"Simple MCP example using HTTP transport" matching MCP servers:

Enables LLMs to make HTTP requests with OAuth2, session cookies, retry logic, and cURL command generation, while providing security features like SSRF protection and TLS enforcement.

Enables users to analyze HTTP response headers of any URL for security and configuration, returning a 0-100 security score, HSTS/CSP and header checks, server detection, caching details, and recommendations. Supports pay-per-call access via x402 micropayments.

A thin MCP server wrapper that automatically audits all tool calls via Attestive's AuditClient, logging decisions and enabling verification of the hash chain. It provides an example server with audited tools and demonstrates end-to-end recording and verification through the MCP protocol.

Minimal template MCP server with OAuth login and example tools for building custom servers on the Connext platform.

Rate-limits MCP tool calls with Upstash Redis, allowing a configurable number of invocations per sliding window and sharing counters across server instances.

Reference implementation for adding subscription-based gating to MCP endpoints, covering auth, plan entitlements, usage metering, and multi-tenant scoping.

MCP server for end-to-end encrypted secret storage and retrieval, enabling LLM agents to fetch secrets by name via one-time URLs while keeping plaintext out of model context and logs.

Analyze and score HTTP security headers (CSP, HSTS, CORS, cookies) with actionable fix recommendations for web applications.

An MCP server template with built-in OAuth 2.0 authorization code flow and PKCE, enabling Grok to authenticate and invoke tools such as hello and publish_page.

A minimal, well-commented MCP server that authenticates its callers with Microsoft Entra ID (Azure AD).

Enables an MCP server to enforce External Verifier Contract authorization before proxied tool calls, allowing or denying requests based on a supplied bundle.

Deterministic pre-execution safety certification for autonomous AI agents. Evaluates proposed actions across scope, reversibility, and sensitivity constraints — returns Certified, Warning, Escalate, or Blocked decisions with cryptographic audit trails. 3 tools: certify_action, check_budget, get_certification_history. Built on the QAE Safety Kernel (Rust + PyO3 bindings, pip install qae-safety).

Demonstrates Agent Passport System pre-dispatch authorization by issuing one-use grants and verifying signed authorization envelopes before proxied tool calls reach the upstream server.

Demonstrates a FastMCP server with Bearer token authentication via Nginx and fine-grained authorization via Envoy and OPA.

A minimal example MCP server using Express and Clerk for authentication, exposing a streamable HTTP endpoint for MCP clients.

Demonstrates OAuth2/OIDC authentication for MCP servers using Asgardeo, with JWT validation and a sample weather tool to showcase secured API access.

A template for building MCP servers with optional per-tool authentication using WorkOS AuthKit and Vercel MCP adapter.

Demonstrates how to secure an MCP server with OAuth 2.1 using AWS Cognito, with support for dynamic client registration and client ID metadata documents.

Enables network security scanning using Nmap through MCP protocol. Supports quick port scans, full port scans with service detection, and custom Nmap commands with async task management.

An MCP server demonstrating OAuth 2.1 authentication with Scalekit, enabling per-user identity in MCP tools through JWT verification.
