Microsoft Copilot (Microsoft 365): Dynamic Tool Discovery for Declarative Agents and Federated Copilot Connectors

We’re introducing dynamic tool discovery for declarative agents in Microsoft 365 Copilot. Developers can now add, update, or retire tools on their MCP servers without republishing the agent – so end users get the latest agent capabilities immediately, with no deployment cycle in between. Support for federated Copilot connectors will be a fast follow to declarative agents at a later stage. Dynamic tool discovery is backed by Microsoft’s enterprise RAI and security protections, and customers retain full control over agent deployment and availability to users and groups.
