🔒 Security Audit Report - Context MCP Server

Date: 2025-11-08
Status: ✅ PASSED - NO CRITICAL SECRETS FOUND

Executive Summary

A comprehensive security audit of the Context MCP Server repository has been completed. No accidentally committed secrets, API keys, or sensitive credentials were found in the codebase or git history.

The repository follows security best practices with proper .gitignore configuration and environment variable management.

Audit Scope

✅ Files Scanned: All tracked files in git repository
✅ Git History: Full commit history searched for secret patterns
✅ Configuration Files: .env*, docker-compose.yml, settings.py
✅ Private Keys: SSH keys, SSL certificates, PGP keys
✅ Credentials: Database passwords, API keys, tokens

Findings Summary

1. API Keys and Tokens ✅ SECURE

Status: No real API keys found

Checked for:

  • OpenAI API keys (sk-*)
  • Google Gemini API keys
  • Qdrant API keys
  • GitHub tokens (ghp_*)
  • Other authentication tokens

Result: All API key references are:

  • Empty placeholders in .env.example
  • Environment variable references in code
  • Documentation examples with placeholder values

Files Reviewed:

  • .env.example - Empty placeholders only
  • deployment/docker/.env.example - Empty placeholders only
  • src/config/settings.py - No hardcoded keys
  • src/vector_db/embeddings.py - Reads from env vars only

2. Database Credentials ✅ SECURE

Status: No real database passwords found

Checked for:

  • PostgreSQL passwords
  • Database connection strings with embedded credentials
  • Redis passwords

Result:

  • .env.example contains placeholder: DATABASE_URL=postgresql://context:password@localhost:5432/context_dev
  • docker-compose.yml uses env var substitution: ${POSTGRES_PASSWORD:-password}
  • Default password "password" is clearly a placeholder for development only
  • .env file is properly in .gitignore (not tracked)

Files Reviewed:

  • .env.example - Placeholder credentials only
  • deployment/docker/docker-compose.yml - Env var references
  • src/config/settings.py - Default placeholder value

3. Private Keys and Certificates ✅ SECURE

Status: No private keys found

Checked for:

  • SSH private keys (id_rsa, id_ed25519)
  • SSL/TLS certificates and private keys
  • PGP/GPG private keys

Result: No private key files detected in repository

4. Configuration Files ✅ SECURE

Status: Proper .gitignore configuration

Tracked .env files:

  • ✅ .env.example - Tracked (contains only placeholders)
  • ✅ .env - NOT tracked (properly ignored)
  • ✅ .env.local - NOT tracked (properly ignored)
  • ✅ .env.production - NOT tracked (properly ignored)
  • ✅ deployment/docker/.env - NOT tracked (properly ignored)
  • ✅ deployment/docker/.env.backup - NOT tracked (properly ignored)

.gitignore Configuration:

  • Line 12: *.env - Ignores all .env files
  • Line 423-425: Explicit env file rules with exception for .env.example
  • Properly excludes sensitive files

5. Git History ✅ SECURE

Status: No secrets in commit history

Searched for:

  • Commit messages containing "secret", "password", "api_key", "token"
  • Actual secret patterns (sk-, ghp_, etc.)

Result:

  • Commits found with "secret" in message are about API key authentication features (not actual keys)
  • No real credentials in any commit
  • No accidentally committed .env files in history

Detailed Findings

✅ No Critical Issues Found

All environment variables are properly:

  1. Externalized - Stored in .env files (not tracked)
  2. Documented - .env.example shows what needs to be configured
  3. Referenced - Code reads from environment variables only
  4. Ignored - .gitignore prevents accidental commits

✅ Best Practices Observed

  1. Environment Variable Management

    • Pydantic Settings for configuration
    • Environment variable substitution in docker-compose.yml
    • No hardcoded secrets in code

  2. File Exclusions

    • .env files properly ignored
    • .gitignore is comprehensive
    • No sensitive files tracked

  3. Documentation

    • .env.example provides clear template
    • Comments explain what each variable is for
    • Placeholder values are obviously fake

Recommendations

✅ Current Status: SECURE

No immediate action required. The repository follows security best practices.

📋 Ongoing Best Practices

  1. Continue using .env.example for configuration templates
  2. Never commit .env files - Keep .gitignore rules in place
  3. Rotate credentials regularly if any are ever exposed
  4. Use environment variables for all sensitive configuration
  5. Review .gitignore before adding new configuration files

🔍 Monitoring

  • Continue scanning for accidental commits using pre-commit hooks
  • Consider using tools like git-secrets or truffleHog in CI/CD
  • Regular security audits (quarterly recommended)

Conclusion

✅ SECURITY AUDIT PASSED

The Context MCP Server repository is secure with no accidentally committed secrets or sensitive information. All credentials are properly externalized through environment variables, and the .gitignore configuration prevents accidental commits of sensitive files.

No git history cleanup required.
