Key features: - MCP Server Tester — Connect any remote MCP server and run tool calls directly from your browser - MCP Client Tester — Test and debug MCP client connections against live servers - MCP Security Scanner — 27+ automated checks across authentication, transport security, injection risks, CORS, and rate limiting. Identifies exposed servers, missing auth, and misconfigured headers - MCP Server Registry — Searchable directory of 10,000+ MCP servers across databases, dev tools, productivity, and cloud services - Prompt Library — Curated prompts for working with MCP tools and AI agents - Developer Blog — 65+ in-depth guides on MCP development, security, authentication, and automation workflows Used by AI engineers, DevOps teams, and developers building with Anthropic Claude, Cursor, Windsurf, VS Code, and other MCP-compatible clients. As of 2026, over 8,000 MCP servers are publicly exposed with no authentication — MCP Playground's security scanner helps developers find and fix these issues before they become incidents. Free to use. No sign-up required.

Memory Validator

Memory Validator is a memory leak detector for use by software developers, software quality assurance testers and customer support staff using .Net, .Net Core (C#, VB.Net, etc) and native language compilers (C, C++, Delphi, VB6, Fortran etc). Use Memory Validator to: o Monitor billions of allocations in your application. o Detect memory leaks and handle leaks (GDI leaks, etc). o Find memory and handle leaks in native, .Net and mixed-mode .Net applications. o Find double deletes, double frees, calls to deleted objects and related memory errors. o Find uninitialized memory in C++ objects. o Automatically detect memory leaks using the command line API. (For use with Jenkins, etc). o Improve your unit tests, smoke tests and regression tests by automatically adding memory leak support to the tests.

PENTESTON

PENTESTON is an easy to use platform that can test network devices, custom web applications, and internet telecommunication devices for security bugs and flaws that affect integrity, confidentiality, or system availability.

Performance Validator

Performance Validator is a performance profiler for use by software developers and software quality assurance testers using .Net, .Net Core (C#, VB.Net, etc) and native language compilers (C, C++, Delphi, VB6, Fortran etc.). Use Performance Validator to: o Identify slow (time-consuming) functions in your application. o Identify busy (called very often, not necessarily slow) functions in your application. o View application behaviour in real-time. Improve your software quality testing with interactive profiling displays. o Create profiling reports with collapsible call trees and call graphs to share with your team on your intranet. o Automatically profile your software using the command line API. (For use with Jenkins, etc.). o Improve your unit tests, smoke tests and regression tests by automatically adding profiling support to the tests.
