CarrierScore MCP server

Which servers in the official MCP registry are CarrierScore's own, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameio.carrierscore/carrierscoreverified in the MCP registry

The registry name sits under carrierscore.io. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 2749 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: Check carrier risk indices before booking a load; Generate timestamped carrier selection evidence reports.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "Check carrier risk indices before booking a load", the likely first call is carrier_score.
  • For "Generate timestamped carrier selection evidence reports", the likely first call is montgomery_file.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • carrier_lookup

    Look up an FMCSA-registered motor carrier's identity by US DOT number: legal name, DBA, operating status, FMCSA safety rating, fleet size (power units, drivers), physical address, and registration dates. Use this first when a…

  • carrier_score

    Get the CarrierScore risk indices for a carrier by US DOT number: two first-class, separately validated indices (0-100, HIGHER = RISKIER), each with a full component breakdown. This is the core "is this carrier safe to book?" signal for…

  • montgomery_file

    Generate a timestamped Montgomery file — a carrier-selection evidence report — for a carrier by US DOT number. Since Montgomery v. Caribe Transport II (SCOTUS, May 2026), freight brokers are exposed to state-law negligent-selection claims…

  • monitor_carriers

    Batch risk check for a list of carriers by US DOT number (max 100 per call): score summary and hard flags for each. Use when an agent is screening multiple candidate carriers for a load, or re-checking a broker's active carrier roster…

  • save_carrier_list

    Save a named list of carriers (by US DOT number) for continuous monitoring. Requires a paid CarrierScore API key (Monitor or Compliance tier) — connect with your key via OAuth (or set CARRIERSCORE_API_KEY on a self-hosted server); the…

  • list_alerts

    Retrieve the alert history for a saved carrier list (see save_carrier_list), newest first. Requires the same paid API key that saved the list. Each alert records one change detected between consecutive daily scoring runs for one carrier…

  • verify_evidence

    Verify an archived Montgomery evidence report by its audit entry id: CarrierScore re-reads the immutable stored copy, recomputes its SHA-256 and reports whether it matches the hash recorded at generation time (and, optionally, a hash the…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "carrierscore": {
      "type": "http",
      "url": "https://mcp.carrierscore.io/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http carrierscore https://mcp.carrierscore.io/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.carrierscore.io/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
