# Update asset

Canonical URL: https://sosoapi.ai/docs/mcp/update-asset

`sosoapi_update_asset`

Change an asset's title, description or tags (editor role).

## Profiles and transports

Profiles: full

Transports: stdio, http

Choose core or full to control which tools your client sees; this does not change its permissions. Local file upload requires stdio and is unavailable over HTTP. Set SOSOAPI_OUTPUT_SCHEMAS=1 to include output schemas in discovery. Tools return structured results with or without that setting.

## Permissions and side effects

Annotations help clients describe a tool. Each call still checks the user’s authentication, role, resource access and capability grants.

## Structured output

This schema describes structuredContent in a successful tool result. The MCP response also includes content and may set isError when a call fails. For publishing, read the post’s final result rather than treating an accepted request or text response as confirmation. The linked API operation explains permissions and retry rules.
