Changes
Removed
- The
auto_exchanges tool is gone. Exchange connections are no longer part of the documented Auto surface, so listing, connecting and disconnecting venues is no longer exposed here. The three operations are recorded in manifest.json under unexposed, so the drift check still accounts for every documented /v2 operation. The endpoints remain reachable over the API for anyone who needs them.
Changed
validate_symbol moved to auto_validate. It is now auto_validate with method=symbol, taking exchange and symbol, and returns valid: true/false with the unsupported case reported as a validation error. The default method=query behaviour is unchanged.- Eleven tools, down from twelve.
- Signing guidance everywhere — server instructions,
auto_query_write, README, install docs, the desktop bundle and the registry entry — now describes ELFA_HMAC_SECRET as signing Auto mutations that are not plain notifications, rather than exchange linking and order placement.
