Secure Your AI with Security MCP Servers
Connect HashiCorp Vault MCP, 1Password MCP, and OAuth MCP to Claude. Secure secrets management, authentication, and vulnerability scanning for enterprise AI workflows.
SentinelMCP
SentinelMCP empowers Python and JavaScript developers to scan repositories for security risks. Run scan_secrets to uncover hardcoded API keys and tokens, check_dependencies to audit requirements.txt or package.json for vulnerabilities, analyze_code_security for insecure patterns, and validate_input for unsafe handling. Aggregate results into a scored security_summary for PR reviews or CI/CD pipelines.
dev-crypto-toolkit
Delivers utilities for JWT token decoding, data hashing, UUID generation, password processing, Base64 encoding/decoding, and timestamp manipulation. Backend developers and security engineers apply these for token validation, secure credential storage, unique record identification, and data transmission in web services.
DNS Health Scanner
Complete DNS and email security audit for any domain. Runs 13 checks (SPF, DKIM, DMARC, MX, SSL, DNSSEC, CAA, Blacklist, BIMI, MTA-STS, TLSA/DANE, Reverse DNS, Mail Ports) and returns a scored report (0-100, Grade A-F) with actionable fix instructions.
code-security-scanner
Scans source code for security vulnerabilities including SQL injection, XSS, insecure dependencies, and misconfigurations. Developers and security engineers integrate it via MCP to check files, directories, or repositories before commits or deployments. Supports automated analysis in CI/CD pipelines and code review processes.
Proposal Compliance Verifier MCP
Verifies proposal documents against compliance standards and regulations through MCP-accessible checks. Scans for missing sections, formatting errors, and rule violations programmatically. Suited for compliance officers, proposal managers, and legal teams in regulated sectors like government contracting and finance.
Smart Contract Scanner
Scans smart contracts for 13 vulnerability types and generates risk scores to assess severity. Blockchain developers and security auditors use it to detect issues like reentrancy or access control flaws in Solidity code. Applies in pre-deployment audits and CI/CD pipelines for automated security checks.

Security Best Practices
- • Least privilege: Grant only the permissions needed for the task
- • Short-lived tokens: Use tokens with expiration rather than long-lived credentials
- • Audit logging: Enable logging on both the MCP server and secrets manager
- • Separate environments: Use different credentials for dev, staging, and production
- • Rotate regularly: Set up automatic credential rotation where possible
- • Review access: Regularly audit which MCP servers have access to what secrets

Frequently Asked Questions
How do I securely manage API keys with MCP?
Use a security MCP server like 1Password MCP or Vault MCP to store and retrieve API keys. Never hardcode credentials. MCP servers can fetch secrets at runtime from secure stores, keeping your configuration files clean.
Can Claude access secrets from Vault?
Yes! Install the Vault MCP server, configure your Vault address and authentication method, and add it to Claude Desktop. Claude can then securely retrieve secrets using natural language requests.
What is the best MCP server for authentication?
For secrets management, 1Password MCP and Vault MCP are top choices. For OAuth flows, use the OAuth MCP server. For enterprise SSO, consider Auth0 MCP or Okta MCP servers.
How do I connect 1Password to Claude Desktop?
Install 1Password MCP server from the official 1Password developer portal. Configure your 1Password account credentials and add the server to your Claude Desktop MCP configuration. Restart Claude to activate.
Is it safe to use MCP servers with sensitive data?
Yes, when properly configured. Use read-only access, limit scope to specific secrets, enable audit logging, and prefer short-lived tokens. Security MCP servers like Vault and 1Password have enterprise-grade security built-in.
How do OAuth MCP servers work?
OAuth MCP servers handle the complete OAuth 2.0 flow — authorization, token exchange, and refresh. They support PKCE for security and can manage tokens for multiple providers, letting Claude authenticate to APIs on your behalf.
