Swarm Code 1.8.13

Swarm Code 1.8.13 resolves GitLab MCP OAuth rejection loops and group permission setup guidance, implements MCP protocol version negotiation (2025-11-25) for GitLab, expands OAuth discovery to POST-only servers like Tavily and Resend, and upgrades Exa Search to direct HTTP transport. Apple silicon, macOS 26 or later.

Bug fixes

• GitLab OAuth 403 & Sign-in Loop: Resolved a bug where GitLab's "MCP server not enabled for any of your groups" 403 response was treated as unauthorized OAuth, purging valid credentials and causing a continuous "Sign-in was rejected" loop. Swarm Code now preserves the OAuth token, marks the connection as requiring setup, and provides direct instructions to enable group-level MCP access.
• Safe OAuth Credential Retention: Updated MCPStore so only genuine HTTP 401 Unauthorized responses trigger credential sign-out, preventing permission or policy denials (403) from wiping stored Keychain credentials.
• Exa Search MCP Transport: Reconfigured Exa MCP from unsupported OAuth to direct HTTP transport (https://mcp.exa.ai/mcp) with optional API key support, enabling instant, error-free web search capabilities.
• OAuth Discovery POST Fallback: Added automatic HTTP POST fallback in MCPOAuth.protectedResourceMetadataURL when endpoints return HTTP 405 to GET requests, enabling seamless OAuth discovery for servers such as Tavily and Resend.

Refinements

• Protocol Version Negotiation: Added dynamic protocol version selection in MCPWire and MCPProbe, negotiating 2025-11-25 for GitLab while preserving 2024-11-05 across other catalog servers to avoid version mismatch errors.
• GitLab Setup Guidance: Clarified instructions in MCPSetupGuide guiding users directly to Group Settings › General › Permissions and group features › Model Context Protocol (MCP).

Swarm Code 1.8.12

Swarm Code 1.8.12 fixes critical MCP proxy routing and subpath forwarding, chunked HTTP request handling, empty header placeholder dropping, Figma personal access token authentication, asynchronous login shell environment loading, and robust multi-tier Codex MCP recovery. Apple silicon, macOS 26 or later.

Bug fixes

• MCP Proxy Subpath & Query Routing: Fixed a 502 Bad Gateway error caused by strict path matching in MCPProxy. The proxy now accurately forwards arbitrary subpaths and query strings (e.g. /messages, /sse?session_id=...) to upstream servers.
• Chunked Request Decoding: Added progressive HTTP/1.1 chunked transfer-encoding decoding to MCPProxy, eliminating 411 Length Required errors with streaming client libraries.
• Empty Header & Token Sanitization: Sanitized resolved headers in MCPCatalogEntry+Resolve to cleanly drop unset optional placeholders (such as {key} in Context7) and empty Bearer headers rather than sending malformed credentials.
• Figma Token Authentication: Replaced unsupported dynamic OAuth registration on Figma with direct personal access token support (X-Figma-Token and Authorization), matching official Figma API standards.
• Codex Session Resilience: Updated CodexSession and MCPProviderConfig to validate server transports before writing and gracefully fallback to local stdio servers if a remote MCP endpoint is temporarily unreachable.
• Asynchronous Environment Initialization: Ensured LoginEnvironment.load() is fully awaited prior to binary resolution in MCPProbe and MCPHub, preventing false "command missing" errors for npx, uvx, and custom tools on startup.

Refinements

• Protocol Standardization: Aligned default protocol version to official Model Context Protocol release (2024-11-05) across MCPWire and JavaScript bridge source.
• OAuth Discovery Compatibility: Expanded MCPOAuth protected resource metadata detection to accept HTTP 403 and 405 responses containing WWW-Authenticate challenge headers.
• Extended Shell Environment Timeout: Increased login environment read timeout from 8s to 15s to accommodate comprehensive user shells with heavy zsh/nvm/conda configurations.

Swarm Code 1.8.11

Swarm Code 1.8.11 fixes a critical crash when connecting to MCP servers, shifts credential resolution off the Main Thread with safety timeouts, and adds thread-safe token caching. Apple silicon, macOS 26 or later.

Bug fixes

• Fixed MCP Connection Crash: Resolved a fatal AttributeGraph re-entrancy crash (AG::precondition_failure) triggered by synchronous runloop pumping when connecting to MCP servers like GitHub.
• Non-Blocking Credential Resolution: Shifted external CLI subprocess execution (gh auth token / git credential fill) to background queues with a 3-second safety timeout, preventing Main Thread deadlocks and UI freezes.
• MCP Panel Sizing: Streamlined NSHostingController presentation in floating MCP key and setup panels, eliminating redundant view hierarchy allocations during presentation.

Refinements

• Thread-Safe Credential Caching: Added in-memory token caching with instant TTL lookup and startup cache warming in MCPStore, eliminating repetitive CLI process spawning during view updates.

Swarm Code 1.8.10

Swarm Code 1.8.10 resolves critical Model Context Protocol (MCP) connectivity issues across remote and local servers, brings full Server-Sent Events (SSE) streaming support, stabilizes macOS Keychain secret handling, and adds automatic GitHub CLI authentication integration. Apple silicon, macOS 26 or later.

Bug fixes

• Remote MCP Server Streaming: Implemented real-time Server-Sent Events (SSE / text/event-stream) streaming in MCPWire, resolving hangs and HTTP 400/404 timeouts when connecting to GitHub Copilot MCP and remote endpoints.
• MCP Keychain Access: Modernized secret credential storage with unified APIKeychain, eliminating authorization lock failures that caused stored tokens to return empty and break server connections.
• Stdio Process Lifecycle: Fixed child process identification and cleanup in StdioProcess and MCPHub, preventing local stdio MCP servers from deadlocking or becoming unresponsive.

Refinements

• Automatic GitHub Authentication: Integrated system-level GitHub CLI (gh auth token) and environment credential resolution so GitHub MCP can connect with zero manual token configuration.

Swarm Code 1.8.9

Swarm Code 1.8.9 cleans up installer window branding by regenerating the official macOS DMG installer background with authentic Swarm Code typography, purging legacy Droppy Code artwork, and integrating cross-platform desktop monorepo updates. Apple silicon, macOS 26 or later.

Bug fixes

• Installer Window Branding: Regenerated the multi-resolution DMG installer background (installer-background.tiff), replacing residual "Droppy Code" title artwork with authentic bold "Swarm Code" wordmark and layout.
• Packaging Assets: Sanitized desktop packaging assets with the official Swarm Code wordmark.

Refinements

• Markdown Link Navigation: Added MarkdownLinkOpener support to directly jump to local workspace files and line numbers in your default editor.

Bug fixes

• Timeline Window Freeze: Replaced lazy vertical scrolling with bounded eager timeline rendering, eliminating macOS window edge hangs and layout loops.
• Non-Blocking Hydra Merges: Transitioned Hydra landing pipeline to a non-blocking queued merge flow with automated retry on forge branch conflicts.
• Disk Cache Thrashing: Set shared URLCache disk capacity to zero and debounced library persistence to eliminate disk write thrashing during extended coding sessions.

Swarm Code 1.8.7

Swarm Code 1.8.7 eliminates macOS Keychain modal password prompts across all background operations, enforcing non-interactive Security framework queries for GitHub update tokens and Claude CLI credential discovery. Apple silicon, macOS 26 or later.

Bug fixes

• Keychain Password Prompts: Enforced strict non-interactive authentication (kSecUseAuthenticationUIFail) on GitHub update checker token queries, eliminating macOS login keychain modal password dialogs on app launch.
• Direct Credential Discovery: Replaced external /usr/bin/security subprocess invocations in PlanLimits with in-process Security.framework queries, preventing external process security prompts and respecting app-wide non-interactive keychain access policies.

Swarm Code 1.8.6

Swarm Code 1.8.6 delivers reliable desktop notifications with the official app logo attached, adds system notification permission status detection with direct links to macOS Settings, and enhances dock bounce attention for minimized states. Apple silicon, macOS 26 or later.
