MCP Memory Server

MCP server for memory management with process inspection and cleanup tools.

Documentation

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 run

Usage 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

Development

nix develop
just test       # Run tests
just run        # Start server
just format     # Format code
just lint       # Lint code
