# docker mcp catalog tag

**Description:** Create a tagged copy of a catalog

**Usage:** `docker mcp catalog tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]`










## Description

Create a new catalog by tagging an existing catalog with a new name or version.
This creates a copy of the source catalog with a new reference, similar to Docker image tagging.




## Examples

  # Tag a catalog with a new version
  docker mcp catalog tag mcp/my-catalog:v1 mcp/my-catalog:v2

  # Create a tagged copy with a different name
  docker mcp catalog tag mcp/team-catalog:latest mcp/prod-catalog:v1.0

  # Tag without explicit version (uses latest)
  docker mcp catalog tag mcp/my-catalog mcp/my-catalog:backup
