MCP reaches tax through the tax tool, which names its 26 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,

       "params": {
         "name": "describe",
         "arguments": {
