## Connection (mcpServers)

```json
{
  "mcpServers": {
    "xguard": {
      "type": "http",
      "url": "https://xguardgate.com/mcp"
    }
  }
}
```


## Trust

- hygiene: 100
- liveness: 0
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo -unreachable(7 failures) ~updated-62d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 96/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### 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: 100 (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
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 981 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: 8, about 981 tokens to load them all
- tool set hash: e9b8464f3a1a21a5382bcc0d6febf11c
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.moelayyan90/xguard.svg)](https://protogrid.dev/servers/io.github.moelayyan90/xguard)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

## Tools (8)

- `xguard_discover`: Find the paid API catalog and buying instructions, plus explicit provider operations and input schemas.
- `xguard_execute`: Execute an explicit scoped provider operation, or a supported public-source outcome. intent:demo is free. Never infer a mutation from ambiguous text.
- `xguard_get_result`: Recover a paid public outcome with its payment identifier and original signed quote without execution or another payment.
- `xguard_preflight`: Inspect validation, scope and remaining capability budget without reserving, billing or executing. Execution rechecks everything.
- `xguard_quote`: Inspect XGuard credit pricing for a capability, or obtain a signed x402 quote for a public outcome. Does not execute.
- `xguard_secretless_call`: Call an allowed provider operation with a capability. Enforces scope, call/credit budget and billing before server-side credential injection. Writes require idempotency_key.
- `xguard_status`: Read observed execution/MCP metrics and configuration; empty observations do not imply uptime.
- `xguard_verify_receipt`: Verify a ProofRail proof and optionally its bound x402 receipt and result digest. Signature validity does not prove source truth.
