"Capture The Flag (CTF) cybersecurity competitions and challenges" matching MCP servers:

Enables human-in-the-loop interaction for AI coding workflows through native desktop dialogs that present route choices, text input, and image annotation capabilities when AI assistants encounter decision points.

Exposes common CTF and cybersecurity tools (crypto, forensics, malware analysis, steganography, reverse engineering, pwn, OSINT) so LLMs can help solve capture-the-flag challenges in a controlled lab environment.

Relays a result screenshot to Slack so you can review a coding agent's output without opening the app.

Feature flag service for A2A networks with DID-keyed targeting, percentage rollouts, and USDC settlement on Base L2.

A vulnerable MCP server designed for educational CTF challenges. It demonstrates various MCP security vulnerabilities in a controlled environment.

Enables access to 200 compressed cybersecurity career profiles via tools for listing, searching, and invoking careers, supporting SOC, IR, pentest, GRC, IAM, and more.

GDB Enhanced Features MCP server for remote debugging and CTF exploitation with 41 specialized tools including ROP search, format-string detection, and memory patching.

MCP server for screen recording on macOS, iOS Simulator, and Android, with key-frame extraction via ffmpeg, enabling AI agents to capture UI motion and transient visual states.

An MCP server that uses headless Chromium (Puppeteer) to capture pixel-perfect screenshots and extract DOM from URLs, with LLM-friendly step-based workflows.

Enables querying Latvian cybersecurity data, including regulations, guidelines, and advisories from CERT.lv, directly from any MCP-compatible client.

Query Estonian cybersecurity data -- regulations, decisions, and requirements from RIA/CERT-EE -- directly from any MCP-compatible client.

MCP server that enables semantic search over macroeconomic data using the Lambda Capture API.

Enables querying Maltese cybersecurity regulations, decisions, and requirements from CSIRTMalta via MCP-compatible clients like Claude and Cursor.

Enables querying Swedish cybersecurity regulations, decisions, and requirements from CERT-SE directly from MCP-compatible clients like Claude and Cursor.

Enables AI assistants to interact with macOS windows through yabai, providing window listing organized by Spaces and screenshot capture capabilities.

An MCP server that enables automating Capture One Pro on macOS, providing tools for reading and editing images, managing layers/masks, recipes, and processing with risk-tiered write gating.

Enables AI agents to drive TradingView Desktop, switch through a layout's symbols, and export each chart's rendered image, CSV data, and indicator details to local files, which they can then read in part or crop on demand. It runs jobs in a background process that does not consume agent tokens and keeps only the current day's output, leaving symbol choice, analysis, and use of the data to the caller.

Enables AI agents to extract video frames at configurable FPS and compose them into grid sheets for multimodal LLMs, with support for video download, HLS streams, and job management via MCP tools.

Enables querying Polish cybersecurity regulations, advisories, and frameworks from NASK/CERT Polska via Claude or any MCP-compatible client.

Enables searching the NIST NVD for CVEs, retrieving full CVE details, checking software for known vulnerabilities, and searching the CPE database.

Enables evidence-grade capture of web pages as screenshots, PDFs, or HTML, returning a signed artifact URL, SHA-256 digest, timestamp, and optional public evidence page for attestation.

A security-first MCP (Model Context Protocol) backend built with Node.js and Express, featuring hardening, rate limiting, structured logging, and Docker support.
