Anthropic launches ten new plugins Cowork and Microsoft 365 integrations for financial agents

Anthropic presented a package of ten new Cowork plugins, as well as integrations with Microsoft 365, specialized connectors and an MCP application, all focused on AI agents in the financial sector. The novelty promises to automate complex tasks, such as data reconciliation, risk analysis and compliance, directly in corporate environments.

What Cowork and Claude plugins are Code for financial AI?

Cowork plugins are extensions that allow AI agents to interact with financial systems such as ERPs and trading platforms. Claude Code, in turn, is a development tool that integrates the Claude 3.5 Sonnet model — already recognized for its ability to handle up to 200,000 tokens — directly in coding and automation flows. Together, they allow finance teams to automate from reporting to execution of transactions.

Microsoft 365 integrations: how they work in Cowork plugins

Microsoft 365 integrations connect AI agents to tools like Excel, Outlook, and SharePoint. This means that an agent can, for example, extract data from emails, update spreadsheets automatically and schedule audit meetings — all without direct human intervention. Anthropic points out that this reduces manual errors and accelerates processes that used to take hours.

Why do Cowork plugins matter to the financial sector?

Financial institutions deal with large volumes of regulated data, where accuracy and speed are critical. The new connectors and the MCP (Model Context Protocol) application allow agents to access bank APIs and payment systems safely, respecting compliance. According to Anthropic, the proposal is to turn the agent into a "virtual analyst" who operates within the business rules.

New connectors and MCP application for financial agents

Announced connectors include integrations with platforms such as Salesforce Financial Services Cloud and payment systems. The MCP application functions as a central hub that manages permissions and contexts for each agent, ensuring that it only accesses authorized information. This architecture is especially relevant for Brazil, where the regulation of financial data (LGPD) requires granular control.
