Implementation Reference

• packages/cesium-mcp-bridge/src/commands/layer.ts:276-291 (handler)

  The actual handler logic that modifies the Cesium layers' visibility.

  setLayerVisibility(id: string, visible: boolean): void {
    const layer = this._layers.find(l => l.id === id)
    if (!layer) return
    layer.visible = visible
    const refs = this._cesiumRefs.get(id)
    if (!refs) return
    if (refs.dataSource) refs.dataSource.show = visible
    if (refs.entity) refs.entity.show = visible
    if (refs.labelEntities) {
      for (const e of refs.labelEntities) e.show = visible
    }
    if (refs.tileset) refs.tileset.show = visible
    if (refs.imageryLayer) refs.imageryLayer.show = visible
    if (refs.movingEntity) refs.movingEntity.show = visible
    if (refs.trailEntity) refs.trailEntity.show = visible
  }

• packages/cesium-mcp-runtime/src/index.ts:560-571 (registration)

  MCP tool registration for 'setLayerVisibility'.

  _registerTool(
    'setLayerVisibility',
    '设置图层可见性',
    {
      id: z.string().describe('图层ID'),
      visible: z.boolean().describe('是否可见'),
    },
    async (params) => {
      const result = await sendToBrowser('setLayerVisibility', params)
      return { content: [{ type: 'text' as const, text: JSON.stringify(result ?? { success: true }) }] }
    },
  )

• packages/cesium-mcp-bridge/src/bridge.ts:289-291 (helper)

  setLayerVisibility(id: string, visible: boolean): void {
    this._layerManager.setLayerVisibility(id, visible)
  }
