opencode v1.17.8 delivers multiple MCP reliability fixes, a Cloudflare AI Gateway API key correction, faster session timeline loading, and desktop UI improvements.
Score breakdown
This release resolves several MCP integration failures — including schema validation errors and timeout drops on long-running tools — that previously blocked OpenAI-compatible and Cloudflare AI Gateway users from reliably running MCP-powered workflows.

opencode v1.17.8, released by the `opencode-agent[bot]`, addresses a cluster of MCP-related bugs alongside performance and desktop improvements. On the MCP front, OpenAI-compatible providers now accept tool schemas that previously failed validation (fixed by @jquense), and MCP tools that lack declared schema properties now work correctly with providers that require object properties. Long-running MCP tools no longer time out prematurely when they report progress — their timeout is now kept alive during progress events (fixed by @Nomadcxx). The MCP OAuth callback server has also been tightened: it now shuts down once authorization finishes or is cancelled, error pages correctly escape provider error text, and tool failures now surface the server's actual error text rather than a generic failure message.
On the infrastructure side, the Cloudflare AI Gateway fix (by @keefetang) ensures the configured API key is passed correctly via `createUnified`.
On the infrastructure side, the Cloudflare AI Gateway fix (by @keefetang) ensures the configured API key is passed correctly via `createUnified`. The core UI improvement makes session timelines load much faster while eliminating flicker and scroll jumps. Desktop users gain a Home tab toggle for quick navigation between Home and the last active tab, and the file and folder picker in the v2 layout is described as faster and easier to navigate.
