# Task #92: Trinity Core — Desktop MCP Gateway
|
||||
|
||||
## Overview
|
||||
|
||||
A dedicated Ubuntu Server on Michael's HP laptop that acts as an MCP gateway, allowing Claude.ai to execute commands on Firefrost servers with approval workflows.
|
||||
|
||||
**Hardware:** HP Laptop (dedicated, shelf-mode)
|
||||
**OS:** Ubuntu Server 24.04 LTS
|
||||
**Codename:** Trinity Core
|
||||
|
||||
## The Vision
|
||||
|
||||
```
|
||||
Claude.ai → MCP Request → Laptop (Trinity Core) → SSH → Firefrost Servers
|
||||
↓
|
||||
Arbiter (Discord Approval)
|
||||
↓
|
||||
Michael clicks "Approve"
|
||||
↓
|
||||
Command executes
|
||||
```
|
||||
|
||||
No more copy-paste from Claude to MobaXterm. Claude can execute commands directly with Michael's approval.
|
||||
|
||||
## Architecture (Gemini-Approved)
|
||||
|
||||
| Component | Decision | Rationale |
|
||||
|-----------|----------|-----------|
|
||||
| MCP Server | Docker container | Isolation — bugs stay contained |
|
||||
| SSH Keys | One Ed25519 key | `claude_executor` user on all target servers |
|
||||
| Firewall | UFW | Allow 22, 9090 only; deny all else |
|
||||
| Security | fail2ban + Cloudflare Access | Defense in depth |
|
||||
| Approval | Arbiter integration | Don't reinvent — use existing Discord bot |
|
||||
| Tunnel | cloudflared | Zero incoming ports needed |
|
||||
| Startup | docker-compose + systemd | Auto-recovery on reboot |
|
||||
| Monitoring | Uptime Kuma | CPU temp, disk I/O, endpoint health |
|
||||
|
||||
## Implementation Phases
|
||||
|
||||
### Phase 1: Ubuntu Server Setup ⬅️ CURRENT
|
||||
|
||||

8. [ ] Mount SSH keys as read-only volume
|
||||
|
||||
### Phase 5: Arbiter Integration
|
||||
|
||||
1. [ ] Add MCP approval endpoint to Arbiter
|
||||
2. [ ] Create `#mcp-approvals` Discord channel
|
||||
3. [ ] Implement approval button UI
|
||||
4. [ ] Add timeout handling (auto-deny after X minutes)
|
||||
5. [ ] Implement callback to MCP server

6. [ ] Add audit logging
|
||||
|
||||
### Phase 6: Testing & Monitoring

||||
## Target Servers
|
||||
|
||||
| Server | IP | claude_executor needed |
|
||||
|--------|-----|------------------------|
|
||||
| Command Center | 63.143.34.217 | Yes |
|
||||
| TX1 Dallas | 38.68.14.26 | Yes |
|
||||
| NC1 Charlotte | 216.239.104.130 | Yes |
|
||||
| Panel VPS | 45.94.168.138 | Maybe |
|
||||
| Dev Panel | 64.50.188.128 | Maybe |
|
||||
|
||||
## Security Model
|
||||
|
||||
**Zero-Trust Principles:**
|
||||
- Cloudflare Access validates identity before traffic reaches laptop
|
||||
- MCP server validates request format/signature
|
||||
- Arbiter requires Discord button approval for execution
|
||||
- `claude_executor` has restricted sudo (no root)
|
||||
- SSH keys mounted read-only in container
|
||||
- All commands logged for audit
|
||||
|
||||
**Command Classification:**
|
||||
- **Safe:** Read-only commands (ls, cat, systemctl status) — maybe auto-approve
|
||||
- **Moderate:** Service restarts, git operations — require approval
|
||||
- **Dangerous:** File deletion, user management — require approval + confirmation
|
||||
|
||||
## Related Tasks
|
||||
|
||||
- **Task #93:** Trinity Codex (RAG knowledge base) — could query via MCP
|
||||
- **Task #94:** Global Restart Scheduler — could trigger via MCP
|
||||
- **Task #87:** Arbiter lifecycle handlers — approval system extends this
|
||||
|
||||
## Consultations
|
||||
|
||||
- `docs/consultations/gemini-claude-code-workflow-2026-04-08.md` — Original architecture
|
||||
- `docs/consultations/gemini-task-92-ubuntu-setup-2026-04-09.md` — Implementation guidance
|
||||
|
||||
## Success Criteria
|
||||
|
||||
- [ ] Laptop runs Ubuntu Server, accessible via Cockpit
|
||||
- [ ] Claude.ai can send MCP requests through Cloudflare Tunnel
|
||||
- [ ] Approval buttons appear in Discord
|
||||
- [ ] Commands execute on target servers after approval
|
||||
- [ ] Full audit trail exists
|
||||
- [ ] System auto-recovers from reboots

|
||||
|
||||
## Step 3: First Boot — System Update
|
||||
|
||||
SSH in from your main PC, or use the laptop directly:
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
```
|
||||
|
||||
```bash
|

|
||||
## Step 4: Install Cockpit (Web Management)
|
||||
|
||||
```bash
|
||||
sudo apt install cockpit -y
|
||||
```
|
||||
|
||||
```bash
|

## Step 5: Configure UFW Firewall
|
||||
|
||||
```bash
|
||||
sudo apt install ufw -y
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo ufw default deny incoming
|

|
||||
|
||||
## Step 6: Install fail2ban
|
||||
|
||||
```bash
|
||||
sudo apt install fail2ban -y
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo systemctl enable fail2ban
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo systemctl start fail2ban
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo fail2ban-client status
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 7: Configure Lid Switch (Shelf Mode)
|
||||
|
||||
Edit the config:
|
||||
|
||||
```bash
|
||||
sudo nano /etc/systemd/logind.conf
|
||||
```
|
||||
|
||||
Find and uncomment/change this line:
|
||||
```
|
||||
HandleLidSwitch=ignore
|
||||
```
|
||||
|
||||
Save (Ctrl+O, Enter, Ctrl+X), then:
|
||||
|
||||
```bash
|
||||
sudo systemctl restart systemd-logind
|
||||
```
|
||||
|
||||
**Test:** Close the lid — laptop should stay on.
|
||||
|
||||
---
|
||||
|
||||
## Step 8: Install Docker
|
||||
|
||||
```bash
|
||||
sudo apt install ca-certificates curl -y
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo install -m 0755 -d /etc/apt/keyrings
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo chmod a+r /etc/apt/keyrings/docker.asc
|
||||
```
|
||||
|
||||
```bash
|
||||
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y
|
||||
```
|
||||
|
||||
Add yourself to docker group (no sudo needed for docker commands):
|
||||
|
||||
```bash
|
||||
sudo usermod -aG docker michael
|
||||
```
|
||||
|
||||
**Log out and back in**, then test:
|
||||
|
||||
```bash
|
||||
docker run hello-world
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 9: Install Node.js (for MCP development)
|
||||
|
||||
```bash
|
||||
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo apt install nodejs -y
|
||||
```
|
||||
|
||||
```bash
|
||||
node --version
|
||||
```
|
||||
|
||||
```bash
|
||||
npm --version
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 10: Verify Installation
|
||||
|
||||
Run these checks:
|
||||
|
||||
```bash
|
||||
echo "=== System ===" && uname -a
|
||||
```
|
||||
|
||||
```bash
|
||||
echo "=== Cockpit ===" && systemctl status cockpit.socket --no-pager
|
||||
```
|
||||
|
||||
```bash
|
||||
echo "=== UFW ===" && sudo ufw status
|
||||
```
|
||||
|
||||
```bash
|
||||
echo "=== fail2ban ===" && sudo fail2ban-client status
|
||||
```
|
||||
|
||||
```bash
|
||||
echo "=== Docker ===" && docker --version
|
||||
```
|
||||
|
||||
```bash
|
||||
echo "=== Node ===" && node --version
|
||||
```
