About Kastra

Control what your AI is allowed to do. Sub-millisecond authorization for every prompt, tool call, shell command, and API request. Before an action runs, Kastra evaluates attribute-based policy in under one millisecond and returns allow, deny, redact, or hold. Recorded decisions form a cryptographically chained audit trail so operators, auditors, and agents can explain why something was permitted. Use the Kastra HTTP API from production agents, install Kastra Edge on developer machines to govern Claude Code, Cursor, and Codex, or connect an MCP client to read governance data.

About Pacwich

Monorepo tooling that works on top of Bun, npm, and pnpm workspaces, with a CLI and TypeScript API. This package is the continuation of the original, now deprecated, bun-workspaces package. bun-workspaces users can expect minimal to no changes on average. CLI global install: Your pacwich command will still resolve to a local install when available. bun add -g pacwich # Print help for installing completions pacwich completion # Attempt to automatically install completions for your shell pacwich completion install Local install: Note the pacwich command works in your package.json scripts even without a global install.
