- name: io.github.ExpertVagabond/universal-blockchain
- version: 1.0.2
- connection class: L0 (run_local_package)
- trust: 76/100
- quality: –/100 (not scored)
- owner: not claimed
- descriptor: https://api.protogrid.dev/v1/servers/io.github.ExpertVagabond%2Funiversal-blockchain

**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": {
    "universal-blockchain": {
      "command": "npx",
      "args": [

## Trust

- hygiene: 100
- liveness: n/a
- freshness: 45
- provenance: 80
- drivers: +repository +namespace-matches-repo ~liveness-unmeasured -stale-248d
- 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`: 31 advisories to act on (malicious, or rated high or critical with a fix available): GHSA-7q85-xj36-vmfc in adm-zip@0.4.16 (indirect, fixed in 0.6.1), GHSA-8238-w5pm-2374 in adm-zip@0.4.16 (indirect, fixed in 0.6.1), GHSA-j5f4-cc29-5x44 in adm-zip@0.4.16 (indirect, fixed in 0.6.1), ...; 37 more of lower severity or without a fix
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.17.4 has 4 known advisories (GHSA-345p-7cg4-v4c7, GHSA-6qxp-vccf-f47h, GHSA-8r9q-7v3j-jr4g, ...); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: universal-blockchain-mcp@1.0.2 resolved: 1127 packages

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