# Security
|
|
|
|
## Threat Model
|
|
|
|
### Overview
|
|
|
|
OpenCode is an AI-powered coding assistant that runs locally on your machine. It provides an agent system with access to powerful tools including shell execution, file operations, and web access.
|
|
|
|
### No Sandbox
|
|
|
|
OpenCode does **not** sandbox the agent. The permission system exists as a UX feature to help users stay aware of what actions the agent is taking - it prompts for confirmation before executing commands, writing files, etc. However, it is not designed to provide security isolation.
|
|
|
|
If you need true isolation, run OpenCode inside a Docker container or VM.
|
|
|
|
### Server Mode
|
|
|
|
Server mode is opt-in only. When enabled, set `OPENCODE_SERVER_PASSWORD` to require HTTP Basic Auth. Without this, the server runs unauthenticated (with a warning). It is the end user's responsibility to secure the server - any functionality it provides is not a vulnerability.
|
|
|
|
### Out of Scope
|
|
|
|
| Category | Rationale |
|
|
| ------------------------------- | ----------------------------------------------------------------------- |
|
|
| **Server access when opted-in** | If you enable server mode, API access is expected behavior |
|
|
| **Sandbox escapes** | The permission system is not a sandbox (see above) |
|
|
| **LLM provider data handling** | Data sent to your configured LLM provider is governed by their policies |
|
|
| **MCP server behavior** | External MCP servers you configure are outside our trust boundary |
|
|
| **Malicious config files** | Users control their own config; modifying it is not an attack vector |
