Context Cost

~1,793Tokens (tool definitions)
~1.2 KBTypical response size
Moderate attention impact (1.40% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢get_template(id, x, y, z, rotation, ...)

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.

  "properties": {},
  "additionalProperties": false
}
🟢get_region(x, z, w, d, y, ...)

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.
