## Initial state
The expected state is the final state of
[`TMCP003` Initialize the MCP server](/tests/TMCP003)
## Procedure
### Step 1
The client calls `list_all_tags` with no arguments
```json
{
  "id": 2,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "list_all_tags",
    "arguments": {}
  }
}

```
### Step 2
Verify the response contains all tags sorted alphabetically.
`bar:baz` appears as one entry (not split into `bar` and `baz`).
`bar:baz` sorts before `foo`.

```json
{
  "id": 2,
  "jsonrpc": "2.0",
  "result": {
    "structuredContent": {
      "tags": ["bar:baz", "foo"]
    }
  }
}

```
