# opencode 1.17.10: MCP resource tools, V2 plugin API, `--mini` CLI mode

> Adds MCP resource template listing and resource-read tools, a V2 plugin API with namespaced hooks, and a `--mini` CLI mode. Plugin authors and MCP integrators are the main audience; legacy MCP tool names were restored, so existing integrations keep working.

## What changed


**Core**
- MCP resource template listing and MCP resource read tools; templates hidden when access is denied; name collisions across servers with identical keys prevented
- MCP server instructions appended to session context
- opencode-managed provider integration support
- New `--mini` CLI mode
- Legacy MCP tool names restored for existing integrations; v1 account config loading restored
- MCP OAuth callbacks bound to IPv4 loopback
- Skill base directories emitted as filesystem paths instead of `file://` URLs
- `gpt-5.5-pro` hidden when authenticated via Codex OAuth
- Snapshots from subdirectories now include only the correct files and paths; ACP resource text fixed on Windows and other cross-platform path cases

**Extensions**
- V2 plugin API for Effect and Promise plugins; namespaced plugin hook APIs

**TUI**
- Configurable keybind to open the diff viewer; diff viewer can compare against the main branch
- Worker rejections no longer break the TUI process

**Desktop**
- Per-tab draft prompt state, session progress indicator, mobile bottom navigation, collapsible server sections, server-aware session routes

**SDK**
- Provider integration IDs exposed
