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
