OpenCode v1.17.7: MCP Servers Now Receive Workspace Root Context
SST
SST shipped OpenCode v1.17.7 on June 14. The headline change: MCP servers now receive the current workspace as a client root context, allowing servers to make project-aware decisions without manual path configuration. Also in v1.17.7: plugin clients reuse active servers rather than assuming the default local port; ACP shell tool calls now surface the command and working directory from the start of output; new-session routes stay scoped to their own draft server. Earlier this week, v1.17.0 (June 10) was the major release adding WSL-backed Desktop support, fff-based file search for faster monorepo navigation, and Cohere North model support.
Why it matters
The MCP workspace root context change is the most developer-impactful: MCP server authors can now write context-aware tools that automatically adapt to the project in focus, eliminating per-project configuration boilerplate. OpenCode serves as the primary open-source alternative to Cursor and Claude Code, connecting to 75+ AI providers.
Importance: 2/5
MCP workspace root context is a meaningful DX improvement for MCP server authors; steady release cadence in open-source coding agent space.
