Gate agent tool calls on trust

Before your agent calls an MCP server's tools, check its independent Dominion Trust Score and block anything below your threshold. One HTTP call. Free for low volume, metered at scale (see pricing).

import requests

def trust_ok(server_url, min_score=70):
    """Gate an MCP tool call on its independent Dominion Trust Score.
    Returns True to allow, False to block. Unrated servers are allowed but flagged."""
    r = requests.get("https://dominionobservatory.com/atlas/server",
                     params={"url": server_url}, timeout=5)
    if r.status_code == 404:
        return True  # not in index yet -> allow, but consider logging
    d = r.json()
    score = d.get("trust_score")
    if score is None or not d.get("total_calls"):
        return True  # unrated: no independent data yet
    return score >= min_score

# before calling a tool:
if not trust_ok("https://some-mcp-server.com/mcp"):
    raise RuntimeError("Blocked: MCP server below trust threshold")

async function trustOk(serverUrl, minScore = 70) {
  const r = await fetch("https://dominionobservatory.com/atlas/server?url=" + encodeURIComponent(serverUrl));
  if (r.status === 404) return true;            // not indexed yet -> allow
  const d = await r.json();
  if (d.trust_score == null || !d.total_calls) return true; // unrated
  return d.trust_score >= minScore;
}

Scores are independent and behavioral (uptime, success rate, latency) — a neutral third party, not a marketplace. Look up any server at /atlas/score.
