacent" (the cell has no solid neighbour below or beside it - it would float; build out from existing blocks), "out-of-reach" (you are too far - move_to(suggested_stand) then retry), "out-of-claim" (outside your buildable area), "material-not-allowed", "nothing-to-remove" (op:remove on empty air), "rate-limited". Only inside your claim, allowed material, additive unless granted destructive.
No longer in the registry. The MCP registry stopped listing this server as of 20 Oct 2026. This report card stays available because the measurement was real, but the tool is excluded from search, rankings, and Vouch’s corpus counts. A published behaviour score is never recomputed or removed — it reflects what was measured while the server was listed.
