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

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

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.

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

Cybersecurity AI - MCP server providing AI-powered tools and automation by MEOK AI Labs

Enables BM25 lexical search over a user-provided corpus of CTF writeups or technical documents through an MCP tool, returning relevant results with optional category and solved filters. It can run locally over stdio or as a centralized HTTP service shared by multiple MCP clients.

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.

Enables AI agents to look up and assess credit risk for England & Wales companies, searching by name, retrieving R-Scores with financials, charges, CCJs and directors, fetching verified contacts, and batch-enriching up to 50 companies per call.

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

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

Enables MCP-capable agents to add, search, edit, archive, and delete locally stored notes over streamable HTTP without using the web UI.

A Windows MCP server that enables AI agents to capture screenshots of open windows or the full desktop via stdio or HTTP.

Enables vulnerability analysis by querying CVE data through the CIRCL API and provides professional security risk assessments for SOC and Blue Team operations. It integrates tools for searching vulnerabilities with resources like risk matrices and operational playbooks to help remediate security threats.

Provides a local MCP interface to query captured, PII-scrubbed prompt telemetry from coding agents and browser chats, enabling time summaries, prompt search, and activity analysis without data leaving the machine.

Enables an AI assistant to list available monitors and take a single on-demand still screenshot of a selected monitor, with optional downscaling and JPEG or PNG output.

Enables structured learning with a verified loop: define goals as observable claims, learn through teach-lab-test-gate per claim, and get independently graded by an adversarial examiner to ensure genuine progress.

Enables vision-capable AI clients to read and adjust Capture One on macOS through local MCP stdio or JSON CLI, including curves, color tools, film grain, masks, reference matching, and real previews of rendered edits.

Enables vision-capable AI clients to read and adjust Capture One on Windows through an MCP stdio server (plus a JSON CLI), applying exposure, curves, color, layer and mask edits and returning real Capture One-rendered previews. It runs a local bridge to C1's native parameters with no presets, screenshots or synthetic input.

Skill librarian for coding agents: describe a task and get the few matching skills from a large local skill collection, then report whether they worked. Runs locally with Ollama and SQLite.

Enables an agent to submit a task brief and receive a short, validated list of skills from its full catalogue that are worth reading before starting.

Enables turning a video URL into a transcript and a concise idea summary using yt-dlp, Groq Whisper, and Gemini.

MCP server for controlling satellite ground station operations in the Trench simulation, including pass management, downlink control, and antenna pointing.

A local stdio MCP server that enables researchers to practice explaining their work outside a conference setting through a guided, one-question-at-a-time interview about their research, its audience, its consequences, and a concrete next step. It stores the saved answers in a local SQLite draft and returns an approximate rubric-based grade, without calling any model or requiring an API key.

Serves plain-text notes that an Obsidian user has explicitly published for AI over streamable HTTP, with full-text and embedding-based search. MCP clients can read and search those notes and queue suggested edits that the user's own client applies only if the AI rules allow it.

Enables CTF players to list challenges, retrieve challenge details, view the scoreboard, and submit flags.

Enables AI agents to directly manipulate Jupyter Notebook cells and structure through a secure, well-defined API, overcoming Cursor's AI agent mode limitations.

Enables AI assistants to interact with Databricks workspaces, running SQL queries, managing jobs, and exploring schemas via the Model Context Protocol.

Exposes a governed dbt MetricFlow semantic layer to AI agents through three tools — list metrics, list dimensions and query metrics — so questions about federal contract spend are answered from defined metrics rather than raw tables. Guardrails reject undefined metrics, raw columns, SQL in filters and bulk exports, and no tool can execute SQL.
