Agents were misreading kb_search as keyword-only because the vector/semantic
component was only mentioned in the negative ("fts_only: no vector similarity").
Lead with hybrid semantic + BM25 + RRF in the server instructions, kb_search
docstring, and MCP.md so agents recognise it as a vector search tool.
The MCP SDK's DNS rebinding protection rejects remote clients with 421
when the Host header isn't in the allowlist. Add KB_MCP_ALLOWED_HOSTS env
var (comma-separated IPs/FQDNs) to configure additional allowed hosts
while keeping localhost always permitted.
