Cybersecurity training, simulation, and incident response MCP server
Connect Cybersim to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Cybersecurity training, simulation, and incident response MCP server. The cybersim mcp server is what makes that connection.
CyberSim Pro is a professional-grade Model Context Protocol (MCP) server purpose-built for cybersecurity training, purple-team collaboration, and executive readiness. It equips AI assistants and automation pipelines with structured tools to generate scenarios, simulate adversaries, analyse telemetry, investigate incidents, perform forensics, and publish board-ready reports—all while recording an immutable audit trail.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
CYBERSIM_API_KEY — require Authorization: Bearer headerCYBERSIM_IP_ALLOW — comma-separated list (127.0.0.1,::1,local,203.0.113.10)CYBERSIM_APPROVAL_TOKEN — shared secret required for restricted tools (simulate_attack, stop_simulation, replay_telemetry)CYBERSIM_RBAC_CONFIG — optional path to a JSON role policy (see Role-Based Access & Approvals)Configuration is passed through the environment: CYBERSIM_API_KEY, CYBERSIM_APPROVAL_TOKEN, CYBERSIM_AUDIT_HMAC_KEY, CYBERSIM_AUDIT_CHAIN_ID, CYBERSIM_AUDIT_SEAL_KEY, CYBERSIM_SCIM_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Cybersim's toolset — CYBERSIM_API_KEY, CYBERSIM_IP_ALLOW, CYBERSIM_APPROVAL_TOKEN and 1 more — is a fair guide to whether it matches your workflow. It is maintained by kayembahamid; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
