Claude Desktop FineRx get_savings_card
How to: Claude Desktop FineRx get_savings_card
Add FineRx to Claude Desktop
-
01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"finerx": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://www.finerxfinder.com/mcp"
]
}
}
}-
02
Save the file and restart Claude Desktop.
-
03
Ask for something get_savings_card does. Claude Desktop lists the server's tools on connect and calls get_savings_card itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that FineRx'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
FineRx will not start until these are set, so get_savings_card never becomes available.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
