|
|
|
|
## Overview
|
|
|
|
A production-ready Model Context Protocol (MCP) server that provides comprehensive access to Linux `/proc` filesystem and system management capabilities. Supports both JSON-RPC over stdio and HTTP with Server-Sent Events (SSE).
|
|
|
|
## Features Implemented
|
|
|
|

|
|
- Network interface statistics (`/proc/net/dev`)
|
|
- Disk I/O statistics (`/proc/diskstats`)
|
|
- Process information (`/proc/[pid]/`)
|
|
- Raw file reading from any `/proc` path

## Security Considerations
|
|
|
|
⚠️ **Important**:
|
|
- Provides direct system access
|
|
- Write operations require appropriate permissions
|
|
- Should implement authentication for production
|
|
- Consider read-only mode for untrusted clients
|
|
- Monitor and log all operations
|
|
|
|
## Testing
|
|
|
|
```bash
|
|
npm test # Run tests
|
|
npm run test:watch # Watch mode
|
|
npm run test:coverage # Coverage report
|
|
```
|
|
|
|
Current: 10 passing tests covering core functionality
