- Notes
- Composer's earlier official MCP repository (invest-composer/composer-trade-mcp) no longer loads (checked 19 Oct 2026); we could not confirm on an official page when or whether it was discontinued. Composer joined SoFi on 23 Jun 2026. Composer says live trading is not available outside the US. Capability reflects the developer API, not a consumer agent feature.
