Install a listing

The catalog catalogs official tools — harnesses, CLIs, MCP servers, memory engines, agents, skills, plugins, and loops. You discover them here; the Positronick CLI installs them from their source.

Registry types

• Harness — Agentic coding tools you run in your terminal — the agent loop itself.
• CLI — Official command-line tools for shipping and operating software.
• MCP — Official Model Context Protocol servers that give agents real tools.
• Memory — Memory and context engines/APIs for agents — persistent facts, profiles, and retrieval (not merely an MCP wrapper).
• Agent — Official SDKs and frameworks for building and running AI agents.
• Skill — Agent skills and methodology packs that upgrade your coding agent.
• Plugin — Official plugins that extend coding agents like Claude Code.
• Loop — Reusable agent loops — run a task, check an exit condition, and iterate until done.

1 — Install the CLI

2 — Install by type and slug

Replace <type> and <slug> with values from a catalog listing page. Most types take --run so the tool is wired and started when that makes sense; loops omit --run (they install as a kickoff prompt).

Every listing page also shows a ready-to-copy install line (the page’s installCmd when the publisher set one, plus the CLI form above). Prefer the page command when you want the exact vendor install string.
