mcpfuzz is an open-source command-line tool for dynamically scanning Model Context Protocol (MCP) servers. It actively probes live servers with exploit payloads to identify vulnerabilities, supporting security researchers and penetration testers in automating MCP server assessments.
mcp-fence is an open-source CLI tool for security scanning, protocol inspection, dynamic fuzzing, and sandboxed testing of Model Context Protocol (MCP) servers. It helps AI infrastructure engineers identify vulnerabilities and generate security reports.
Test your MCP server like you test an API — declarative YAML, CI-ready, zero boilerplate.
pcp-mcp is an open-source MCP server designed for use with Performance Co-Pilot (PCP). It facilitates advanced monitoring and integration using the Model Context Protocol, making it suitable for system administrators and developers managing performance data.
Prufa is an AI-powered quality assurance tool designed to audit web applications for critical failures in key user flows such as signup, login, and checkout. It addresses the problem of undetected breakages that can silently disrupt core functionality after a deployment, often resulting in lost sales or user frustration before teams become aware of the issue. By running these flows in a real browser immediately after each deploy, Prufa provides rapid feedback on what is broken, helping teams catch issues before customers do. The platform operates by executing end-to-end tests on live sites, simulating real user actions in the browser. It verifies each step of essential flows, such as form submissions, redirects, HTTP status codes, and beacon events, using deterministic code to confirm expected outcomes. , a redirect returning a 404 instead of a 200), and advisory findings, which are flagged by a large language model as potential UX concerns or antipatterns that may warrant human review but are not classified as definitive failures. This clear separation ensures users can distinguish between confirmed bugs and softer usability issues. After integrating Prufa with a site, every push to the main branch triggers automated re-testing of these flows via a deploy webhook. When a previously passing flow fails, the tool sends an alert—such as a Slack notification—with a screenshot and a detailed step trace highlighting what broke and when. Prufa also features "Gremlin mode," which subjects money flows to adversarial conditions by mutating inputs and exploring edge cases, revealing bugs that standard tests may miss. Each chaos run highlights the most valuable finding, such as failures triggered by unusual input formats or edge-case behaviors. Prufa offers a free audit without requiring signup or credit card details, allowing users to experience its capabilities immediately. It is delivered as a web-based service, with reports accessible directly in the browser. The tool is positioned as an AI QA engineer for web products, focusing on automated, post-deploy verification of critical user journeys.
