### Description (declared)

Read published Semantic Data Charter models from SDCStudio's public catalog or a package on disk: search the catalog by text or project, describe a model (root record, leaf and component counts by type, Dublin Core with SDCStudio's defaults reported as null, the schema URL pinned to its SHA-256), list its leaves in document order with constraints and identity links, list a component's enumerated values with their codes, and check a package directory. Read-only, no account; the catalog host is fixed at start and no tool takes a URL. Self-hosted MCP server over stdio: pip install sdcreader, then run 'sdcreader-mcp' (or uvx sdcreader).
