# opencode 1.17.8: MCP schema, OAuth and timeout fixes

> Bugfix release concentrated on MCP. Tool schemas that previously failed validation on OpenAI-compatible providers now pass, long-running MCP tools keep their timeout alive while reporting progress, and the OAuth callback server shuts down after authorization. Also faster session timeline loading.

## What changed


- MCP: OpenAI-compatible providers accept tool schemas that previously failed validation
- MCP: tools without declared schema properties work with providers expecting object properties
- MCP: long-running tools keep their timeout alive when reporting progress

- MCP: tool failures surface the server's error text instead of a generic failure
- Provider: Cloudflare AI Gateway now receives the configured API key
- Core: session timelines load faster, without flicker or scroll jumps
- Desktop: Home tab toggle to switch between Home and last tab; faster file/folder picker in the v2 layout
