Updates: #Claude Platform.

[NEW] Claude Marketplace: one place to discover plugins, agents, and services · On September 23, 2026, Anthropic launched Claude Marketplace, bringing plugins and connectors, agents and products, and service partners into one place. Choose from more than 2,000 connectors and plugins, and use a portion of your committed Anthropic spend on Claude-powered software from partners.

[NEW] Building commerce agents with Claude · Anthropic released a blueprint for building commerce agents on Claude on September 2, 2026. It ships two agents defined once and deployable three ways — a shopping agent for customers and a merchant agent for staff, running on the Messages API, the Claude Agent SDK, or Claude Managed Agents — along with four runnable vertical examples covering retail, travel, telecom, and entertainment. A Claude Code plugin called commerce-builder scaffolds a custom agent for your own store. The code is available under Apache License 2.0 at anthropics/commerce-agents, and every example runs on fictional data with no live orders or charges.

[NEW] Computer use, the Skills API, and the Files API are now generally available — plus a new browser use tool · Computer use, the Skills API, and the Files API are now generally available on the Claude Platform, alongside a new browser use tool for web applications. Computer use now executes multiple actions per turn instead of one per model call and is eligible for HIPAA-regulated workloads under Anthropic's BAA. The Skills API gets a simplified upload and versioning interface, and the Files API adds automatic expiration, 5x higher rate limits, and 1 TB of storage per organization.

[NEW] Bringing MCP 2026-07-28 to Claude — a stateless core, standardized extensions, and hardened auth · MCP 2026-07-28, the fifth spec release of the Model Context Protocol, is live. It moves MCP from a bidirectional stateful protocol to a stateless request/response core so servers can deploy on serverless and edge infrastructure, graduates MCP Apps and Tasks into a versioned extensions framework, and aligns authorization with production OAuth 2.0 and OIDC deployments. Support is rolling out across Claude products.

[NEW] Claude in Microsoft Foundry is now generally available · Claude models are now generally available in Microsoft Foundry, hosted on Azure. Claude runs in your Azure environment with the authentication, billing, and governance controls your teams already use, and you can choose where inference is processed, including a US data zone for teams with data residency requirements. Claude Opus 4.8 and Claude Haiku 4.5 are available, with support for the Messages API, prompt caching, and extended thinking.

[NEW] Workload Identity Federation is now generally available on the Claude Platform · Workload Identity Federation is generally available on the Claude Platform, letting developers authenticate with short-lived, scoped credentials from OIDC-compliant identity providers instead of static API keys. Federation rules bind external identities — AWS IAM, GCP, Azure, Kubernetes, GitHub Actions, Okta — to service accounts that issue tokens at request time across all Claude API endpoints.

[NEW] Claude Managed Agents — Self-hosted sandboxes and MCP tunnels · Claude Managed Agents now supports self-hosted sandboxes (public beta) and MCP tunnels (research preview). The agent orchestration loop stays on Anthropic infrastructure while tool execution runs in customer infrastructure or with managed sandbox providers — Cloudflare, Daytona, Modal, Vercel — and agents reach private-network MCP servers through a lightweight gateway with a single outbound connection, no inbound firewall rules required.

[NEW] Claude Platform on AWS is now generally available · The Claude Platform on AWS — Anthropic-operated, accessed via AWS IAM with CloudTrail audit logging and a single AWS invoice — is generally available. AWS customers get day-one access to all native Claude API features, including Claude Managed Agents (beta), Advisor strategy (beta), Files API (beta), Skills (beta), and the MCP connector (beta), with Claude Opus 4.7, Sonnet 4.6, and Haiku 4.5 available at launch.

[NEW] Claude Platform on AWS Announced (Coming Soon) · AWS announced Claude Platform on AWS — a new way to use Anthropic's native Claude Platform with AWS credentials, billing, and access controls. It sits alongside Claude on Amazon Bedrock as a second path with different data-residency tradeoffs.
