MCP Risk

Scan report

ai.waystation/postgres

This page reports an automated security scan of ai.waystation/postgres (remote), scanned 2026-07-28. It rates trust (provenance, transport, known vulnerabilities, instruction integrity) as grade B and capability risk (what the tools can do) separately at unknown. It does not certify the server is safe to connect; it reports what could be checked from outside.

remote, scanned 2026-07-28, tool surface via none

B 85/100 Capability risk: Unknown permalink

The grade rates trust: provenance, transport, known vulnerabilities and instruction integrity. Capability risk rates what the tools can do and is reported, not penalised – a server built to run shell commands is doing its job (Policy §2.4).

  • Security policy (SECURITY.md): absent
INFO Published package is consistent and attested §1.3

No published package associated with this server (remote-only or non-npm/PyPI source).
UNVERIFIABLE Tool surface is inspectable and proportionate §2.1–§2.4

Tool surface could not be inspected (no reachable tools/list, no public package source). Per policy, unverifiability caps the overall grade.
PASS HTTPS-only endpoint §3.1
Endpoint uses HTTPS. 1 finding
  • Endpoint: https://waystation.ai/postgres/mcp
PASS Authentication required §3.2
Server rejects anonymous requests and advertises its auth scheme. 1 finding
  • WWW-Authenticate: Bearer realm="mcp", resource="https://waystation.ai/.well-known/oauth-protected-resource"
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://waystation.ai
INFO No known vulnerabilities (OSV.dev) §4.1

No package to query (remote-only server).
UNVERIFIABLE Server-supplied instructions free of poisoning indicators §5.1–§5.4

No server-supplied instructions or tool descriptions were obtainable to scan.

Verify manually - the scoring model can’t judge these for you

  • §2.3 - Is the tool surface no broader than the server’s stated purpose requires?
  • §3.4 - For stdio servers: which environment credentials does it read, and are they scoped rather than org-wide tokens?
  • §6.1 - Cross this server’s capabilities with your already-connected servers: any read-capability × send-capability pairs need explicit sign-off.
  • §6.2 - Run the connecting agent with sandboxing and egress controls sized to the combined tool surface, not just this server’s.
