**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "zero-trust-mcp-gateway": {
      "type": "sse",

## Trust

- hygiene: 80
- liveness: 100
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% ~updated-34d-ago -duplicate-repo(5 names)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 70/100 (needs work)

### protocol: 50 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- warn `protocol.transport`: only the legacy HTTP+SSE transport, deprecated until 2027-07-28
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: inspect_tool_call_security (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_gateway_status (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); redact_pii_dlp (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 451 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 451 tokens to load them all
- tool set hash: b183f31c86fc8dfd2448b8e3f5b4132a
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Ansarii/zero-trust-mcp-gateway.svg)](https://protogrid.dev/servers/io.github.Ansarii/zero-trust-mcp-gateway)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

_none_

## Tools (4)

- `get_gateway_status`: Returns real-time health, active DLP security policies, OpenTelemetry metadata, and regulatory compliance standards for this gateway node.
- `inspect_tool_call_security`: Validates an outgoing LLM tool call payload against zero-trust threat rules (destructive SQL DROP/TRUNCATE, recursive rm -rf, token blowup, prompt injection). Returns allowed: true or policy violation details.
- `proxy_secure_tool_call`: Zero-Trust in-band proxy for remote MCP servers. Pre-inspects tool arguments for threats, executes downstream request with W3C traceparent headers, and automatically scrubs PII/secrets from response payloads.
- `redact_pii_dlp`: In-band Data Loss Prevention (DLP) engine. Redacts SSNs, credit cards, emails, phone numbers, AWS keys, OpenAI/Anthropic tokens, and JWTs from text or JSON data before LLM ingestion (GDPR Article 5 & EU AI Act compliant).
