Mcpskills

[MCP Skills — the pre-install trust layer for MCP servers and AI skills]

@mcpskillsio/server

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.

[npm version] [MCP Registry] [License: MIT]

[Add to Cursor] [Install in VS Code]

"Get a trust badge for my repo anthropics/anthropic-sdk-typescript"

watch_repo

Start monitoring a repo for trust score changes (requires API key).

"Watch modelcontextprotocol/servers for score changes"

check_watched

Re-scan all watched repos for score or tier changes (requires API key).

"Check my watched repos"

batch_check

Score up to 5 repos in a single call (Developer Pro or Team).

Full Reports

Free tier returns trust tier + dimension scores (same as mcpskills.io free scans, 10/day).

For full reports (13 standard / 15 Skills Mode signals + safety findings) inside your IDE, set your API key:

export MCPSKILLS_API_KEY=your_key_here

Get your API key at mcpskills.io/api. Developer Pro is $19/mo or $149/yr. Team is $99/mo for org/security workflows.

How It Works

The server calls the mcpskills.io trust scoring API, which:

1. Fetches repo data from GitHub API and OpenSSF Scorecard
2. Scores 13 standard signals across 4 dimensions (Alive, Legit, Solid, Usable)
3. Detects AI skills/MCP servers and activates Skills Mode (+2 bonus signals — 15 total)
4. Runs 5 safety scans based on ClawHavoc and ToxicSkills attack patterns
5. Assigns a trust tier: Verified (>=7.0), Established (>=4.5), New, or Blocked
