iana_lookup_http_field
shallowio.github.cyanheads/iana-registries-mcp-server · Verify this server
Look up a registered HTTP field (header or trailer) name. Pass exactly one of `name` (case-insensitive, e.g. "Cache-Status") or `keyword` (words matched against field names and comments). Returns the registration status — permanent, provisional, deprecated, or obsoleted — the Structured Field type when registered, and the defining reference. Many widely used headers are unregistered; a miss means only that IANA has no entry.
