Tools
| Tool | Description | |------|-------------| | list_memory_usage | System memory summary (like free -h) | | list_top_processes | Top N memory consumers with details | | find_stale_processes | Find sleeping/idle processes by age, state, name pattern | | kill_processes | Kill PIDs with safety checks |
Installation
Claude Code
Add to ~/.config/claude-code/mcp.json:
{
"mcpServers": {
"mcp-memory": {
"command": "nix",
"args": ["run", "github:paolino/mcp-memory-server", "--refresh"]
}
}
}The --refresh flag ensures you always get the latest version. Remove it to use the cached version for faster startup.
From source
git clone https://github.com/paolino/mcp-memory-server
cd mcp-memory-server
nix develop
just install
just runUsage Examples
Show memory usage
Ask Claude: "Show me current memory usage"
Find stale GHC processes
Ask Claude: "Find old GHC or cabal processes using more than 100MB"
This calls find_stale_processes with:
name_pattern:"ghc|cabal"min_memory_mb:100
Kill processes
Ask Claude: "Kill these PIDs: 1234, 5678"
Safety checks:
- Refuses PID 0/1
- Refuses root-owned processes (unless running as root)
- Optional name confirmation to prevent killing wrong process
- Default SIGTERM, SIGKILL only when explicit
