VibeCheck MCP Server
AI-powered security audit tool for codebases. Analyzes code for vulnerabilities using real-time data from MITRE CWE and npm audit.
Features
AI-Powered Analysis: Uses MCP sampling to analyze code with Claude
Real-Time CWE Data: Fetches vulnerability definitions from MITRE's CWE API
Dependency Scanning: Uses npm audit for package vulnerability checks
Zero Configuration: No API keys required to get started
Related MCP server: mcp-web-audit

scan_codebase
Full AI-powered security audit with real-time vulnerability data.
Analyzes:
Authentication and authorization issues
API security vulnerabilities
Database security rules
Exposed secrets and environment variables
Dependency vulnerabilities (via npm audit)
Data flow and injection vulnerabilities
Input:
{
"path": "/path/to/codebase",
"categories": ["auth", "api", "secrets-env"],
"severityThreshold": "medium"
}Or provide files directly:
{
"files": [
{ "path": "src/auth.ts", "content": "..." }
]
}Categories:
auth- Authentication, sessions, middlewareapi- API routes, endpointsdatabase-rules- Firebase/Supabase rules, Prisma schemassecrets-env- Environment variables, config filesdependencies- package.json vulnerabilitiesdata-flow- User input handling, injection points
check_dependencies
Quick dependency-only scan using npm audit.
Input:
{
"path": "/path/to/project",
"includeDevDependencies": false
}Requirements:
npm installed

File Reading: Reads files from the specified path or accepts file contents directly
Hotspot Collection: Categorizes files by security relevance (auth, api, secrets, etc.)
Dependency Audit: Runs
npm auditif package-lock.json existsAI Analysis: Uses MCP sampling to analyze each category with expert prompts
CWE Enrichment: Fetches relevant CWE definitions from MITRE API
Results: Returns structured findings with severity, CWE/OWASP refs, and remediation steps

Requirements:
npm must be installed
Directory must contain package-lock.json (or yarn.lock/pnpm-lock.yaml)
Inputs: path (required), includeDevDependencies.
scan_codebaseB
AI-powered security audit with real-time vulnerability database lookups.
Analyzes code for:
Authentication and authorization issues
API security vulnerabilities
Database security rules
Exposed secrets and environment variables
Dependency vulnerabilities (via npm audit)
Data flow and injection vulnerabilities
Returns findings with:
Severity ratings (critical, high, medium, low)
AI reasoning and confidence scores
CWE and OWASP references
Remediation steps
Inputs: path, files, categories, severityThreshold.

TDQS
Scored across 2 tools
The two tools have clearly distinct purposes: check_dependencies focuses specifically on npm dependency vulnerabilities using npm audit, while scan_codebase performs a broader AI-powered security audit across multiple code aspects. There is no overlap in scope or functionality.
Both tools follow a consistent verb_noun naming pattern (check_dependencies, scan_codebase) with clear action verbs describing their functions. The naming is uniform and predictable throughout the tool set.
With only 2 tools, this server feels severely under-scoped for its apparent purpose of security auditing. A comprehensive security toolset would typically include more operations like fixing vulnerabilities, monitoring, or configuration management. The count is too low for meaningful agent workflows.
While the tools cover vulnerability checking and code scanning, there are significant gaps in the security audit lifecycle. Missing are tools for remediation (e.g., fix_vulnerabilities, update_dependencies), reporting, configuration management, or continuous monitoring. This incomplete surface will limit agent effectiveness.
