Merge Launches Agent Handler on the Microsoft Agent Store, Expanding Agent Connectivity Across the Microsoft 365 Ecosystem

Merge, the connective infrastructure for production AI, announced today that Merge Agent Handler will be available on the Microsoft Agent Store, providing every agent built on Microsoft 365 with secure, governed access to hundreds of third-party business applications.

Today's most capable agents can take action within the tools they're embedded in, like summarizing a meeting, drafting an email, or reasoning over a document. The next level of agent productivity is the ability to take action across external systems, like updating a record in Workday, opening a ticket in Jira, or logging an opportunity in Salesforce. To enable that, companies need a secure, managed infrastructure layer optimized for AI agents to access and take action in business systems. Merge built Agent Handler to be that layer, and chose to bring it to the Microsoft Agent Store because Microsoft 365 is where most enterprise users already work with AI every day.

"We've entered the action era of enterprise AI. The limit is no longer model quality — it's action, and the companies that win will be the ones whose agents can actually do the work, not just talk about it," said Shensi Ding, co-founder and CEO of Merge. "By making Merge Agent Handler available on the Microsoft Agent Store, we're giving every Microsoft 365 customer a single, governed front door to the systems that run their business."

When Agent Handler arrives on the Microsoft Agent Store, administrators will be able to install it once and immediately enable Model Context Protocol (MCP) connectivity to hundreds of business applications spanning HR, CRM, applicant tracking, accounting, ticketing, file storage, and more for all employees.

Agent Handler is built to meet the bar enterprise security teams set for production AI. It's SOC 2 Type II, HIPAA, and ISO 27001 compliant, with SSO/SCIM support, role-based access controls, and data loss prevention layers built in. Security teams can define exactly which actions an agent is allowed to take in each downstream system, and every read and write is captured in immutable audit logs. Agents working inside Microsoft 365 Copilot, Teams, Outlook, Word, and Excel can discover available actions, execute them under the right scopes, and feed the results back into Microsoft 365 workflows, with consistent governance across every surface.

"Our partner ecosystem is one of the ways customers extend Microsoft 365, and integrations are one of the hardest pieces of any production agent rollout," said Chantrelle Nielsen, Principal Product Management for Microsoft 365 Copilot, Microsoft. "Working with Merge to bring Agent Handler to the Microsoft Agent Store gives our shared customers a clear path to take their agents from conceptual to operational."

For Microsoft 365 Copilot customers, the result will be a step change in what agents can do. On day one of availability, an enterprise will be able to connect once and open agent-driven actions across talent systems (Workday, Greenhouse, Ashby), customer and revenue systems (Salesforce, HubSpot, Zendesk), finance and accounting systems (NetSuite, QuickBooks, Xero), collaboration systems (Google Drive, Box, Dropbox), and more. IT and security leaders will be able to set guardrails on which actions agents can perform, and monitor every agent invocation from a single console.

Bringing Agent Handler to the Microsoft Agent Store marks an ambitious expansion of Merge's footprint. Merge already powers integrations for OpenAI, Perplexity, Netflix, Dropbox, Ramp, and thousands of other AI and enterprise software companies. Extending that same connectivity layer to Microsoft 365 Copilot customers gives organizations across every industry a path to put agents to work against the systems that already run their business.

Merge Agent Handler is expected to arrive on the Microsoft Agent Store in the coming weeks. Customers interested in early access can register at merge.dev/copilot-connector.
