- connection class: L0 (run_local_package)
- trust: 76/100
- quality: –/100 (not scored)

**Runs on your machine: something must execute the package.** Only local packages are published (npm, PyPI, OCI, …). The registry never executes them, so tools are unknown until you run it.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "paypal-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@paypal/mcp@1.8.1"
      ],
      "env": {
        "PAYPAL_ACCESS_TOKEN": "${PAYPAL_ACCESS_TOKEN}",
        "PAYPAL_ENVIRONMENT": "${PAYPAL_ENVIRONMENT}"
      }
    }
  }
}
```

Placeholders to fill: `${PAYPAL_ACCESS_TOKEN}`.

## Trust

- hygiene: 100
- liveness: n/a
- freshness: 45
- provenance: 80
- drivers: +repository +namespace-matches-repo ~liveness-unmeasured -stale-357d
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality –/100 (not scored)

Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### 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: n/a (weight 30)

- n/a `tools.descriptions`, `tools.description_length`, `tools.schemas`, `tools.annotations`, `tools.directory_hints`, `tools.token_cost`, `tools.api_dump`: tool list unknown (behind auth, not probed, or empty)

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

- n/a `stability.changes`, `stability.rug_pull`: tool list unknown

### dependencies: 33 (weight 15)

- fail `deps.known_vulns`: 5 advisories to act on (malicious, or rated high or critical with a fix available): GHSA-j4fx-xxwh-2485 in jsondiffpatch@0.6.0 (indirect, fixed in 0.7.6), GHSA-r399-636x-v7f6 in @langchain/core@0.3.6 (indirect, fixed in 0.3.80), GHSA-3644-q5cj-c5c7 in langsmith@0.1.68 (indirect, fixed in 0.6.0), ...; 6 more of lower severity or without a fix
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: @paypal/mcp@1.8.1 resolved: 250 packages

- tools: unknown
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.paypal/paypal-mcp-server.svg)](https://protogrid.dev/servers/io.github.paypal/paypal-mcp-server)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
