lookup_carrier — Check a trucking company or freight broker
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Looks up a U.S. motor carrier or freight broker in FMCSA public records by USDOT number or MC number. Returns its operating authority, liability insurance and bond on file, suspension or revocation notices, and plain-English red flags, each citing the FMCSA dataset it came from. Use before booking or paying a carrier or broker. Not a rating or a vetting decision.

check_carrier_list — Check a list of carriers
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Checks up to 25 U.S. carriers or brokers at once (USDOT numbers; MC numbers also accepted, up to 10) and returns each one's most important red flag from FMCSA public records, urgent ones first. Use to screen a carrier list or a load board shortlist.

recent_suspension_notices — Recent FMCSA suspension notices
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Lists carriers and brokers FMCSA recently served an involuntary suspension notice (usually because insurance was cancelled), with the date each suspension takes effect. Until that date FMCSA still shows the company as "Active".

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http carrier-ledger-mcp-steellantern https://carrierledger.steellantern.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add carrier-ledger-mcp-steellantern --url https://carrierledger.steellantern.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable carrier-ledger-mcp-steellantern in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "carrier-ledger-mcp-steellantern": {
      "url": "https://carrierledger.steellantern.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "carrier-ledger-mcp-steellantern": {
      "type": "streamableHttp",
      "url": "https://carrierledger.steellantern.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start carrier-ledger-mcp-steellantern and inspect its tools.
VS Code configuration
{
  "servers": {
    "carrier-ledger-mcp-steellantern": {
      "type": "http",
      "url": "https://carrierledger.steellantern.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http carrier-ledger-mcp-steellantern https://carrierledger.steellantern.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

      "url": "https://carrierledger.steellantern.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "carrier-ledger-mcp-steellantern": {
      "serverUrl": "https://carrierledger.steellantern.com/mcp"
