Claude Desktop Arca Life Sciences fetch_source_record
How to: Claude Desktop Arca Life Sciences fetch_source_record
Add Arca Life Sciences to Claude Desktop
-
01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"life-sciences": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://app.arca.inc/api/public/mcp"
]
}
}
}-
02
Save the file and restart Claude Desktop.
-
03
Ask for something fetch_source_record does. Claude Desktop lists the server's tools on connect and calls fetch_source_record itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Arca Life Sciences'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
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 6 November 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.
