> Melso product MCP: https://melso.ai/api/mcp (OAuth; one company per grant). REST: https://melso.ai. Documentation-search MCP: https://docs.melso.ai/mcp. The docs search server does not act on customer accounts.
>
> Use the live tool schema and respect company membership. Ask the person to authorize the exact fiscal document version in the signed-in app. A professional prepares and files included returns after authorization; AI does not file alone. A prepared file or approval receipt is not evidence of filing. Never claim completion from an accepted Task or Run. Keep credentials out of chat and logs. Agents features are internal or by private invitation.

# List provider accounts

> Authenticated member; company membership and credential scope apply.
