A standalone MCP server for API testing and management, allowing AI assistants to interact with RESTful APIs through natural language. Postmancer is an MCP (Model Context Protocol) server that enables AI assistants like Claude to make HTTP requests, manage collections of API endpoints, and test API responses. It provides similar functionality to tools like Postman or Insomnia but designed specific
Version: 4.1.0 | License: MIT (open-core) Website & Docs: https://codeguardian.studio CCG stands out as the most comprehensive MCP server for Claude Code: Key Differentiators: - All-in-one: Guard + Metrics + Workflow + Memory in a single server - 113+ MCP tools: The most comprehensive toolset available - Session management: Resume work across conversations - Real-time progress: Track refactoring p
Master advanced prompt engineering techniques to maximize LLM performance, reliability, and controllability in production. Use when optimizing prompts, improving LLM outputs, or designing production prompt templates.
Optimize website and web application performance including loading speed, Core Web Vitals, bundle size, caching strategies, and runtime performance
Runtime debugging workflow with automated log collection. Use when fixing bugs that require runtime evidence (values, types, flow), when you'd otherwise ask user to "open DevTools, reproduce X, tell me what you see", or when bug depends on user interaction that can't be simulated. This skill automates log collection - logs are captured server-side and accessible programmatically.
Use when completing tasks, implementing major features, or before merging to verify work meets requirements
Teaches agents to iteratively build websites using Stitch with an autonomous baton-passing loop pattern
MCP Server for AI-powered video editing. Let Claude, GPT, or any AI agent edit videos through natural language. Add to your Claude Desktop config (claudedesktopconfig.json): Then restart Claude Desktop. You can now edit videos through conversation. Layer Compositing Model: Output: 1920x1080, 30fps, H.264 + AAC, MP4 atsurae.ai also exposes a REST API that any AI agent can call directly, without MCP
Implement comprehensive testing strategies using Jest, Vitest, and Testing Library for unit tests, integration tests, and end-to-end testing with mocking, fixtures, and test-driven development. Use when writing JavaScript/TypeScript tests, setting up test infrastructure, or implementing TDD/BDD workflows.
Database design principles and decision-making. Schema design, indexing strategy, ORM selection, serverless databases.
Create and manage Claude Code skills following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (keywords, intent patterns, file paths, content patterns), enforcement levels (block, suggest, warn), hook mechanisms (UserPromptSubmit, PreToolUse), session tracking, and the 500-line rule.
PC and console game development principles. Engine selection, platform features, optimization strategies.
Write, review, or improve SwiftUI code following best practices for state management, view composition, performance, modern APIs, Swift concurrency, and iOS 26+ Liquid Glass adoption. Use when building new SwiftUI features, refactoring existing views, reviewing code quality, or adopting modern SwiftUI patterns.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Use when building, extending, or debugging WordPress REST API endpoints/routes: register_rest_route, WP_REST_Controller/controller classes, schema/argument validation, permission_callback/authentication, response shaping, register_rest_field/register_meta, or exposing CPTs/taxonomies via show_in_rest.
Core component library and design system patterns. Use when building UI, using design tokens, or working with the component library.
You are an API mocking expert specializing in realistic mock services for development, testing, and demos. Design mocks that simulate real API behavior and enable parallel development.
This repo contains skills for Claude Code, Codex, and any agent that supports the SKILL.md standard. 1. Create a free account at app.lessie.ai — new accounts include trial credits 2.
