What Open Knowledge CLI is

Open Knowledge CLI is free, open-source tooling for creating, checking, searching, and sharing Markdown knowledge bases for people and AI agents. Knowledge stays in plain Markdown and YAML under a Git workflow. The CLI can create a managed knowledge base or adopt one from repository Markdown, then search it locally and deterministically without an LLM or embedding service. It can start a local web viewer and publish configured viewer or MCP outputs from checked knowledge. Its read-only MCP server lets clients list and read files, search, run explicit semantic queries, and validate a bundle. The site describes compatibility with Codex, Claude, Cursor, and local agents; workflows and jobs support Codex, Claude Code, and OpenCode. Platforms listed are API, Linux, macOS, and Windows. Shell installation supports macOS and Linux on amd64 and arm64, while npm supports release platforms including Windows assets when available. Installers verify SHA-256 release checksums and can verify GitHub or Sigstore attestations. Telemetry is enabled by default but can be disabled with `--no-telemetry`.

Who it suits
