Claude Code 2.1.85 download

- Added CLAUDE_CODE_MCP_SERVER_NAME and CLAUDE_CODE_MCP_SERVER_URL environment variables to MCP headersHelper scripts, allowing one helper to serve multiple servers
- Added conditional if field for hooks using permission rule syntax (e.g., Bash(git *)) to filter when they run, reducing process spawning overhead
- Added timestamp markers in transcripts when scheduled tasks (/loop, CronCreate) fire
- Added trailing space after [Image #N] placeholder when pasting images
- Deep link queries (claude-cli://open?q=…) now support up to 5,000 characters, with a "scroll to review" warning for long pre-filled prompts
- MCP OAuth now follows RFC 9728 Protected Resource Metadata discovery to find the authorization server
- Plugins blocked by organization policy (managed-settings.json) can no longer be installed or enabled, and are hidden from marketplace views
- PreToolUse hooks can now satisfy AskUserQuestion by returning updatedInput alongside permissionDecision: "allow", enabling headless integrations that collect answers via their own UI
- tool_parameters in OpenTelemetry tool_result events are now gated behind OTEL_LOG_TOOL_DETAILS=1
- Fixed /compact failing with "context exceeded" when the conversation has grown too large for the compact request itself to fit
- Fixed /plugin enable and /plugin disable failing when a plugin's install location differs from where it's declared in settings
- Fixed --worktree exiting with an error in non-git repositories before the WorktreeCreate hook could run
- Fixed deniedMcpServers setting not blocking claude.ai MCP servers
- Fixed switch_display in the computer-use tool returning "not available in this session" on multi-monitor setups
- Fixed crash when OTEL_LOGS_EXPORTER, OTEL_METRICS_EXPORTER, or OTEL_TRACES_EXPORTER is set to none
- Fixed diff syntax highlighting not working in non-native builds
- Fixed MCP step-up authorization failing when a refresh token exists — servers requesting elevated scopes via 403 insufficient_scope now correctly trigger the re-authorization flow
- Fixed memory leak in remote sessions when a streaming response is interrupted
- Fixed persistent ECONNRESET errors during edge connection churn by using a fresh TCP connection on retry
- Fixed prompts getting stuck in the queue after running certain slash commands, with up-arrow unable to retrieve them
- Fixed Python Agent SDK: type:'sdk' MCP servers passed via --mcp-config are no longer dropped during startup
- Fixed raw key sequences appearing in the prompt when running over SSH or in the VS Code integrated terminal
- Fixed Remote Control session status staying stuck on "Requires Action" after a permission is resolved
- Fixed shift+enter and meta+enter being intercepted by typeahead suggestions instead of inserting newlines
- Fixed stale content bleeding through when scrolling up during streaming
- Fixed terminal left in enhanced keyboard mode after exit in Ghostty, Kitty, WezTerm, and other terminals supporting the Kitty keyboard protocol — Ctrl+C and Ctrl+D now work correctly after quitting
- Improved @-mention file autocomplete performance on large repositories
- Improved PowerShell dangerous command detection
- Improved scroll performance with large transcripts by replacing WASM yoga-layout with a pure TypeScript implementation
- Reduced UI stutter when compaction triggers on large sessions
