Claude Desktop mcp deep_check

How to: Claude Desktop mcp deep_check

client:Claude Desktop transport:streamable-http tool:deep_check

Add mcp to Claude Desktop

01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://x402check.dev/mcp"
      ]
    }
  }
}

02
Save the file and restart Claude Desktop.
03
Ask for something deep_check does. Claude Desktop lists the server's tools on connect and calls deep_check itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that mcp'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

mcp will not start until these are set, so deep_check never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 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.
