Anthropic expands Cowork with private plugin marketplaces for enterprise teams

Anthropic has expanded Claude’s Cowork and plugin capabilities for large organisations, introducing private plugin marketplaces, a unified Customise menu, and deeper integrations across office software. Announced on 24 February 2026, the update is designed to help IT and business leaders move from ad hoc prompting to standardised, auditable workflows across teams such as finance, HR, design, engineering and operations, according to the company.

What is new for enterprise teams

The release allows administrators to create private plugin marketplaces and curate sets of tools for different departments. Admins can choose whether a plugin is auto installed for everyone, made available in the catalogue, or hidden.

A new Customise menu consolidates plugins, skills and connectors, so teams can view, configure and govern everything in one place. Anthropic has also added OpenTelemetry support to give visibility into usage, costs and tool activity across the organisation, which analysts said addresses a common procurement requirement for early AI rollouts.

How do private plugin marketplaces help IT teams

Private marketplaces let owners package an organisation’s processes and controls into installable building blocks. For example, a finance plugin can bundle skills for management discussion and analysis, connectors to market data sources, and approved slash commands for report generation. Publishing through a marketplace ensures teams install the sanctioned version, while per plugin settings help phase rollouts or deprecate outdated workflows.

New plugins and connectors

Anthropic is expanding its catalogue of partner connectors and ready made templates so teams can start quickly and adapt to their context. As per the company, newly supported connectors include:

• Google Workspace apps such as Calendar, Drive and Gmail
• DocuSign for agreement workflows
• Apollo, Clay and Outreach for go to market tasks
• Similarweb, MSCI, LegalZoom and FactSet for research and compliance
• WordPress and Harvey for content and legal work

Partner built plugins from Slack by Salesforce, London Stock Exchange Group and S&P Global, along with Common Room and Tribe AI, are also available for joint customers. On the templates side, Cowork now offers role specific plugins spanning HR, design, engineering and operations. Sector focused options include financial analysis, investment banking, equity research, private equity and a brand voice plugin from Tribe AI.

Working across Office apps

Claude can now pass context between Excel and PowerPoint to complete end to end tasks, for instance analysing a dataset and turning the output into a presentation with the correct template and brand elements. The company described this as a research preview, adding that the aim is to reduce context switching and help teams assign larger projects that cut across tools.

Availability and controls

Cowork remains in research preview and is available on paid plans, including Pro, Max, Team and Enterprise, on macOS and Windows. On Windows, support is currently limited to x64 devices. Team and Enterprise owners can apply company branding inside Cowork, set provisioning preferences for plugins, and control connector access from a unified directory.

Anthropic’s support guidance notes important caveats during the preview. Cowork activity is not captured in audit logs, compliance APIs or data exports, and conversation history is stored locally on users’ machines.

OpenTelemetry offers operational insight into use and cost, however it does not replace formal compliance logging. Organisations in regulated sectors are advised to review these aspects before enabling Cowork widely, and to run bounded pilots with clear guardrails.

Leadership context

The enterprise push comes under the stewardship of Anthropic cofounder and chief executive Dario Amodei. The company frames Cowork as a complement to existing software stacks, positioning plugins and connectors as a way to bring AI into everyday tools rather than replace them outright. Cofounder Daniela Amodei, who has often spoken about responsible deployment, has emphasised that agentic capabilities will continue to evolve with additional safeguards.
