OKF::MCP is a thin Model Context Protocol shell over the okf kernel: it maps MCP tool calls onto okf's pure library API so any MCP-capable agent host can discover, orient in, search, and read Open Knowledge Format bundles on the machine. Bundles are named by the same registry slugs the okf CLI and server resolve, search federates across bundles through one shared corpus, and every payload is bounded with its truncation visible.

OKF Pro is a profile of OKF (Open Knowledge Format) — "pro" as in profile, the term of art for a constrained application of a general format, not as in a paid tier; this is Apache 2.0 like the rest of the ecosystem. It turns a bundle into a working memory an agent is held to. `okf pro setup` writes the bundle and the governance around it — the Claude Code hooks, the pre-commit hook, the CI workflow, the skill — and `okf pro hook` runs one gate against one hook event: reconcile before you add, keep the board and the work in step, attest what you did not verify, close the day with a counted snapshot. The same invariants run again as `okf pro audit`, the CI door. Every conformance and curation question is the okf gem's to answer; what this gem owns is the policy on top and the contract underneath it — blocking checks fail closed, feedback checks fail loud, and no check ever fails silent.

okf-tui is a full-screen terminal UI over OKF (Open Knowledge Format) bundles. It reads a bundle in the order the spec intends — index.md, log.md, then each directory — renders concept bodies as markdown, and finds within them. It browses and configures the per-user bundle registry, switches the active bundle, and searches every bundle in scope through one shared index, so the scores compare between them. It shows each bundle's standing (conformance and curation) wherever the bundle is named, and its knowledge graph as a set of facets to narrow by or follow into the file. It invents no analysis: the okf gem's pure core answers every question on screen.
