Claude Makes Enterprise-Managed Auth for MCP Connectors Generally Available
Anthropic says enterprise-managed auth for MCP connectors is now generally available. Claude Team and Enterprise admins can centralize authorization through their identity provider, while users receive connector access automatically without individual OAuth consent flows.
Claude Code Remote Control Can Start Sessions From Your Phone
Claude Code's Remote Control update lets you start a session from the Claude mobile app, choose a directory on a connected machine, and continue working from a phone, tablet, or browser. The code and tools still run on the local machine, while the phone acts as a remote control surface.
Claude Security Brings Mythos 5 Scans to Enterprise Customers
Anthropic says Claude Security scans now run on Claude Mythos 5 for Claude Enterprise customers. The public-beta product scans connected codebases, returns CWE, confidence, severity, and suggested-fix details, and opens approved fixes in Claude Code on the web without exposing the Mythos model directly.
Claude Platform Makes Computer Use, Browser Use, Skills, and Files Generally Available
Anthropic says computer use, browser use, the Skills API, and the Files API are now generally available on the Claude Platform, combining multi-action software control with versioned skills and reusable files for production agents.
Claude Managed Agents Add Memory Stores, Domain Controls, and a Redesigned Console
Anthropic's Claude Managed Agents updates let self-hosted sandbox sessions attach memory stores, restrict web_search and web_fetch with allowed_domains or blocked_domains, and inspect multi-agent sessions in a redesigned Claude Console viewer.
Claude Can Now Send Gmail Emails and Manage Google Drive Files
Anthropic's Claude can now send and reply to Gmail messages and manage Google Drive files from the connectors menu. The official announcement says the update is available on paid plans, while Anthropic's current help documentation details approval prompts, supported actions, admin controls, and important data-access limits.
Claude Code Desktop Adds Auto-Continue After Usage Limits
Claude Code now continues your session automatically when a claude.ai usage limit resets. Anthropic's changelog documents the behavior in version 2.1.234 as on by default, with an opt-out in /config named 'Continue automatically at usage limit'. It resumes work after a reset; it does not raise or remove the limit.
Claude in Chrome Sessions Now Continue Across Devices
Anthropic says Claude in Chrome sessions now carry over to desktop, web, and mobile. Conversations are saved to the user's account, while skills and connectors can work from the browser; Claude's current Chrome page lists the extension as available on all paid plans.
Prompting Claude Fable 5: What to Change and What to Delete
Prompt Claude Fable 5 with less, not more: brief instructions now beat enumerated rule lists, and old skills written for prior models can degrade output. Use effort as your main cost control, expect longer turns, ground progress claims in tool results, and configure fallback to Opus 4.8 for safeguard refusals.
Prompting Claude Opus 5: Trim the Verbosity, Delete the Verification
Claude Opus 5 needs opposite prompting from its predecessors: you prompt for conciseness because effort no longer controls visible length, and you delete verification and double-check instructions because the model already does both. Constrain scope on narrow tasks, cap subagent spawning for cost, and keep thinking enabled at low effort rather than disabling it.
Claude Code Will Make Auto Mode the Default on August 14
Anthropic says Claude Code will make auto mode the default for new sessions on Pro, Max, and Team plans starting August 14, 2026. The mode routes tool calls through a safety classifier, keeps manual approval available, and no longer charges those plans for classifier overhead.
Claude Code Sessions Can Now Message Each Other
Claude Code now lets independent sessions discover and message one another. The feature supports local coordination on macOS and Linux, reply-only communication across machines or the web through Remote Control, and controls for holding, refusing, or approving incoming messages.
Claude Fable 5 Reduces Biology Fallbacks by About 85%
Anthropic says an update to Claude Fable 5's biology safeguards reduced biology-related fallbacks by about 85% in testing. Fable 5 can now handle a wider range of everyday health and educational questions, while dual-use professional biology and drug-development requests remain restricted.
MCP 2026-07-28 Moves to a Stateless Core as Claude Rolls Out Support
Anthropic says the MCP 2026-07-28 specification moves the Model Context Protocol from a bidirectional stateful design to a request/response model, adds versioned extensions for MCP Apps and Tasks, and aligns authorization with production OAuth 2.0 and OIDC deployments.
Claude Code artifacts can now call MCP connectors for live, viewer-specific data
Claude Code artifacts can call MCP connectors each time someone views them, so a published page shows current data rather than a session snapshot. Available on Pro, Max, Team, and Enterprise plans, requiring Claude Code v2.1.209 or later. Connector-backed artifacts cannot be shared to a public link on any plan.
Claude Code Desktop Adds an iOS Simulator Pane: Watch Claude Test Your App Live
Claude Code Desktop opens Apple's iOS Simulator in a pane beside your conversation when Claude builds or checks your app, taps through it, and reads the screen to verify its own changes. Public beta on macOS for Pro, Max, Team, and Enterprise plans; needs Claude Desktop v1.24012.0+ and Xcode 26.x, not Xcode 27.
Claude Code Ships Screen Reader Mode: Plain-Text TUI for VoiceOver and NVDA
Claude Code now has an opt-in screen reader mode that replaces boxes, spinners, and in-place redraws with labeled linear text that VoiceOver and NVDA read in order. Turn it on with the --ax-screen-reader flag, the CLAUDE_AX_SCREEN_READER env var, or the axScreenReader setting (v2.1.181+). Menus become numbered lists, a terminal bell signals when Claude needs you, and separate settings cover magnifiers, reduced motion, and colorblind themes.
Claude Adds Reflect: A Monthly Recap and Usage Dashboard for How You Use Claude
Anthropic introduced Reflect, a beta dashboard in Claude's Settings that shows a monthly recap of when you use Claude most and what you worked on, with quiet hours and break nudges. It runs only when memory is on, covers Free, Pro, and Max but not Team or Enterprise, and skips incognito chats, health integrations, Cowork, and Claude Code.
Claude Cowork Reaches Web and Mobile for Paid Plans
Claude Cowork is now available on web and mobile in beta for paid plans, so sessions can follow your Claude account across desktop, browser, and phone while work continues in the cloud.
Claude Code Artifacts Expand to Pro and Max Plans (Private by Default)
Anthropic's ClaudeDevs says Claude Code Artifacts are now available on Pro and Max plans. The Claude Code docs now list Pro/Max/Team/Enterprise as eligible, with Pro/Max artifacts remaining private to the individual user.
Anthropic raises Claude API rate limits and consolidates tiers into Start, Build, and Scale
Anthropic consolidated Claude Platform usage tiers into three -- Start, Build, and Scale -- and raised rate limits so Sonnet and Haiku match Opus at every tier. Tier placement is automatic, based on usage history rather than spend, but each tier still carries a monthly spend cap.
Claude Desktop for Linux Beta: Ubuntu and Debian, With Caveats
Anthropic shipped a beta of the Claude desktop app for Linux on Ubuntu 22.04+ and Debian 12+ (x86_64 or arm64). It gives the same Chat, Cowork, and Claude Code experience as macOS and Windows on all paid plans. Install via Anthropic's apt repo to get updates -- the app does not self-update, and a raw .deb install gets no updates. Computer Use and Dictation are not in the Linux beta yet, and only Debian-based distros are supported today.
Claude Science Beta: An AI Workbench for Reproducible Research
Anthropic launched Claude Science in public beta -- a research environment, not a model. It runs analyses, queries 60+ scientific databases, and traces every step from data wrangling to publication, with code, environment, and conversation provenance attached to each artifact. It runs on your own infrastructure (laptop, HPC, GPU clusters) and submits jobs over SSH to your own machines or HPC clusters, or through a Modal account. Available now on macOS and Linux for Pro, Max, Team, and Enterprise plans.
Claude Sonnet 5 Launch: Anthropic's Most Agentic Sonnet, Now the Default Tier
Anthropic launched Claude Sonnet 5 on June 30, 2026, calling it its most agentic Sonnet yet -- it plans, drives browsers and terminals, and runs autonomously. It is the default for Free and Pro, available across all plans, in Claude Code, and on the API as claude-sonnet-5. Anthropic later made its $2 per million input and $10 per million output token pricing permanent.
Claude Code Adds Artifacts: Live, Shareable Pages for PR Walkthroughs and Dashboards
Anthropic introduced Artifacts in Claude Code, letting Team and Enterprise orgs turn an in-progress Claude Code session into a live web page that updates as the session progresses and can be shared privately within the organization.
Claude Design's `/design-sync` Makes Claude Design and Claude Code a Two-Way Workflow
Anthropic's `/design-sync` pulls your design system into Claude Design so everything Claude builds starts from your real components, and keeps work synced as you move between Claude Design and Claude Code. You can start in either surface, hand a finished design off to Claude Code, and continue from existing work instead of a screenshot.
Anthropic Abruptly Suspends Fable 5 and Mythos 5 Access After US Government Directive
Anthropic says a US government export control directive ordered it to suspend all access to Claude Fable 5 and Mythos 5 by any foreign national, inside or outside the US. To comply, Anthropic is disabling both models for all customers. It says access to every other Anthropic model is unaffected, and that it is working to restore Fable 5 and Mythos 5 as soon as possible.
Claude Fable 5 and Mythos 5: Mythos-Class Capability Goes General, With Caveats
Anthropic launched Claude Fable 5, a Mythos-class model made safe for general use and available today as claude-fable-5, plus Claude Mythos 5 for vetted cyberdefenders via Project Glasswing. Pricing is $10 per million input and $50 per million output tokens, with free subscription access ending June 23 and a mandatory 30-day data-retention policy on all Mythos-class traffic.
Claude Platform's 'ant' CLI Brings the Full Claude API to Your Terminal
Anthropic's Claude Platform documents 'ant', a command-line tool that exposes every Claude API resource as a subcommand. It sends Messages requests, browses responses, version-controls agents and environments, and runs a self-hosted Managed Agents worker, with Claude Code able to drive it natively.
Claude Code adds dynamic workflows (research preview) for large parallel agent runs
Dynamic workflows in Claude Code let Claude write orchestration scripts, fan out work across tens to hundreds of parallel subagents, verify results, and resume long-running jobs.
Claude Opus 4.8 Fast Mode: 2.5x Faster Output Tokens in Research Preview
Anthropic launched Fast mode for Claude Opus 4.8 in research preview, promising 2.5x faster output token speeds with the same Opus-level intelligence. It is available now in Claude Code for developers with extra usage enabled, and on the Claude Platform API through an account manager or a waitlist form.
Claude Code ships a security-guidance plugin for in-session vulnerability checks
Anthropic shipped an official security-guidance plugin for Claude Code. It runs automatic vulnerability checks while Claude edits files, at the end of each turn, and when Claude runs commits or pushes through its Bash tool.
Claude Agent SDK Gets a Monthly Credit on Paid Claude Plans Starting June 15, 2026
Anthropic is bundling a dedicated monthly credit for programmatic Claude usage into Pro, Max, Team, and Enterprise plans starting June 15, 2026. The credit covers Claude Agent SDK projects, `claude -p` non-interactive Claude Code, Claude Code GitHub Actions, and third-party apps built on the Agent SDK, with amounts ranging from $20 on Pro to $200 on Max 20x and seat-based Enterprise Premium.
Claude Managed Agents Add Self-Hosted Sandboxes (Public Beta) and MCP Tunnels (Research Preview)
Anthropic says Claude Managed Agents can now run tool execution in a sandbox you control (public beta) and connect to private MCP servers via MCP tunnels (research preview). The update targets enterprise security requirements by keeping execution and private services within an organization's perimeter.
Claude Code 2.1.142: `claude agents` Gains Session Flags, Fast Mode Defaults to Opus 4.7, MCP Tool Timeout Honored
Anthropic shipped Claude Code 2.1.142 on May 14, 2026. The release adds eight session-configuration flags to `claude agents` (`--add-dir`, `--settings`, `--mcp-config`, `--plugin-dir`, `--permission-mode`, `--model`, `--effort`, `--dangerously-skip-permissions`), flips fast mode's default model from Opus 4.6 to Opus 4.7, and fixes `MCP_TOOL_TIMEOUT` not raising the per-request fetch timeout for remote HTTP/SSE MCP servers -- a regression that capped tool calls at 60 seconds regardless of configuration.
Claude Code Weekly Limits +50%: Promo Extended Through August 31, 2026
Anthropic's +50% Claude Code weekly-limits promo is still live, and Anthropic has now extended it a third time: its support doc runs the window through August 31, 2026 at 11:59 PM PT, not August 19. It covers Pro, Max, and Team plans plus legacy seat-based Enterprise, across the CLI, IDE extensions, desktop, and web.
Claude Code 2.1.133: `worktree.baseRef` Default Returns to `origin/<default>`, MCP OAuth Proxy Honored Across the Whole Flow
Anthropic shipped Claude Code 2.1.133 on May 7, 2026. The headline is a worktree-base behavior change: a new `worktree.baseRef` setting (`fresh` | `head`) defaults to `fresh`, which moves `EnterWorktree`'s base back to `origin/<default>` after several months of branching from local `HEAD`. The release also routes `HTTP(S)_PROXY` / `NO_PROXY` / mTLS through the entire MCP OAuth flow (discovery, dynamic client registration, token exchange, refresh), exposes effort level to hooks via `$CLAUDE_EFFORT`, adds Linux sandbox path overrides, and fixes a refresh-token race that was 401-ing parallel sessions.
Anthropic's Claude Code Post-Mortem: Three Engineering Missteps Behind the Spring 2026 Quality Decline
Anthropic published a post-mortem on April 23, 2026 explaining the Claude Code quality regression that ran from early March through mid-April: a March 4 default-effort downgrade from high to medium, a March 26 caching change that wiped reasoning history every turn, and an April 16 verbosity prompt that capped responses at 25 words between tool calls. All three were resolved by April 20, the API was unaffected, and Anthropic reset usage limits for all subscribers.
Claude Opus 4.7 Best Practices: How to Actually Get the Most Out of the Upgrade
Claude Opus 4.7 follows instructions more literally than 4.6, runs longer agentic tasks more reliably, and ships a new xhigh effort level. The practical effect: prompts that worked before may now produce surprises, and the workflows that earn the upgrade are the ones built around detailed plans, deliberate effort selection, auto mode with /fewer-permission-prompts, and explicit verification steps. Boris Cherny's day-of-launch tips are the honest playbook; this guide breaks them down with the workflows readers can apply this week.
Claude Design Launches: Anthropic Labs Turns Opus 4.7 Into a Prototype, Deck, and Wireframe Surface
Anthropic launched Claude Design on April 17, 2026 -- a research preview from Anthropic Labs that turns a prompt, uploaded image, or codebase into polished prototypes, pitch decks, and mockups. Powered by Claude Opus 4.7 vision, it learns your team's design system, exports to Canva, PDF, PPTX, or HTML, and packages finished designs for Claude Code handoff.
Claude Opus 4.7 Is Here: State-of-the-Art Coding, xhigh Effort, and a New Cyber Safeguards Tier
Anthropic launched Claude Opus 4.7 on April 16, 2026 -- a notable improvement on Opus 4.6 in advanced software engineering, with the same pricing, a new xhigh effort level, /ultrareview in Claude Code, higher-resolution vision, and the first deployment of cyber safeguards from the Mythos Preview track.
