## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why layer_set_opacity is rated Medium

The tool performs a reversible modification of visual layer state (opacity adjustment). While the effect is state-changing and could impact rendered output, it is not destructive (can be undone by setting opacity again), does not involve code execution, and does not affect data persistence or finances. This fits the Write category—creates or modifies data reversibly.

From the tool's own definition: "Tool name 'layer_set_opacity' indicates modification of a layer property (opacity value). The 'set_' prefix clearly denotes a write/update operation. Description is empty, limiting certainty."

## Use case

AI agents use layer_set_opacity to create or update resources in Mcp Anything, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Anything environment.
