Advertise the Kernel server name on initialize

[masnwilliams]

Summary

The MCP server was identifying itself to every client as mcp-typescript server on vercel — mcp-handler's default serverInfo, which we never overrode. server.json already declares the server as com.onkernel/kernel-mcp-server, so the registry entry and the runtime handshake disagreed.

This passes serverInfo through to createMcpHandler, sourced from server.json so the two can't drift apart again.

Clients now see:

"serverInfo": { "name": "com.onkernel/kernel-mcp-server", "version": "1.0.0" }

serverInfo.name is the programmatic identifier (per spec, clients prefer an optional title for display and fall back to name); mcp-handler's ServerOptions type only accepts name and version, so title is out of scope here.

Why it matters beyond cosmetics

• Registry consumers and bundle tooling expect the manifest name to match the serverInfo.name returned by initialize.
• The name is recorded on captured analytics events, so every event to date is attributed to a generic default rather than to this server.

Verification

Ran the real route locally and probed POST /mcp:

• initialize returns serverInfo: { name: "com.onkernel/kernel-mcp-server", version: "1.0.0" }.
• With a project token set, the captured $mcp_initialize and $mcp_tools_list events carry $mcp_server_name = com.onkernel/kernel-mcp-server and $mcp_server_version = 1.0.0, grouped in one session with client name and version intact.

tsc --noEmit and prettier --check pass. No behavior change to tools, auth, or transport.

Note

Low Risk
Single configuration pass-through on handler creation with no changes to auth, tools, or request handling.

Overview
MCP handshake identity now matches the registry manifest: createMcpHandler is given { serverInfo: { name, version } } imported from server.json, so clients get com.onkernel/kernel-mcp-server / 1.0.0 on initialize instead of mcp-handler's generic default.

This keeps registry consumers, analytics attribution ($mcp_server_name / version), and the runtime handshake aligned without duplicating those fields elsewhere. Auth, tools, and transport behavior are unchanged.
