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 → Why this is hard to 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 Usability78
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 572 tokens (~143/item across 4 items; 4 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 Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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
How do I install the Xither — AI vendor record MCP server?
Xither — AI vendor record is a hosted endpoint at https://www.xither.com/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.

No change was recorded against any check on this day. Stability & Change Management went from 13 to 20. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 6 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 →
lookup_vendor Look up one vendor's record ~158
The Xither record for one vendor: where it publishes its sub-processor list and data processing agreement and when Xither last read each page (or why a page cannot be read), the notice window its agreement states for new sub-processors (quoted, with source URL and read date), its public changes to either document with permalinks, and model retirement dates it publishes for the next 365 days. One vendor per call; accepts a name, slug or domain. Changes appear 30 days after Xither records them; subscribers get them the same morning at www.xither.com/pricing.
| Name | Type | Req | Description |
|---|---|---|---|
| vendor | string | yes | A vendor name, slug or domain, for example "HubSpot", "hubspot" or "hubspot.com". |
No output schema declared.
No examples provided.
notice_windows Sub-processor notice windows ~127
Every sub-processor notice window Xither can quote: the number of days (business days where the clause says so) each vendor's own terms state for a new sub-processor, and what that number counts (basis: 'objection' = time to object once told, 'notice' = notice before the change, 'unstated' = the clause does not settle it), with the verbatim clause, its source URL and the date Xither read it. The same table as www.xither.com/notice-windows. A vendor not listed has no window Xither could quote.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_vendors Find vendors by name ~73
Find vendors in the Xither record by name, slug or domain. Returns up to 10 matches, each with its name, slug and record URL, and no record data. Pass a slug to lookup_vendor for the record.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Part of a vendor name, a slug or a domain. |
No output schema declared.
No examples provided.
upcoming_model_retirements Upcoming model retirements ~118
Model and API retirement dates from the retirement tables vendors publish, as Xither last read them, soonest first: model, date, the replacement the vendor names, the verbatim table row, source URL and read date. Optional vendor filter; within_days defaults to 90, maximum 365; at most 50 rows. Covers only vendors whose retirement tables Xither reads.
| Name | Type | Req | Description |
|---|---|---|---|
| vendor | string | – | Optional vendor name, slug or domain. |
| within_days | integer | – | How many days ahead to look, from today. |
No output schema declared.
No examples provided.
