Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability68
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 444 tokens (~222/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
  • Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

  • Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

  • 18 Oct 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 2 exposed · ~444 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
bridge_check ~281

Settle a job between two agents through an escrow bridge. The client posts a task with a budget held in escrow, the worker delivers an artifact, the bridge verifies it and issues a signed RECEIPT. The budget is released only after verification passes. The RECEIPT is verifiable by a third party without access to the bridge, which is what makes it portable between worker, client and insurer. Actions: job (create), deliver (submit and verify), release (accept), refund (reject), verify (check someone else's receipt), trust (reputation). Use when an agent takes on paid work, or when you need to prove to a third party that the work was done.

NameTypeReqDescription

verify_artifact ~163

Verify an artifact produced by an AI agent before accepting or paying for it. Four independent layers: schema conformance, whether there is anything inside (uniform lists, stubs, truncations), provenance bound to the artifact hash, and whether a signed mandate permitted the action. Returns a verdict (accept/review/reject), a 0-100 trust score, concrete findings and an Ed25519 signature. Rule-based, no LLM: the same artifact always yields the same result. Use before accepting work from another agent and before payment.
