Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 1 of 21 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 4 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability68
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 412 tokens (~137/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
How do I install the Security MCP server?
Security MCP runs locally as a PyPI package, launched with uvx security-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
audit_site Audit Site ~136
Audits a website's security posture and returns a grade from A+ to F. Checks HTTP security headers (HSTS, CSP, X-Frame-Options and more), the SSL/TLS certificate (valid, issuer, days until expiry), and DNS email-auth records (SPF, DMARC, DKIM). Every finding comes with a plain-English explanation. Use when the user asks how secure a site is, or wants a quick security review of their own website. Takes a domain like "example.com". Defensive audit only: makes normal HTTPS and DNS requests, no scanning or probing beyond that.

| domain | string | yes | – |
| Name | Type | Req | Description |

| result | string | yes | – |
No examples provided.
check_cve Check Cve ~139
Checks whether a vulnerability is actively exploited right now and how likely it is to be exploited soon. Looks the CVE up in CISA's Known Exploited Vulnerabilities catalog (confirmed real-world exploitation, free public feed) and gets its EPSS score from FIRST (probability of exploitation in the next 30 days, free API). No keys or signup needed. Use when the user asks if a CVE is dangerous, being exploited, or worth patching first. Takes a CVE ID like "CVE-2021-44228". Returns a plain-English verdict, never a traceback.
| Name | Type | Req | Description |
|---|---|---|---|
| cve_id | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
lookup_attack Lookup Attack ~137
Explains a cyber attack technique in plain English. Give a MITRE ATT&CK technique ID like "T1566" or a keyword like "phishing", and get back what the technique is, how attackers use it, how to spot it, and how to defend. Data comes from the public MITRE ATT&CK catalog bundled with this server: no API key, no network needed. Use when the user asks how an attack works, what a technique ID means, or how to defend against something. Defensive knowledge only: explains attacks so people can stop them, never how to carry them out.

What tools does the Security MCP server expose?
Security MCP exposes 3 tools: audit_site, check_cve, lookup_attack. Their descriptions and schemas cost roughly 412 tokens of context every time the server is loaded.
Is the Security MCP server still maintained?
Security MCP is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
