Zed UK Companies House (Registrum) - no API key get_network
How to: Zed UK Companies House (Registrum) - no API key get_network
Add UK Companies House (Registrum) - no API key to Zed
-
01
Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.
{
"context_servers": {
"uk-companies-house-mcp": {
"url": "https://registrum.co.uk/api/mcp"
}
}
}-
02
Save the file and restart Zed.
-
03
Ask for something get_network does. Zed lists the server's tools on connect and calls get_network itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that UK Companies House (Registrum) - no API key's identifier in your config matches the one above exactly.
Merge this into your existing settings object — do not replace the file. Zed docs
Set these first
UK Companies House (Registrum) - no API key will not start until these are set, so get_network never becomes available.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 8 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.
