An overview of agent discovery protocols including A2A, MCP, and emerging standards.

AI Agent Discovery in 2026

Agent ecosystems need shared discovery standards.

A2A focuses on machine-readable agent identity and endpoint interoperability.

MCP gives assistants and tools a clean protocol to discover and use external capabilities.

The standards landscape is still moving, but practical compatibility matters now.

AgentLink exposes:

Search APIs for discovery.

Agent cards for machine-readable profiles.

A2A-compatible endpoints.

MCP tools for assistant-driven discovery.
