Cybersec toolkit: MCP server, setup and security
Cybersec toolkit is an open-source MCP server published on GitHub that lets an AI agent discover and run security tools through an authorization gated server. Its repository has 80 stars and its last commit is from October 23, 2026 and it is licensed under MIT.
What Cybersec toolkit does
According to its repository: “Install a large security toolset and discover and run it through an authorization-gated server for CTF, pentesting, bug bounty and DFIR.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Cybersec toolkit is listed under Security, a category of 133 servers in the directory, where it ranks #35 by stars.
Topics declared by the repository: blue-team, bug-bounty, claude-code, ctf-tools, cybersecurity, ethical-hacking.
Installing and connecting Cybersec toolkit
Distribution modes declared in the official MCP registry:
- Docker (OCI) image
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Python. Listed systems: Linux.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Cybersec toolkit. That does not replace reading the code.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on February 11, 2026, the 26zl/cybersec-toolkit repository has 80 stars and 16 forks, with 1 open issues. It has more stars than 62% of the servers in the directory. It received changes this month. Version published in the registry: 1.4.0 (October 15, 2026).
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
