app.undisk.mcp/stdio-proxy
This directory entry reports an automated security scan of app.undisk.mcp/stdio-proxy, scanned 2026-07-28. Trust grade C rates provenance, transport, known vulnerabilities and instruction integrity; capability risk is reported separately, not folded into the grade.
Automated checks
| Status | Check | Policy | Result |
|---|---|---|---|
| PASS | Listed on the official MCP registry | §1.1 | Listed on registry.modelcontextprotocol.io as app.undisk.mcp/stdio-proxy. 1 finding
|
| WARN | Source repository is public and maintained | §1.2 | Repository health issues: no license. 5 findings
|
| FAIL | Published package is consistent and attested | §1.3 | Integrity concerns: package repository field does not match the claimed source repo; no npm provenance attestation. 6 findings
|
| PASS | Tool surface is inspectable and proportionate | §2.1–§2.4 | Package source scanned; no high-risk capability signals. 1 finding
|
| INFO | Transport & authentication | §3 | Local (stdio) server: runs with host-process privileges by design. Transport checks apply to remote servers; scrutiny shifts to §1/§2. |
| PASS | No known vulnerabilities (OSV.dev) | §4.1 | No advisories on record for @undisk-mcp/stdio-proxy @0.54.1 (npm). |
| UNVERIFIABLE | Server-supplied instructions free of poisoning indicators | §5.1–§5.4 | No server-supplied instructions or tool descriptions were obtainable to scan. |
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.
