Is it safe to install today?

Type a skill, plugin or MCP server and pick your agent. The answer comes from last night's real install in a clean sandbox (2026-11-14): 910 of 1070 installs passed, 25 only need your API key, 133 have failed two nights running and 2 are on a one-night wobble we re-check tomorrow.

New test baseline since 2026-11-12: newer releases of all 5 agents (Claude Code 2.1.319, Codex 0.167.0, Grok Build 1.0.77, Cursor 2026.11.05, Pi 1.5.0). Scores before 2026-11-12 came from older agent versions and are not like-for-like. "Confirmed broke" and "really fixed" only compare nights on the same baseline. What changed

Our mistake: the new sandbox image was also missing uvx, the tool that starts Python MCP servers. So MCP time, MCP fetch, MCP git and claimidx (20 installs across all 5 agents) failed on Nov 12 and 13 for our reason, not theirs. All 20 passed on Nov 8. Treat those 4 as untested until the next run on the fixed image. The same Nov 12–13 runs also charged a first-time npm download against each agent's MCP connect timeout (Claude Code 30s, Cursor 60s), so several working npx servers failed for our reason. The harness now pre-fetches those packages into a shared npm cache before the health check; connect timeouts themselves are unchanged and still each agent's default.

Start typing to check a tool.

No agent version changed since 2026-11-13, so no update-shaped breakage tonight.

What is this page?

It's the always-current version of the SkillMaxx daily install report. Every night we run the real install command for every listed add-on in each agent that supports it, retry failures once, and only call something broken after two bad nights. Dated pages are the archive; this URL always shows the newest run.

Tonight's verdicts by agent

AgentInstallsPassedNeeds an API keyBroken (2+ nights)Pending re-checkFlaky
Claude Code37134352211

Grok Build38635452613

How to read this: Needs an API key means the add-on asked for a key or token our keyless sandbox doesn't have, so it's probably fine on your machine once you add yours. Pending failed tonight (after a retry) but worked last night; we only call it broken if it fails again tomorrow. Flaky flip-flopped lately or only passed on retry.

Standout pick

MCP time (reference) (fixed after failing 2+ nights): installed cleanly in 5 agents (Claude Code, Codex, Grok Build, Cursor, Pi), 92k GitHub stars. Time and timezone conversion

How we pick: clean in every agent we tested it in, nothing flaky or pending, new and really-fixed add-ons first, then GitHub stars. Never sponsored.

Confirmed broke (2)

Really fixed (41)

Pending re-check (2)

Failed tonight, worked last night. Not calling these broken yet.

Flaky (9)

These flip-flopped between pass and fail recently. They pass tonight, but give them a retry if one hiccups on you.

Needs your API key (25)

Not broken, just shy without credentials. Our sandbox has no keys on purpose.

Everything failing 2+ nights (133)
