OpenCode marks an MCP server failed when it does not come up at startup or when a live connection drops, and never retries. A new managed plugin reconnects those servers with a per-server backoff (1s doubling to a 30s cap), wakes early on mcp.tools.changed, and stops on dispose. Only the failed state is retried; disabled and auth states stay untouched. The OPENCODE_CONFIG_CONTENT merge that agent-tool and system-prompt each carried is now one shared helper so the three managed plugins compose.
