Claude Code + Grok Build plugin marketplace — curated plugins, agent skills, and MCP servers. Two commands to install.
Add the 88plug marketplace once, then install any plugin by name:
/plugin marketplace add 88plug/claude-code-plugins
/plugin install <name>@88plug
Same catalog — Grok reads .grok-plugin/marketplace.json (SHA-pinned) automatically when you add this repo as a marketplace source:
grok plugin marketplace add 88plug/claude-code-plugins
grok plugin install <name>@88plug --trust
Or in the TUI: /marketplace → add source 88plug/claude-code-plugins → select a plugin → i.
No environment variables. No API keys for the catalog path. Uses your existing Claude Code or Grok Build setup.
Tip
Claude: enable auto-update once (/plugin → Marketplaces → 88plug → Enable auto-update).
Grok: grok plugin marketplace update then grok plugin update to refresh pins and installed plugins.
Every 88plug plugin is published with a full commit SHA in .grok-plugin/marketplace.json.
Grok re-verifies HEAD == sha after clone. To refuse unpinned remotes from any marketplace:
# ~/.grok/config.toml
[marketplace]
require_sha = trueor GROK_MARKETPLACE_REQUIRE_SHA=1. Default is off; 88plug catalogs already pin so this is safe for our entries.
88plug is a curated plugin marketplace for developers who run AI coding agents all day — Claude Code and Grok Build. You get productivity plugins (memory, compaction, guardrails, investigation) and MCP servers (search, desktop control, package versions) without cloning repos or wiring config by hand.
Each entry is a full plugin or MCP server in its own repo. This hub is only the catalog index — install with /plugin install <name>@88plug (Claude) or grok plugin install <name>@88plug --trust (Grok), then work. Claude versions are YEAR.MONTH.BUILD (rolling). Grok installs pin the exact commit SHA from .grok-plugin/marketplace.json and re-verify it after clone.
| Area | What you get |
|---|---|
| Claude Code + Grok Build | Same catalog; Grok uses SHA-pinned .grok-plugin/ entries |
| Plugins | Hooks, skills, slash commands, agents for coding agents |
| MCP servers | One-command MCP for search, DeepWiki, desktop, OS, package versions |
| Marketplace install | Add once, then install <name>@88plug |
| Rolling + pinned | Claude: YEAR.MONTH.BUILD; Grok: full commit sha on every url source |
| Zero config | No env vars or API keys for the catalog path itself |
Claude versions are YEAR.MONTH.BUILD (what claude plugin list shows). Grok
installs pin the full commit SHA from .grok-plugin/marketplace.json. Each card
has Claude and Grok install commands. Grouped by job — scan the H2 that matches
your problem.

Updating & versioning
Third-party marketplaces have auto-update off by default. Turn it on once
(/plugin → Marketplaces → 88plug → Enable auto-update) and Claude Code refreshes
the catalog and updates installed plugins at startup, then prompts /reload-plugins.
Prefer to do it by hand:
/plugin marketplace update 88plug
/plugin update <name>@88plug
/reload-plugins
Org-wide, an admin can add 88plug to extraKnownMarketplaces with auto-update enabled
in managed settings.
Refresh the marketplace (new SHA pins), then update installed plugins:
grok plugin marketplace update
grok plugin update
Or reinstall one plugin to the current catalog pin:
grok plugin install <name>@88plug --trust
Claude: YEAR.MONTH.BUILD (auto-stamped; linked hash is the exact commit).
Grok: full commit sha in .grok-plugin/marketplace.json, re-verified after clone.
If your installed version or pin differs from the catalog, update it.
Plugins should be invisible until you need them. Each one earns its slot by closing a specific failure mode in long-horizon AI-assisted work — compaction loss, stale package versions, yield-back, classifier false positives, and similar agent failure modes.
See CONTRIBUTING.md for the full workflow, naming convention, quality
bar, and CLA terms. Short version: build your plugin in its own 88plug/<plugin> repo with
a valid .claude-plugin/plugin.json, PR an entry to this hub's
.claude-plugin/marketplace.json, and sign the
CLA on your first PR.
Plugin code never lives in this repo — only the marketplace index.
