    No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 3 exposed · ~263 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Install

How do I install the CarrierTrail MCP server?

CarrierTrail is a hosted endpoint at https://carriertrail.com/mcp/v1, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Is the CarrierTrail MCP server safe to use?

CarrierTrail scores 71 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the CarrierTrail MCP server expose?

CarrierTrail exposes 3 tools: search_carriers, get_carrier, get_recent_changes. Their descriptions and schemas cost roughly 263 tokens of context every time the server is loaded.

Does the CarrierTrail MCP server require authentication?

No. We connected to CarrierTrail without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the CarrierTrail MCP server still maintained?

CarrierTrail is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
