A minimal, intentionally vulnerable MCP server to demonstrate SAFE‑T1001 (Tool Poisoning Attack). Use it during the hackathon to: identify the vulnerability, map it to SAFE‑T1001, and propose mitigations.

• Prereqs: Docker installed; internet allowed for image pull.
• Pull (GHCR example): docker pull ghcr.io/bishnubista/safe-mcp-sandbox:v0.1.0
• Run (unsafe mode, default):
  • macOS/Linux: docker run --rm -i --read-only --pids-limit 128 --memory 256m --security-opt no-new-privileges --network none -v "$(pwd)/flags:/opt/flags:ro" ghcr.io/bishnubista/safe-mcp-sandbox:v0.1.0
  • Windows PowerShell: docker run --rm -i --read-only --pids-limit 128 --memory 256m --security-opt no-new-privileges --network none -v "${PWD}/flags:/opt/flags:ro" ghcr.io/bishnubista/safe-mcp-sandbox:v0.1.0
• Run (safe mode demo):
  • Add -e MODE=safe before the image name, or use ./scripts/run-safe.sh / scripts\run-safe.cmd.
  • Tip: Override scripts with a pinned tag: IMAGE=ghcr.io/bishnubista/safe-mcp-sandbox:v0.1.0 ./scripts/run-unsafe.sh
• Connect with an MCP client (Claude Desktop recommended). See docs/CLIENTS.md.

• Recon tool metadata, trigger the poisoned behavior, capture evidence of model coercion/exfiltration, map to SAFE‑T1001, and propose a mitigation. See docs/HACKATHON.md for the exact tasks and scoring.

• server/: Node.js (TypeScript) MCP server (unsafe/safe modes)
• docker/: Dockerfile
• flags/: Sample flag.txt mounted read‑only at runtime
• docs/: Event docs and materials (HACKATHON.md, CLIENTS.md, MITIGATIONS.md, SCORING.md, ROADMAP.md)
• scripts/: Convenience run scripts for macOS/Linux and Windows

• Container runs without network, read‑only, as non‑root in final image.
• Bind‑mount only flags/ read‑only; do not mount sensitive host paths.
• Issues and improvements welcome via PRs (see docs/ROADMAP.md).

• CI builds and pushes images to GHCR on tags (v*) and on main (edge).
• Image: ghcr.io/bishnubista/safe-mcp-sandbox with tags like v0.1.0, v0.1, v0, latest, and edge.
• Tag and push to release:
  • git tag v0.1.0 && git push origin v0.1.0
  • See docs/ROADMAP.md for future tagging by scenario.
