"Techniques for Scraping Dynamic Websites with JavaScript and Handling CAPTCHA or Proxy Issues" matching MCP servers:

Local stdio MCP server with six tools for browser verification detection, authorized provider test-key and owned image/text actions, and task resumption in an existing Playwright/CDP session. Includes four demos with server validation.

MCP server that gates API calls to AI agents using proof-of-work (free) or Lightning payment (3 sats), providing challenge, verify, and status tools for per-call authentication without accounts.

A client-side MCP proxy that injects OAuth 2.0 bearer tokens or API keys into MCP requests, enabling MCP clients to connect to OAuth/API-key-protected MCP servers like Amazon Bedrock AgentCore Gateway. It automatically fetches and refreshes credentials using AgentCore Identity or static values.

Implements a secure MCP server with API Key and JWT authentication, providing tools like echo, login, secure_action, and admin_action. Includes MCP Inspector integration for testing and debugging.

Enables fetching web URLs through authenticated residential egress with provider, country, and session controls. It also exposes tools for checking the exit IP, account status, and masked connection URL.

Enables connecting multiple accounts to remote MCP servers like Slack, Sentry, and Trello through a single OAuth-fronted proxy, with per-account URLs and token handling.

A wrapper for mcp-remote that provides secure authentication for protected MCP servers using Adobe IMS or Okta OAuth flows. It features automated token management, validation, and background refreshing for seamless access to remote resources.

A flexible, extensible framework for building MCP servers with API key authentication, user management, and dynamic tool sharing.

A self-hosted, OAuth-fronted MCP proxy that lets Claude custom connectors reach RapidAPI's MCP endpoints by injecting API credentials, with per-upstream tool filtering and rate limiting.

Enables AI assistants to solve CAPTCHAs using OCR text recognition, object detection, and slider position matching through the ddddocr library.

It's a safety middleware that can detect and intercept self-harm and criminal intent at 3 stages. It allows developers of chat-based platforms to configure webhook notifications and store encrypted information for prior mitigation of any such cases.

Authenticating reverse proxy for MCP servers providing credential isolation, OAuth2 token management, and composite tool aggregation.

Enables running a FastMCP server behind a Caddy reverse proxy that enforces bearer-token authentication, so MCP clients can access tools over HTTP only with a valid token.

Enables per-profile tool filtering and enforcement for one or more upstream MCP servers, exposing only allowed tools and rejecting blocked calls, with Streamable HTTP serving and observability.

The Execution Security Layer for the Agentic Era. Providing deterministic "Sudo" governance and audit logs for autonomous AI agents.

An MCP server that acts as a governance proxy for AI agents, evaluating each tool call against policies before execution, enabling secure and controlled access to systems like Slack, GitHub, and AWS without exposing credentials to the agent.

Acts as a secure OAuth 2.0/2.1 proxy gateway for MCP servers, enabling integration with Claude and ChatGPT platforms.

Enables secure MCP traffic by filtering threats with a 3-stage detection pipeline, applying RBAC policies, and redacting sensitive data in real-time via an SSE-inspecting proxy.

A self-hosted proxy that enables per-user credential injection for upstream MCP servers, allowing users to securely connect services like GitHub and Confluence via one-time links without exposing credentials to the LLM.

Enables connecting multiple remote HTTP MCP servers through a single local stdio endpoint, handling OAuth authentication, token refresh, and namespace-scoped tools.
