Available components
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 →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 409 tokens (~136/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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.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: 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.
get_ai_crawler_policy Get AI crawler policy ~110
Which of the eight tracked AI crawlers a domain's robots.txt admits, and whether it publishes an llms.txt. Three states per agent: allowed, disallowed, unspecified. Unspecified is NOT allowed, because a catch-all Disallow blocks an agent the file never names, so read `effective` for what is in force. Reads the last stored reading; it does not fetch the file.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | A domain name. Scheme, www and trailing dots are stripped. |
No output schema declared.
No examples provided.
list_sources List data sources ~59
What Domduck reads and what each source means, including the eight AI crawlers whose robots.txt policy is tracked. A constant. Read it first: it is what lets a model interpret lookup_domain without guessing at field names or at which direction is better.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
lookup_domain Look up one domain ~105
Public reputation snapshot for one domain from Domduck's store: Domain Rating, Tranco rank, OpenPageRank, registration date, TLS certificate state and AI crawler policy. Returns hasReading false for a domain nobody has looked up yet, which is a real answer and not an error. One domain per call, and no history: the dated series is what a Domduck account is for.
| Name | Type | Req | Description |
