OpenCode June 24 Release Adds MCP Server Instructions to Session Context, Resource Tools, and a '--mini' CLI Mode

OpenCode (GitHub Releases)·low signal

The open-source OpenCode agent shipped a June 24 release that injects MCP server instructions into session context, adds OpenCode-managed provider integration, MCP resource-template listing and resource-read tools, and a lightweight --mini CLI mode. The MCP-centric changes reflect the broader push (alongside the stabilizing 2026 MCP spec) toward agents that natively consume server-provided instructions and resources. It's a small but concrete signal that open coding agents are standardizing on richer MCP context handling rather than bespoke tool wiring.
