Schema Quality & AI Usability69
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 378 tokens (~75/item across 5 items; 5 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage67
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

    No change was recorded against any check on this day. Stability & Change Management went from 43 to 47. That category is still filling its 30-day observation window: 13 days of observed history at the previous scan, 14 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 5 exposed · ~378 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 →

Tool Tokens
carrier_record ~119

Qualify a USDOT number and an as-of date: whether this archive can answer for them, what each source holds for the period, and what a purchased record could establish. It returns no row of the record. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.

carrier_record_by_docket ~120

Qualify a docket number and an as-of date: whether this archive can answer for them, what each source holds for the period, and what a purchased record could establish. It returns no row of the record. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.

Input schema present but exposes no named parameters.

Return one published specimen. A specimen is a sample with the carrier withheld, not an issued record.

verify ~82

Verify a Substradium fingerprint. The answer names neither the carrier nor the customer. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.
