# SSH-MCP Project Git Collaboration Setup
## Project Repository
**Repository Location:** proton.obr.sh (NOT photon)
- URL: https://git.proton.obr.sh
- Reason: photon.obnh.io will be used as a TEST TARGET for SSH-MCP server operations
## Git Configuration for This Project
### Gitea Instance: git.proton.obr.sh
- URL: https://git.proton.obr.sh
- Internal URL: http://localhost:3000 (from proton.obr.sh server)
- Username: olaf
- API-KEY: 151b26b25ffa4100ea776b09e2ed72a2dcb0787e
### Repository Name
**ssh-mcp-server** (suggested)
- Organization: OBNH or olaf
- Description: SSH-based MCP server for OBNH/OBR infrastructure management
## Collaboration Workflow
### For Claude Code
1. Create repository on proton.obr.sh via API or UI
2. Initialize git in /home/olaf/proton/ssh-mcp-project/
3. Commit implementation files
4. Push to proton.obr.sh
### For Agent Zero
1. Access repository via HTTP API: https://git.proton.obr.sh
2. Clone repository to accessible location (e.g., /tmp/ssh-mcp-project/repo/)
3. Make changes and commits
4. Push updates via API or git commands
## Why proton.obr.sh for This Project?
1. **Test Isolation**: photon.obnh.io is a primary target for SSH-MCP operations
- We'll use SSH-MCP to manage photon's Docker containers
- We'll test file operations on photon
- We'll verify infrastructure queries against photon
2. **Development Separation**: proton.obr.sh hosts the development repository
- Code is stored on proton
- Tests are executed against photon
- Clean separation of concerns
3. **Infrastructure Access**: SSH-MCP server can access BOTH
- Repository on proton.obr.sh (via ssh_get_file, ssh_exec)
- Test target photon.obnh.io (for validation)

- ✅ Proxmox host (10.50.0.72)
## Systemd Service
The SSH-MCP server runs as a systemd service:
```bash
# Service status
ssh root@10.50.0.110 systemctl status ssh-mcp-server
# Restart service
ssh root@10.50.0.110 systemctl restart ssh-mcp-server
# View logs
ssh root@10.50.0.110 journalctl -u ssh-mcp-server -f
```
**Service file**: `/etc/systemd/system/ssh-mcp-server.service`
## File Locations
**On LXC 110**:
- Server implementation: `/opt/ssh-mcp-server/server.py`
- HTTP wrapper: `/opt/ssh-mcp-server/http_wrapper.py`
- SSH config: `/root/.ssh/config`
- SSH private key: `/root/.ssh/id_ed25519`
- Service file: `/etc/systemd/system/ssh-mcp-server.service`
**On Agent Zero (LXC 105)**:
- Project documentation: `/tmp/ssh-mcp-project/README.md`
- Implementation: `/tmp/ssh-mcp-project/implementation/ssh_mcp_server.py`
## Integration with Claude Code
To use the SSH-MCP server with Claude Code, configure it via the Messages API:
```python
import anthropic
client = anthropic.Anthropic()
response = client.messages.create(
model="claude-sonnet-4-5-20250929",
max_tokens=1024,
mcp_servers=[
{
"type": "url",
"name": "ssh-infrastructure",
"url": "http://10.50.0.110:8081",
}
],
messages=[
{"role": "user", "content": "List all infrastructure hosts"}
]
)
```
## Integration with Agent Zero
Agent Zero can access the SSH-MCP server via:
1. **HTTP API**:
```bash
curl http://10.50.0.110:8081/tools/call \
-H "Content-Type: application/json" \
-d '{"name": "ssh_exec", "arguments": {"host": "proton", "command": "docker ps"}}'
```
2. **FastA2A API** (Agent Zero's API):
- Agent Zero can be instructed to use the HTTP API endpoints
- Shared filesystem: `/tmp/ssh-mcp-project/`
## Testing
All tools have been tested and verified working:
✅ ssh_list_hosts - Lists all hosts
✅ ssh_exec - Executes commands (tested: hostname on proton)
✅ ssh_docker_ps - Lists Docker containers (tested on proton)
✅ ssh_get_file - Reads remote files
✅ ssh_put_file - Writes remote files
✅ lxc_list - Lists LXC containers
✅ lxc_exec - Executes in LXC containers
## Security
- SSH key-based authentication (no passwords)
- Ed25519 keys (modern, secure)
- Unprivileged LXC container
- SSH StrictHostKeyChecking=no (for internal network only)
- Service runs as root (required for SSH access)
## Monitoring
```bash
# Check service status
ssh root@10.50.0.110 systemctl status ssh-mcp-server
# Check if port 8081 is listening
ssh root@10.50.0.110 "ss -tlnp | grep 8081"
# Test HTTP endpoint
curl http://10.50.0.110:8081/health
# View real-time logs
ssh root@10.50.0.110 journalctl -u ssh-mcp-server -f
```
## Troubleshooting
### Service not running
```bash
ssh root@10.50.0.110 systemctl restart ssh-mcp-server
ssh root@10.50.0.110 journalctl -u ssh-mcp-server -n 50
```
### SSH connectivity issues
```bash
# Test SSH from MCP server to target
ssh root@10.50.0.110 "ssh proton.obr.sh hostname"
# Check SSH key permissions
ssh root@10.50.0.110 "ls -la /root/.ssh/"
# Verify key is on target
ssh root@proton.obr.sh "grep ssh-mcp-server /root/.ssh/authorized_keys"
```
### HTTP endpoint not responding
```bash
# Check if uvicorn is running
ssh root@10.50.0.110 "ps aux | grep uvicorn"
# Check port binding
ssh root@10.50.0.110 "ss -tlnp | grep 8081"
# Check firewall
ssh root@10.50.0.110 "iptables -L -n | grep 8081"
```
## Next Steps
1. **Claude Code Integration**: Test MCP connector with Claude Code Messages API
2. **Agent Zero Integration**: Create custom tool or HTTP client in Agent Zero
3. **HTTPS/TLS**: Add TLS certificates for secure external access
4. **Authentication**: Implement OAuth 2.0 Bearer token authentication
5. **Monitoring**: Set up automated health checks and alerting
6. **Documentation**: Import this guide into Agent Zero's knowledge base
## Success Criteria
✅ LXC container 110 created and operational
✅ SSH keys configured on all infrastructure hosts
✅ MCP server implementation complete
✅ HTTP/SSE transport wrapper functional
✅ All 7 MCP tools tested and working
