auto-skill-connector

An MCP connector that gives Claude Code / Claude Desktop access to a database of ~200k scraped Claude skills, MCP servers, and plugins. Instead of building a capability from scratch, Claude can search this database mid-conversation, read a matching skill's instructions, and follow them immediately — or install it permanently as a real /skill.

It ships two tools:

• recommend_skill(task) — hybrid full-text + semantic search over the skill database. Returns the best match's full SKILL.md content (or a short list to pick from, if a few skills fit equally well).

• install_skill(url, name?) — downloads a skill's SKILL.md and saves it to ~/.claude/skills/<name>/SKILL.md, so Claude Code can invoke it as a normal skill from then on, in any project.

Query embedding happens server-side (Supabase Edge Function), so this connector only depends on mcp + httpx — no local ML runtime to install.

Install

Claude Code

claude mcp add auto-skill --scope user -- uvx --from git+https://github.com/neelavalareddy/auto-skill-connector auto-skill-mcp

Claude Desktop

Add this to your claude_desktop_config.json (Settings → Developer, or find it directly — on Windows it's usually under %APPDATA%\Claude\claude_desktop_config.json):

{
  "mcpServers": {
    "auto-skill": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/neelavalareddy/auto-skill-connector", "auto-skill-mcp"]
    }
  }
}

Restart Claude Desktop after editing the config.

Both require uv installed (uvx ships with it) — no cloning or manual pip install needed.

Automatic skill suggestions (optional, Claude Code)

Want every chat message checked against the database automatically? Add the included hooks/skill_suggest.py as a UserPromptSubmit hook: it runs on each prompt you send, and when a skill matches, Claude is told to fetch and apply it via recommend_skill. It fails open — errors and timeouts never block or slow your chat.

1. Download hooks/skill_suggest.py somewhere permanent (e.g. ~/.claude/hooks/skill_suggest.py).

2. Merge this into ~/.claude/settings.json (use an absolute path on Windows, e.g. C:\\Users\\you\\.claude\\hooks\\skill_suggest.py):

{
  "hooks": {
    "UserPromptSubmit": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "python",
            "args": ["~/.claude/hooks/skill_suggest.py"],
            "timeout": 10
          }
        ]
      }
    ]
  }
}

Running it directly

git clone https://github.com/neelavalareddy/auto-skill-connector
cd auto-skill-connector
pip install -e .
python mcp_server.py

How it works

The skill database lives in Supabase (Postgres + pgvector), populated by a separate scraper that continuously crawls GitHub, npm, and the MCP registry for Claude skills. This repo only contains the read-only connector — search queries hit a read-only anon key (RLS grants SELECT only; no writes are possible with it).
