Grok iana registries mcp server iana_lookup_http_field
How to: Grok iana registries mcp server iana_lookup_http_field
Add iana registries mcp server to Grok
-
01
Open .mcp.json (in your project root) and merge this in. Keep any servers already there.
{
"mcpServers": {
"iana-registries-mcp-server": {
"type": "http",
"url": "https://iana-registries.caseyjhand.com/mcp"
}
}
}-
02
Save the file and restart Grok.

03
Ask for something iana_lookup_http_field does. Grok lists the server's tools on connect and calls iana_lookup_http_field itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that iana registries mcp server's identifier in your config matches the one above exactly.
Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
Set these first
iana registries mcp server will not start until these are set, so iana_lookup_http_field never becomes available.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 2 October 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
