Claude Desktop Form4API — SEC Insider Trading check_usage

How to: Claude Desktop Form4API — SEC Insider Trading check_usage

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

Add Form4API — SEC Insider Trading to Claude Desktop

  1. 01

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

{
  "mcpServers": {
    "form4api-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.form4api.com/mcp"
      ]
    }
  }
}
  1. 02

    Save the file and restart Claude Desktop.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Form4API — SEC Insider Trading'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

Form4API — SEC Insider Trading will not start until these are set, so check_usage never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 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.
