mcp-gui-tester Alternatives

mcp-agent-tester is an open-source tool for inspecting, testing, and running MCP servers and agents. It provides both a web UI and CLI, supports JSON trace export, and is designed for developers working with Model Context Protocol agents and infrastructure.

Simple MCP Client to quickly test and explore MCP servers from the command line

mcp-builder-toolkit is an open-source CLI utility that generates Python MCP server projects based on manifest files. It streamlines the process of creating readable and tested server code, making it easier for developers to scaffold and maintain MCP-compliant services.

Test your MCP server like you test an API — declarative YAML, CI-ready, zero boilerplate.

mcp-tool-auditor is an open-source command-line tool designed for security researchers to scan and pentest MCP servers. It provides both defensive scanning and offensive pentesting capabilities, mapping to the OWASP MCP Top 10. The tool helps identify and mitigate security vulnerabilities in AI and LLM-related infrastructures.

mcp-checkup is an open-source CLI utility that audits MCP server setups, measuring context tax and hygiene. It helps AI infrastructure engineers and developers ensure their Model Context Protocol servers are efficient and healthy by providing detailed health checks and token analysis.

mcp-strike is an open-source command-line tool designed for active, runtime adversarial testing of Model Context Protocol (MCP) servers. It helps security engineers and red teams identify vulnerabilities and weaknesses by simulating attacks and scanning for issues. The tool supports automated security assessments and is freely available under the MIT license.

mcp-server-remote is an open-source Python package that implements a remote MCP server for serving MCP clients. It is designed for developers who require MCP protocol support in their applications and can be run via the command line.

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.

Linter for MCP (Model Context Protocol) config files used by Claude Desktop, Cursor, Cline, Windsurf, and Zed. CLI + library API.

Enhanced MCP server for interactive user feedback and command execution in AI-assisted development, featuring dual interface support (Web UI and Desktop Application) with intelligent environment detection and cross-platform compatibility.

CI gate for MCP servers

mcpvet is an open-source CLI tool that combines testing, linting, and contract validation for MCP servers. It integrates with pytest and ESLint, streamlining the development and quality assurance process for developers working with the Model Context Protocol.
