Problem: Agents need tools, but the current options are awkward. You either wire up tools manually in your codebase, or you spin up MCP servers that bundle more than you need. Neither is discoverable, shareable, or safe to run.

Enact is a package manager for executable tools:

  enact search "web scraping"
  enact run enact/firecrawl --args '{"url": "https://example.com"}'

Key differences from MCP: - Tools, not servers. Install one capability, not a bundle. - Registry with discovery. Agents can search for tools at runtime. - Containerized. Run untrusted tools safely. - Sigstore signing for trust.

Live registry: https://enact.tools

CLI: npm install -g enact-cli

Would love feedback on the manifest format and whether this solves a real problem for folks building agents.
