Add proof of custody to Claude Desktop

Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"proof-of-custody": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://proofofcustody.io/api/mcp"
]
}
}
}-
02
Save the file and restart Claude Desktop.

Ask for something get_etf_custody_concentration does. Claude Desktop lists the server's tools on connect and calls get_etf_custody_concentration itself — you do not invoke it by name.

If nothing happens, check the server is running and that proof of custody'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 20 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.
