MCP server for cryptographic attestation with 19 tools covering passport issuance, custody chains, cargo validation, and warranties.
Review before connecting
The findings on this server are worth reviewing before you connect an agent to it.
Scanned 1 month ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The hive-mcp-attest MCP server exposes 18 tools, focused primarily on communication capabilities. Its published description reads: "MCP server for cryptographic attestation with 19 tools covering passport issuance, custody chains, cargo validation, and warranties". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates hive-mcp-attest C- — the findings are worth reviewing before you connect an agent to it. Its most notable findings include "Data-exfiltration parameters" and "Cross-tool shadowing". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check hive-mcp-attest's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add hive-mcp-attest to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
Issue a Pre-Action Attestation Manifest (C15: hive-passport). Signs with Ed25519 over RFC 8785 JCS-canonical body. Reference-grade implementation. Wire format normative; production-grade is Layer B.
Verify a Pre-Action Attestation Manifest (C15: hive-passport). Checks Ed25519 signature, temporal validity, and optionally observed inputs hash. Reference-grade implementation. Wire format normative;
Append a node to a custody chain (C16: hive-custody). Taint propagates: once tainted, always tainted. Reference-grade implementation. Wire format normative; production-grade is Layer B.
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
tool: attest_gate_evaluate
A tool exposes a free-text/webhook/feedback parameter with no honest purpose — a classic exfil channel.
parameter "context"RecommendationRemove side-channel parameters; constrain tool inputs.
tool: attest_smsh_verify
A tool description tries to alter the model’s use of another tool.
RecommendationDescriptions must describe only their own tool.
The server accepts tool enumeration (and likely invocation) with no authentication.
