Category Security
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
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-rdap). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 519 tokens (~103/item across 5 items; 5 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 70% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 5 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 0 to 3. That category is still filling its 30-day observation window: 0 days of observed history at the previous scan, 1 at this one. The score rises as the window fills, whether or not the server changes.

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 →
asn ~19
ASN allocation record.
| Name | Type | Req | Description |
|---|---|---|---|
| number | number | yes | – |
No output schema declared.
No examples provided.
domain ~246
Domain registration record from RDAP — registrar, registration/expiry dates, nameservers, status; a "domain not found" answer means the name is UNREGISTERED (available to register, subject to registrar checks). Keyless and authoritative (the registry's own service; the modern replacement for WHOIS). Covers gTLDs and ccTLDs including .io, .me, .de, .us, .ch, .sh and .ac, which IANA's bootstrap file omits. PREFER for "who is the registrar for <domain>", "when does <domain> expire", "who owns <domain>", "WHOIS for <domain>", "is <domain>.com available/registered".
| Name | Type | Req | Description |
|---|---|---|---|
| base | string | – | Optional registry RDAP base URL, e.g. "https://rdap.verisign.com/com/v1". Skips IANA bootstrap lookup — use it when a TLD comes back as tld_not_in_iana_bootstrap and you know the registry endpoint. |
| domain | string | – | Alias for `name`. |
| name | string | – | Domain name, e.g. "openai.com". Also accepted as `domain`. |
No output schema declared.
No examples provided.
entity ~34
Entity by handle. Pass base RDAP url to skip bootstrap.
| Name | Type | Req | Description |
|---|---|---|---|
| base | string | – | – |
| handle | string | yes | – |
No output schema declared.
No examples provided.
ip ~51
IP/netblock allocation record.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | – | IP address, e.g. "8.8.8.8". Also accepted as `ip`. |
| ip | string | – | Alias for `address`. |
No output schema declared.
No examples provided.
nameserver ~117
Nameserver (glue) record from RDAP — the registry's record for a host like "ns1.example.com", with its IP addresses and status. Answers "what are the IPs behind this nameserver" and "is this nameserver registered".
| Name | Type | Req | Description |
|---|---|---|---|
| base | string | – | Optional registry RDAP base URL. Skips IANA bootstrap lookup — use it when a TLD comes back as tld_not_in_iana_bootstrap. |
| host | string | yes | Nameserver hostname, e.g. "ns1.google.com". |
No output schema declared.
No examples provided.
