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

Enables MCP clients to read bounded workspace files, validate exact replacement plans for the VS Code extension, and check recent typing progress without modifying source or running shell commands.

An MCP server that gives LLM clients access to a SQL Server database and the local filesystem, including file operations and image handling.

Enables document conversion between PDF, DOCX, and Markdown formats to facilitate reading and editing complex files in AI tools like Claude Desktop or Cursor. It utilizes marker-pdf and pandoc to provide structured text versions of documents, helping to manage context and support unsupported file types.

A Model Context Protocol (MCP) server for ZeroDrive file management. It enables AI assistants like Claude to interact with ZeroDrive cloud storage through a standardized interface.

Enables AI clients to securely execute remote commands and transfer files over SSH through standardized MCP tools, with multi-host management, flexible authentication, and an admin console.

TheWeave is a markdown-native memory architecture for Claude and any MCP-aware agent. Your agent's memory lives as plain .md files you own: a 5-verb MCP core over the vault, query-driven PageRank retrieval, bi-temporal facts (valid_from / valid_until), and a persona-as-vault model. No database and no embeddings server. The files are the memory, inspectable in your editor and versionable in git.

A local MCP server that wraps common forensic command-line tools for CTF/forensics competitions into MCP tools, enabling automated analysis of disk images, memory dumps, network captures, SQLite databases, archives, and steganography.

Combines KC Chat Panel session interaction with AgentDock computer control tools, enabling Cursor Cloud Agent to chat and operate the local machine via AgentDock.

A production-grade Model Context Protocol server that enables secure management of context data through a React dashboard, supporting ZIP processing, context approval workflows, and system monitoring.

Enables AI agents and users to manage workspace files, monitor system metrics, take persistent notes, and retrieve weather data via MCP tools and resources.

Enables coding agents to use an Obsidian vault as long-term memory, with search, reading, and writing of notes, plus automatic capture of learnings that are propagated to MOCs, daily notes, and the knowledge index with git commits.

locidx

Enables an agent to read the user's local Messages.app database on macOS, listing chats and threads and searching iMessage/SMS history entirely on localhost, with optional AppleScript sending gated behind an explicit flag. Access is read-only and scoped-shut by default, and replies can be optionally sent when send mode is enabled.

Compares a project's .env file against its .env.example template to surface missing, extra, and empty keys, flag empty required variables, and produce paste-safe key inventories for tickets or sharing. Runs entirely on local files with every value redacted, so secrets are never echoed or uploaded.

Exposes a Traktor collection's reconciliation over stdio, enabling an MCP client to report status, preview entry-by-entry changes, repoint or add entries, and purge records whose files are gone. Writes are backed up and gated behind an explicit apply flag, with dry-run planning available first.

A Model Context Protocol server that provides development and debugging tools for Expo-based React Native applications, enabling developers to manage Expo servers, capture logs, and manipulate project files.

A local-first MCP server that lets an AI assistant log the clothes you own in a single JSON file and then suggest weather- and occasion-appropriate outfits, flag unworn items, triage a donate bag, and build multi-day packing lists with gap warnings. Everything stays on your machine, with predictable scoring rules instead of shopping feeds or trend pressure.

MCP server for remote execution on Windows devices. Enables Codex to run PowerShell, manage files/processes, and capture screenshots via a relay and enrolled Windows agent.

Provides comprehensive computer control capabilities including shell commands, file operations, screen capture, keyboard/mouse input, window management, clipboard access, and system monitoring following the OODA loop pattern.

Enables AI agents to capture, structure, remember, and retrieve source-backed memory as local Markdown files, with reviewable writes and no cloud dependency.

Enables AI agents to automate a Linux desktop natively on Wayland, with 68 tools for screen capture, input simulation, browser automation, OCR, accessibility, media, audio, clipboard, notifications, filesystem, system, memory, and network operations through the MCP protocol.

An embedded MCP server for Cocos Creator that enables AI assistants to inspect and operate running Cocos projects through tools like execute_javascript, get_project_info, and screenshot capture.

Enables Claude to capture structured, schema-validated notes into a personal Obsidian vault's inbox and later recall them through ranked keyword search, recency listing, and single-note reading, with reads confined to the vault and no edit or delete access.

Enables MCP-compatible agents to control an Android device over the network via ADB, providing tools for shell commands, screen capture, UI inspection, file operations, and input simulation.

Provides eight scoped, read-only tools for health checks and for finding, searching, reading, listing, traversing, grepping, and globbing a configured user's native memories and personal-context subtree, without exposing capture or write operations.

Enables Claude Desktop to add, retrieve, update, delete, and list notes kept in a JSON file, with the notes path configurable via an environment variable or CLI flag. Notes are persisted with atomic saves behind a write lock, and missing notes raise errors rather than returning placeholder text.

An MCP server that connects Claude to Google Sheets for enhanced brainstorming and structured data output, enabling seamless capture, organization, and manipulation of ideas directly within spreadsheets.

A Windows-local MCP server for capturing screenshots (full screen, displays, regions, active window) and managing capture images via deletion tools, using a .NET tool interface.

A local MCP server that lets Claude, Cursor, or Codex drive TruePath Recorder — start/stop recordings, list capture sources, and get the saved file path back. Local bridge over 127.0.0.1 + per-launch token; recordings never leave your Mac.

An MCP server that wraps Android ADB functionality into AI assistant tools, enabling device management, shell execution, file operations, app management, media capture, and log analysis via natural language.
