    How to connect

    How to connect Skill of Skills to Claude

    The server address to paste into Claude settings:

    https://skills.911fund.io/api/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect Skill of Skills to ChatGPT

    The server address to paste into ChatGPT settings:

    https://skills.911fund.io/api/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    search_skillsFull-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.
    get_skillFull 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.
    compare_toolsSide-by-side quality profiles for 2–5 tools by slug. Same fields as get_skill; ordering follows the request, not rank.
    list_collectionsThe curated buyer-intent collections (e.g. mcp-servers, testing-qa, browser-automation). Use get_collection for the ranked tools inside one.
    get_collectionQuality-ranked tools inside one curated collection. Critical-risk tools are excluded by default (risk_filter); every result carries risk_level and risk_reasons.
    demand_pulsePublic, 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.
