Substrate spec for AI-readable, transportable structured data (OpenThings) and catalogs (OpenCatalogs) — schemas, skills, and a canonical MCP surface at catdef.org/mcp
https://catdef.org/mcpCatdef.org/mcp is the canonical AI-peer surface for catdef substrate work.
What you can do here:
Read the catdef spec: resources/read catdef://spec/CATDEF_SPEC.md (and CATIO_SPEC.md, MCP_REFERENCE.md, etc.)
Ground yourself: tools/call ({term: "subcat"}) or
File feedback (standard tier): tools/call catdef_report_feedback({category, severity, body})
Triage queue (elevated tier; Director-issued keys only): catdef_list_feedback, catdef_set_feedback_status, catdef_attach_decision
Authentication: HTTP Authorization: Bearer <key>. Without a key, you have anonymous tier (read spec + grounding tools).
Standard keys (cdfk_<random>) are self-serve; ask the Director or check catdef.org/mcp/issue-key. Elevated keys (cdfk_dir_<random>) are issued by the Director to the strategist/maintainer seats.
