ContrastAPI MCP Server

Remote
v1.35.2
Published by api.contrastcyber.com — no publish provenance and no public repository, so the publisher could not be verified and the source cannot be independently located.
29 security tools for AI agents — CVE, OSINT, threat intel, code security. No API key needed.
The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.
1. Threat score — 100 − 6.3 = 94. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −6.3 | Suspicious external URL in tool metadata MTC-INJ-URL-1 | exfiltration |
2. Client adoption risk — 94 − 3 = 91. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:
| Points | Adoption-risk factor |
|---|---|
| −3 | capability blast radius (moderate) — client exposure if the model is manipulated |
Capability observations and info notes are shown under Findings but never scored.

Findings 3
medium Open-world tool "email_verify" also reads sensitive dataMTC-CAP-004
Tool "email_verify" declares openWorldHint=true — it interacts with entities outside the trust boundary — while also reading sensitive data. That combination is a canonical lethal-trifecta indicator.
Fix: Separate outward-facing tools from sensitive-data reads; require confirmation between them.
Location: tool email_verify
medium Suspicious external URL in tool metadataMTC-INJ-URL-1
A hardcoded link to a request/paste/webhook sink (or raw IP) appears in the inputSchema.properties.url.description of tool "redirect_chain". Tool metadata pointing the model at a fixed external endpoint is a data-exfiltration channel — the classic "send the output to …" poisoning.
Evidence: https://bit.ly/3xyz
Fix: A legitimate tool takes its destination as a validated parameter; it does not hardcode a webhook/paste sink in its description.
Location: tool redirect_chain · inputSchema.properties.url.description
medium Unconstrained URL/host parameter "url" on "redirect_chain"MTC-CAP-007
Tool "redirect_chain" takes a URL/host parameter "url" with no allowlist/pattern. An outbound-request tool with an unbounded destination enables SSRF and cloud-metadata access (e.g. 169.254.169.254).
Fix: Allowlist destinations or constrain the parameter; block private/link-local addresses server-side.
Location: tool redirect_chain · inputSchema.properties.url

Versions 1
Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.
| Version | Score | Findings | Engine | Scanned |
|---|---|---|---|---|
v1.35.2 latest |
A 91/100 | 3 | 1.10.0 | 2026-07-24 |
Embed this score
Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
Verify this score yourself
The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
