Response

Status	Body	Meaning
`200`	flag.defsOut	ok
`default`	problem-details	refused

200 body — 6 fields.

Field	In	Type	Always	Description
`data`	body	flag.DefRow[]	—	Data is every definition in the caller's (org, project) store, by key.
`data[].definition`	body	any	—	Definition is the flag-definition document the evaluator consumes, kept BYTE-FOR-BYTE as it was written.
`data[].key`	body	string	—	Key is the flag's primary key in the caller's (org, project) store, and the name evaluation looks it up by.
`data[].updated_at`	body	string	—	UpdatedAt is when the definition was last written, RFC 3339 UTC.
`data[].updated_by`	body	string	—	UpdatedBy is the email of the principal who last wrote it.
`data[].version`	body	integer (int64)	—	Version is 1 when the key was created and rises by one on every overwrite.

Failure carries the platform error shape — see Errors.

MCP reaches flag through the flag tool, which names its 8 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,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_flag_activity"
         }
       }
     }'
