Automated checks

StatusCheckPolicyResult
PASS Listed on the official MCP registry §1.1
Listed on registry.modelcontextprotocol.io as cloud.redu/mcp. 1 finding
  • Registry entry: cloud.redu/mcp ↗
WARN Source repository is public and maintained §1.2

No public source repository could be identified for this server.
INFO Published package is consistent and attested §1.3

No published package associated with this server (remote-only or non-npm/PyPI source).
PASS Tool surface is inspectable and proportionate §2.1–§2.4
73 tool(s) enumerated. Capabilities detected: filesystem, process-execution. Reported as capability risk (§2.4); whether each is essential to the server's stated purpose is §2.3 and remains a manual judgement. 6 findings
  • Tools exposed: 73
  • upgrade_to_cluster: filesystem
  • get_ssh_command: process-execution
  • restore_backup: filesystem
  • detach_volume: filesystem
  • Detected capabilities: filesystem, process-execution
PASS HTTPS-only endpoint §3.1
Endpoint uses HTTPS. 1 finding
  • Endpoint: https://mcp.redu.cloud/mcp
UNVERIFIABLE Authentication required §3.2

Endpoint rejected the probe (HTTP 400); whether it requires authentication could not be determined.
PASS OAuth protected-resource metadata published §3.3
Publishes /.well-known/oauth-protected-resource per the June 2025 authorization spec. 1 finding
  • Authorization server: https://login.redu.cloud/realms/eu-central-1
INFO No known vulnerabilities (OSV.dev) §4.1

No package to query (remote-only server).
WARN Server-supplied instructions free of poisoning indicators §5.1–§5.4
4 suspicious indicator(s) found in server-supplied instructions, tool descriptions, or schemas. 4 findings
  • server instructions: oversized: 10192 chars (limit 4096)
  • plan_deploy description: oversized: 2295 chars (limit 2048)
  • upgrade_to_cluster description: oversized: 3405 chars (limit 2048)
  • create_clickhouse: embedded URL: http://host:8123
What this grade covers
  • Provenance & supply-chain integrity (§1)
  • Tool surface & capability risk (§2)
  • Transport & authentication (§3)
  • Known CVEs via OSV.dev (§4)
  • Instruction/tool poisoning patterns (§5)

Limitations: pattern-based only (no semantic injection detection), static npm analysis (live server instructions not retrieved for package-only scans), single-server scope (no cross-server toxic flow analysis). See the full policy.
