Reviewed 19 July 2026 Canonical definition Part of: MCP & Agent Protocol Terms →

MCP server discovery is the process by which an AI client or agent learns which MCP servers are available, what capabilities they expose, and how to connect to them. Discovery can be static (pre-configured server lists), dynamic (registry-based lookups), or marketplace-driven. Discovery determines which tools an agent can reach at runtime, and therefore which actions it can take.
