This plugin automatically starts the agentmemory backend (REST API + iii-engine) when OpenCode loads its configuration. It runs once per OpenCode process and health-checks the backend every 60 seconds, restarting it if the process dies.
Add to your OpenCode config:
OpenCode will automatically install the package at startup. See the OpenCode Plugins documentation for more details.
Place the plugin file in .opencode/plugins/:
.opencode/plugins/
└── agentmemory-launcher.ts
Files in this directory are automatically loaded at startup.
- Download
agentmemory-launcher.tsfrom the latest GitHub Release - Place it in
.opencode/plugins/:
.opencode/plugins/
└── agentmemory-launcher.ts
OpenCode loads .ts files from .opencode/plugins/ automatically at startup.
This launcher starts the agentmemory backend. To use agentmemory with OpenCode, also install the agentmemory plugin and refer to the OpenCode agentmemory plugin usage guide for setup instructions, available tools, and configuration options.
To update agentmemory to the latest version:
npx @agentmemory/agentmemory upgradeAfter updating, stop the running agentmemory process and clear the npx cache:
Windows (PowerShell):
# Stop the agentmemory process
Get-Process -Name "node" | Where-Object {
(Get-CimInstance Win32_Process -Filter "ProcessId = $($_.Id)").CommandLine -match 'agentmemory'
} | Stop-Process -Force
# Clear the npx cache
Get-ChildItem "$env:LOCALAPPDATA\npm-cache\_npx" -Directory | Where-Object {
Test-Path "$($_.FullName)\node_modules\@agentmemory"
} | Remove-Item -Recurse -ForceRestart OpenCode to relaunch agentmemory with the updated version.
- On first config load: The plugin starts a health-check interval (60s)
- Health check: Pings
GET /agentmemory/livezon the backend (public, no auth) - Auto-restart: If the health check fails, spawns
npx @agentmemory/agentmemoryin a detached process - Debug mode: Set
