How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security11
- TLS not yet verified: we couldn't open a connection to check the certificate. View diagnostics → Unverified
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS not yet verified: we couldn't read the response headers to check for it. View diagnostics → Unverified
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but we couldn't connect to verify it. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the VulnHunt Security Intelligence MCP server?
VulnHunt Security Intelligence is a hosted endpoint at https://vulnhunt-agent-api-production.up.railway.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the VulnHunt Security Intelligence MCP server?
VulnHunt Security Intelligence is an MCP server listed in the public MCP registry as io.github.owenkingva-web/vulnhunt. Read-only smart-contract security intelligence for autonomous agents. This page covers its hosted endpoint (https://vulnhunt-agent-api-production.up.railway.app/mcp).
Is the VulnHunt Security Intelligence MCP server safe to use?
VulnHunt Security Intelligence scores 23 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the VulnHunt Security Intelligence MCP server expose?
VulnHunt Security Intelligence exposes 11 tools: vulnhunt_decision, vulnhunt_payment_resources, vulnhunt_chains, gpufeed_get_cheapest, gpufeed_get_availability, and 6 more. Their descriptions and schemas cost roughly 382 tokens of context every time the server is loaded.
Does the VulnHunt Security Intelligence MCP server require authentication?
Its publisher declares no required credentials for VulnHunt Security Intelligence. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the VulnHunt Security Intelligence MCP server still maintained?
VulnHunt Security Intelligence is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
