MCP Dev Summit Seoul 2026

10,000+ MCP servers exist. Developers can't find them. Agents can't query them at runtime. There is no canonical, vendor-neutral, machine-readable registry, and that single gap is slowing MCP adoption more than any protocol limitation.

This talk dissects the MCP discoverability crisis: why a fragmented landscape of marketplace-style lists, hand-curated JSON files, and closed vendor directories fails both human developers and autonomous agents. Drawing on the DNS, npm, and Docker Hub precedents, I propose an open MCP Registry Specification covering four layers: server schema contracts, semantic capability metadata for runtime agent discovery, cryptographic provenance attestation, and a federated hosting model any organization can self-host.

We'll walk through a working prototype of a registry server that conforms to the proposed spec, federate it with a second node live, and demonstrate a Claude agent autonomously discovering and connecting to previously unknown MCP servers via semantic query. No proprietary platform required.
