"Authy" matching MCP servers:

A secure MCP server that stores and retrieves API keys and credentials, featuring encrypted storage, masked retrieval, and AI-powered recommendation via MCP sampling.

A Model Context Protocol server that enables interaction with self-hosted Supabase instances, allowing developers to query database schemas, manage migrations, inspect statistics, and interact with Supabase features directly from MCP-compatible development environments.

Reference MCP servers that integrate with Autodesk Platform Services, demonstrating various authentication combinations and exposing tools to list projects and folder contents via the Data Management API.

It enables MCP clients to authenticate with short-lived SPIFFE JWT-SVIDs as OAuth client credentials, obtaining audience-bound access tokens for scoped tool calls without static API keys.

A FastMCP server template with full MCP authentication via Descope, designed for easy deployment on Render. It provides a foundation for building secure, authenticated MCP servers with scope-based access control.

Authenticates users via Google OAuth and returns the authenticated user's display name through the get_current_user tool. Supports deployment on Node.js and Cloudflare Workers.

Enables validating Microsoft Entra access tokens to determine whether an MCP caller is a signed-in user or only an application, illustrating MCP authentication methods.

Enables interaction with Twilio API services including messaging, voice, and Studio flows through Docker deployment. Supports both API Key and Auth Token authentication for managing calls, messages, phone numbers, and automation workflows.

A secure remote MCP server template implementing OAuth 2.1, client ID metadata documents, and constant-time credential verification for safe AI tool interactions.

Enables an MCP server with OAuth authentication, protecting tools like user CRUD operations behind session tokens obtained through a browser-based authentication flow.

Provides weather information from the National Weather Service API with full MCP OAuth 2.1 compliance, including weather alerts and forecasts for US locations through secure Azure AD authentication.

Minimal mock MCP server for testing authentication with dynamic API key and username/password, deployable on Vercel.

A template for building MCP servers that supports both HTTP transport with Bearer token authentication and stdio-based connections for local clients like Codex and Claude. It provides a foundational structure for practicing secure authentication and tool integration within the Model Context Protocol.

A MCP server that requires user authentication via Auth0, allowing it to call protected APIs on behalf of authenticated users.

An MCP authorization server implementing OAuth2/OIDC flows, supporting dynamic client registration, PKCE, consent screens, and client ID metadata documents for MCP authorization.

Enables MCP clients to pull live FX and crypto prices, store and read JSON records in a DynamoDB-backed key-value store, and run business calculations such as invoice totals, shipping estimates, and inventory-status checks. It runs over streamable HTTP on AWS Lambda with SigV4-authenticated access, or locally via stdio.

A production-ready MCP server with OAuth 2.1 authentication, enabling authenticated MCP tool calls via Google OAuth.

Remote MCP server for verifying API key authentication header propagation and debugging inbound HTTP headers.

A Cloudflare Workers-based MCP server implementation that supports OAuth login and bearer token authentication, allowing secure connection from MCP clients like Claude Desktop and the MCP Inspector.
