Every x402, MPP, MCP, and skill listing we've indexed, normalized, and enriched.
n8n Workflow Webhook Bridge
Builds integration handoffs around n8n primitives like the Webhook node, HTTP Request node, and execution data inspection. Great for connecting event sources, transforming payloads, and making low-code workflows behave more like reliable integration middleware.
n8n-nodes-mcp Community Node for Model Context Protocol Workflows
n8n-nodes-mcp is a real n8n community node that lets self-hosted n8n instances connect to Model Context Protocol servers. This skill covers installing the package, configuring MCP transports inside n8n, and using the node in automation workflows that need external tools and struc
n8n GitHub Issue-to-Jira Ticket Automator
Deploys an n8n workflow via the n8n REST API using the GitHub Trigger node to capture new issue events and transform them into Jira tickets via the Jira Cloud REST API. Labels, priority mappings, and assignee routing rules are configured using n8n's Function node with custom Java
MySQL Query Agent
The open catalog of AI agent skills — 2,000+ security-scanned skills for Claude Code, Cursor, Codex, and more.
Mux Node SDK for Video and Streaming API Workflows
An ASE skill built around the official Mux Node SDK for working with Mux Video and Mux Data from JavaScript or TypeScript. It fits agent workflows that need programmable video uploads, asset lifecycle control, playback setup, webhook-aware automation, and analytics integration.
Mustache Template Renderer
Renders Mustache logic-less templates with partials resolution and lambda support. Uses the mustache.js library for client and server-side rendering with custom delimiter configuration.
Multi-Axis Code Review and Quality Gates
Run a structured pre-merge review across correctness, readability, architecture, security, and performance instead of relying on a shallow spot check.
MSW API Mocking Skill for Frontend and Integration Tests
Use this skill when an agent needs to stand up request handlers with Mock Service Worker, isolate network behavior in local development or tests, and keep mocks faithful to real endpoints. It is a task-focused mocking skill built around MSW, not a generic product card.
Microsoft Outlook Mail Sorter
Automatically triages Microsoft Outlook emails using the Microsoft Graph API /me/messages endpoint. Applies intelligent categorization with customizable rules and moves messages to appropriate folders.
Microsoft Outlook Calendar Sync Agent
Synchronizes calendar events bidirectionally using the Microsoft Graph API /me/calendar/events endpoint. Handles delta queries with deltaToken for incremental sync, manages recurrence patterns, and resolves timezone conflicts.
MoviePy Python Video Editing Library
MoviePy is a Python library for video editing — cuts, concatenations, title insertions, compositing, and custom effects. It reads and writes all common audio and video formats including GIF, powered by FFmpeg under the hood.
Moonshine Voice On-Device Speech Recognition and Voice Commands
Moonshine Voice is a fast on-device speech recognition library for interactive voice applications. This skill helps agents install the Python package, load supported language models, transcribe live microphone input, and wire transcript events into local voice-command workflows.
Monolith Web Page Archiver and Single-File Bundler
Monolith is a CLI tool and Rust library that saves complete web pages as a single HTML file by embedding CSS, images, JavaScript, and fonts as data URLs. It produces self-contained HTML5 documents that render correctly offline without external dependencies.
Monitor coding-agent token spend with Splitrail
Track token burn, spend, and model mix across multiple coding-agent tools from one local monitoring workflow.
Monitor Claude Code and Codex local usage logs for spend, model mix, and session burn with ccusage
Use ccusage when an agent operator needs to turn local Claude Code or Codex usage logs into spend and usage reports instead of manually reading raw JSONL files.
MongoDB MCP Server
The open catalog of AI agent skills — 2,000+ security-scanned skills for Claude Code, Cursor, Codex, and more.
MongoDB MCP Server for Database and Atlas Management
The official MongoDB MCP server connects AI agents to MongoDB databases and Atlas clusters through the Model Context Protocol, enabling structured queries, collection management, Atlas API operations, and aggregation pipelines with built-in authentication and access control.
Mods AI-Powered Command-Line LLM Interface by Charmbracelet
Mods is a CLI tool by Charmbracelet that pipes stdin directly to large language models. It enables AI-powered text processing, code review, commit message generation, and data transformation from the terminal with support for OpenAI, Anthropic, and local models.
Model user behavior and run distributed load tests before backend changes face real traffic with Locust
Script realistic user flows in Python and fan them out across workers so agents can pressure-test services before rollout.
Mockoon Local Mock API Server and CLI for API Development
Mockoon is the fastest way to run mock REST APIs locally. It provides a desktop application and a CLI for creating mock API servers with dynamic response templates, proxy mode, OpenAPI import, and request logging — no account required, fully open source.
Mock AI app dependencies for deterministic local and CI tests
Use AiMock when an agent needs reproducible tests around LLM APIs, MCP tools, A2A flows, vector stores, search, or moderation services without depending on live providers.
MLT Multimedia Framework for Video Editing and Processing
MLT is an open-source LGPL multimedia framework designed for video editing. It provides a toolkit and the melt command-line tool for non-linear video editing, transitions, effects, and rendering. MLT powers Shotcut, Kdenlive, and other video editors.
