Claude Desktop fcc-spectrum-mcp-server fcc_spectrum_list_reference
How to: Claude Desktop fcc-spectrum-mcp-server fcc_spectrum_list_reference
Add fcc-spectrum-mcp-server to Claude Desktop
-
01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"fcc-spectrum-mcp-server": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://fcc-spectrum.caseyjhand.com/mcp"
]
}
}
}-
02
Save the file and restart Claude Desktop.
-
03
Ask for something fcc_spectrum_list_reference does. Claude Desktop lists the server's tools on connect and calls fcc_spectrum_list_reference itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that fcc-spectrum-mcp-server's identifier in your config matches the one above exactly.
Claude Desktop has no remote transport in its config file, so this bridges through mcp-remote. Restart the app after saving. Claude Desktop docs
Set these first
fcc-spectrum-mcp-server will not start until these are set, so fcc_spectrum_list_reference 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.
