MCP Vulnerability Reporting

Professional vulnerability report generator for security assessments. This MCP server creates standardized, well-formatted security reports following industry best practices.

⚠️ IMPORTANT: AI-Generated Content

This MCP does not use pre-written templates. Instead, the AI (Claude) generates all report content based on the specific vulnerability instance. The report structure follows the template format from /Users/orhanyildirim/Desktop/mcp-browser-injection-extented/report.md, but the content is dynamically created for each unique finding.

What the AI Generates:

• ✅ Vulnerability Overview (educational description of the vulnerability type)

• ✅ Specific Findings (detailed analysis of this instance)

• ✅ Steps to Reproduce (customized for the target application)

• ✅ Recommendations (actionable remediation guidance)

• ✅ Impacts (business and technical impact analysis)

• ✅ References (OWASP, CWE, security resources)

Example Workflow with Browser MCP

Here's how to use both MCPs together. Claude generates all report content:

User: "Test https://vulnerable-site.com/login for SQL injection and create a professional report"

Claude uses Browser MCP:
1. browser_navigate({ url: "https://vulnerable-site.com/login" })
2. browser_test_payload({
     targetSelector: "#username",
     payload: "' OR 1=1--",
     submitSelector: "#login"
   })
   // Returns: { isVulnerable: true, confidence: "high", detectedBehaviors: [...] }

3. browser_screenshot({ path: "./evidence/sqli-bypass.png" })

Claude uses Reporting MCP (AI GENERATES ALL CONTENT):
4. get_report_template()
   // Returns: Template with exact structure and formatting requirements

5. create_vulnerability_report({
     vulnerability: {
       type: "SQL_INJECTION",
       severity: "Critical",
       url: "https://vulnerable-site.com/login",
       parameter: "username",
       payload: "' OR 1=1--",
       method: "POST"
     },

     // AI WRITES THIS OVERVIEW:
     overview: "SQL Injection is a code injection technique that exploits security vulnerabilities in an application's database layer. This vulnerability occurs when user-supplied input is incorporated into SQL queries without proper sanitization...",

     findings: {
       // AI WRITES THIS SPECIFIC DESCRIPTION:
       specificDescription: "The login form at /login endpoint is vulnerable to SQL injection via the username parameter. The application directly concatenates user input into SQL queries without using parameterized statements...",
       detectedBehaviors: ["SQL_ERROR_MESSAGE", "AUTHENTICATION_BYPASS"],
       confidence: "high"
     },

     // AI GENERATES THESE STEPS:
     stepsToReproduce: [
       "Navigate to https://vulnerable-site.com/login",
       "In the username field, enter: ' OR 1=1--",
       "In the password field, enter any value",
       "Click the login button",
       "Observe successful authentication bypass",
       "Verify by checking session cookie"
     ],

     // AI WRITES THESE RECOMMENDATIONS:
     recommendations: [
       "- **Use Parameterized Queries**: Implement prepared statements with parameterized queries for all database interactions...",
       "- **Input Validation**: Implement strict server-side input validation...",
       "- **Principle of Least Privilege**: Configure database accounts with minimal permissions..."
     ],

     // AI WRITES THESE IMPACTS:
     impacts: [
       "- **Complete Authentication Bypass**: An attacker can bypass the login mechanism entirely...",
       "- **Sensitive Data Exfiltration**: Using UNION-based attacks, attackers can extract database contents...",
       "- **Database Manipulation**: Attackers could modify or delete records..."
     ]
   })

6. add_evidence_to_report({
     reportId: "vuln_report_xxx",
     evidenceType: "screenshot",
     content: "./evidence/sqli-bypass.png",
     description: "Authentication Bypass - Successfully logged in as admin"
   })

7. calculate_cvss_score({ reportId: "vuln_report_xxx" })

8. export_report({
     reportId: "vuln_report_xxx",
     outputPath: "./reports/sql-injection-login-bypass.md"
   })

See USAGE_EXAMPLE.md for a complete detailed example.

Report Format

Reports follow the exact template structure from /Users/orhanyildirim/Desktop/mcp-browser-injection-extented/report.md:

## Vulnerability Overview
[AI-generated general description of vulnerability type]

### Finding Details
[AI-generated specific findings for this instance]

### Steps To Reproduce
1. [AI-generated step]
2. [AI-generated step]
...

## Recommendations
To address this finding, implement the following:
[AI-generated recommendations with bold headers]

## References
See the following for more information:
[AI-generated or template default references]

## Impacts
If not addressed, this finding could lead to the following:
[AI-generated impacts with bold headers]

How It Works

1. Template Loading: MCP reads report.md template from its directory

2. AI Reads Template: Use get_report_template() to see the exact structure required

3. Template Structure: The markdown format is fixed and matches your report template exactly

4. AI Content: Claude generates all descriptive content based on:

   • The specific vulnerability found during testing

   • Security best practices and industry standards

   • Context from the target application

   • Severity and confidence levels

   • Template format guidelines

5. Flexibility: Content adapts to different vulnerability types, applications, and contexts

6. Fallback References: If AI doesn't provide custom references, the vulnerability database provides defaults for common types (SQL Injection, XSS, SSTI, Command Injection, NoSQL, LDAP, XXE)

Development

# Run in development mode
npm run dev

# Build for production
npm run build

# Run production build
npm start

Architecture

• index.ts: Main MCP server implementation

• vulnerability-db.ts: Vulnerability knowledge base with templates

• dist/: Compiled JavaScript output

Integration with Browser Automation MCP

This MCP is designed to work seamlessly with the mcp-browser-injection-extended MCP server. The browser MCP handles:

• Automated vulnerability testing

• Payload generation and testing

• Evidence collection (screenshots, HTTP responses)

The reporting MCP then transforms those findings into professional security reports.
