Vigile

MCP server for Vigile AI Security — query trust scores for MCP servers and agent skills directly from your AI coding assistant.

Works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and any MCP-compatible client.

Installation

Claude Desktop

Add to your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "vigile": {
      "command": "npx",
      "args": ["-y", "vigile-mcp"]
    }
  }
}

Claude Code

claude mcp add --transport stdio vigile --scope user -- npx -y vigile-mcp

Or add to your project's .mcp.json:

{
  "vigile": {
    "command": "npx",
    "args": ["-y", "vigile-mcp"]
  }
}

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "vigile": {
      "command": "npx",
      "args": ["-y", "vigile-mcp"]
    }
  }
}

VS Code (Copilot)

Add to .vscode/mcp.json in your project:

{
  "servers": {
    "vigile": {
      "command": "npx",
      "args": ["-y", "vigile-mcp"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "vigile": {
      "command": "npx",
      "args": ["-y", "vigile-mcp"]
    }
  }
}

Global Install (Alternative)

npm install -g vigile-mcp

Then replace "command": "npx", "args": ["-y", "vigile-mcp"] with "command": "vigile-mcp" in any config above.

What It Does

Vigile scans and scores MCP servers and agent skills for security issues like tool poisoning, data exfiltration, prompt injection, and supply chain attacks. This MCP server brings those trust scores into your AI workflow — so your coding assistant can check whether a tool is safe before using it.

Covers servers from npm, Smithery, PyPI, and other registries, plus agent skills from Claude Code, Cursor, OpenClaw/ClawHub, and more.

Tools

Tool	Description
vigile_check_server	Look up trust score for an MCP server by name or package
vigile_check_skill	Look up trust score for an agent skill (claude.md, .cursorrules, OpenClaw skills, etc.)
vigile_scan_content	Scan raw content from a claude.md, .cursorrules, skill.md, or similar file for security issues
vigile_search	Search the Vigile trust registry by keyword
vigile_verify_location	Verify whether a skill uses location data safely and check for location-based attack patterns

Example Usage

Once installed, your AI assistant can use these tools naturally:

"Check if @anthropic/mcp-server-filesystem is safe" "Scan this claude.md file for security issues" "Search for database MCP servers and show me their trust scores"

Trust Scores

Vigile rates every server and skill on a 0-100 scale:

Score	Level	Meaning
80-100	Trusted	No significant issues found
60-79	Caution	Minor issues, review recommended
40-59	Risky	Notable security concerns
0-39	Dangerous	Critical issues, do not use

Authentication

By default, vigile-mcp uses the public Vigile registry (rate-limited). For higher limits, set your API key:

{
  "mcpServers": {
    "vigile": {
      "command": "npx",
      "args": ["-y", "vigile-mcp"],
      "env": {
        "VIGILE_API_KEY": "vgl_your_key_here"
      }
    }
  }
}

Get an API key at vigile.dev.

Rate Limits

Tier	Scans/min	Monthly Quota
Free (no key)	10	50
Pro ($30/mo)	60	1,000
Pro+ ($100/mo)	300	5,000

Registry lookups (vigile_check_server, vigile_check_skill, vigile_search) do not count against your scan quota. Only vigile_scan_content consumes scans.

Requirements

• Node.js 18+
• An MCP-compatible client
