skill-of-skills
Registry code: 1748e4edf85b1c4b
Skill of Skills is a quality-ranked, cross-platform directory of AI coding skills, plugins and MCP servers (Claude Code, Cursor, Codex, Windsurf, Cline, n8n). Composite ranking uses normalized signals: 45% structural quality, 20% star velocity, 12% star gravity, 8% recency, 10% social activity, and 5% user ratings; the weighted sum is multiplied by the highest applicable reputation factor (baseline 1x, official 1.5x, known vendor 1.25x, verified 1.15x, capped at 1.5x), then by 1 - min(0.3, 0.03 × dependency-vulnerability count) when that count is at least 5 (otherwise 1), with the result…

- Is skill-of-skills live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is skill-of-skills free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does skill-of-skills have?
- 6 tools: get_collection, search_skills, get_skill, compare_tools, demand_pulse, list_collections.
- Is skill-of-skills safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
demand_pulse reads open 5h ago
Public, k-anonymous demand signal from the directory: trending searches, most-saved and most-installed tools. Aggregates only — sourced from ≥5 distinct anonymous sessions per entry.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {} }arguments 5 lineslist_collections reads open 5h ago
The curated buyer-intent collections (e.g. mcp-servers, testing-qa, browser-automation). Use get_collection for the ranked tools inside one.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {} }arguments 5 linesget_collection reads unknown 5h ago
Quality-ranked tools inside one curated collection. Critical-risk tools are excluded by default (risk_filter); every result carries risk_level and risk_reasons.

Full-text search over the Skill of Skills directory (AI coding skills, plugins, MCP servers across Claude Code, Cursor, Codex, Windsurf, Cline). Results are ranked by the quality-first composite score, not popularity; when no tool matches every term, the closest partial matches are returned instead (match_mode: "any"), most relevant first. Critical-risk tools are excluded by default (risk_filter); every result carries risk_level and risk_reasons. Scores are evidence, not endorsements.

Full quality profile for one tool by slug (slugs come from search_skills / get_collection): score breakdown, structural signals, risk level and reasons, platforms, repo link. Direct lookups return any active tool regardless of risk — the risk assessment is part of the answer, not a filter here.

Side-by-side quality profiles for 2–5 tools by slug. Same fields as get_skill; ordering follows the request, not rank.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id1748e4edf85b1c4b.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/1748e4edf85b1c4b/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
