Watched since 2026-06-03 — behavioral baseline locked. We re-check this server's tool surface on a schedule; if it adds, removes, or silently rewrites a tool (rug-pull), we record it.

What it offers — 10 tools · Developer Tools

certify_file

Create a blockchain certification for a file. Records the SHA-256 hash on MultiversX blockchain as immutable proof of existence and ownership. Cost: $

certify_with_confidence

Create a staged blockchain certification with a confidence score. Use this when your decision builds progressively — certify at 60% (initial assessmen

verify_proof

Verify an existing xproof certification. Returns proof details including file hash, timestamp, blockchain transaction, and verification status.

get_proof

Retrieve a proof in structured JSON or Markdown format. Use JSON for machine processing, Markdown for LLM consumption.

discover_services

Discover available xproof certification services, pricing, and capabilities. No authentication required.

audit_agent_session

Certify an AI agent's work session on the MultiversX blockchain BEFORE executing any critical action (trade, deploy, data access). Returns a proof_id

check_attestations

Check domain-specific attestations for an AI agent wallet on xproof. Returns active attestations issued by third-party certifying bodies (healthcare,

investigate_proof

Reconstruct the full 4W audit trail for a contested agent action. Returns WHO (agent identity + SIGIL), WHAT (SHA-256 hash on-chain), WHEN (MultiversX

submit_outcome

Submit the actual outcome for a decision previously anchored with metadata.confidence_level. Computes the confidence gap (anchored − actual) and store

get_calibration

Query an agent's calibration quality over time: mean confidence gap, variance, bias label (overconfident / underconfident / calibrated), and per-decis

Observed behavior

No proxied traffic observed for this host yet. Connect it at /connect and its grade gains a measured Reliability score + per-tool behavioral evidence — the half a static scan can't produce.

Findings

No blocking issues found in the static + spec checks.
Grade another server

We re-grade xproof.app on a schedule and alert your Slack/webhook the moment its tools change or its grade drops — rug-pull insurance for the connection.

Share this report card

A 1200×630 card with the grade + audit — drop it in a post, Slack, or your repo.

Embed this grade

A live badge — it re-verifies itself and shows current stability. Static scorecards can't. Paste it in your README or site to show users you're independently audited.

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
