### Description (declared)

CDIF (CODATA Cross-Domain Interoperability Framework) descriptions of published Semantic Data Charter models: Discovery, Data Description with every variable, Codelists and the sentinel domain for the sixteen exceptional values, as JSON-LD, the model's schema cited by URL and SHA-256. One tool, write_cdif, over the same function the CLI calls; validated in the package's CI with CDIF's own framing, JSON Schema and SHACL checks. Read-only apart from the document it returns; no account; the catalog host is fixed at start and no tool takes a URL. Self-hosted MCP server over stdio: pip install sdccdif, then run 'sdccdif mcp' (or uvx sdccdif mcp).
