Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed 5 months ago, and the latest version (2.5.3) reached the registry 5 months ago.

Use the MCPSkills pre-install trust layer from inside Claude Code, Cursor, or any MCP client.
13 standard signals (15 in Skills Mode) across 4 dimensions with safety scanning for prompt injection, credential theft, and supply chain attacks. Check install risk before an MCP server or AI skill reaches your agent.
claude mcp add mcpskills -- npx @mcpskillsio/server

list_packagesBrowse curated, pre-scored skill packages organized by use case.
"Show me safe AI skill packages for full-stack development"
get_badgeGenerate an SVG trust badge URL for your README.
"Get a trust badge for my repo anthropics/anthropic-sdk-typescript"
watch_repoStart monitoring a repo for trust score changes (requires API key).
"Watch modelcontextprotocol/servers for score changes"
check_watchedRe-scan all watched repos for score or tier changes (requires API key).
"Check my watched repos"
batch_checkScore up to 5 repos in a single call (Developer Pro or Team).
