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 Usability74
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 324 tokens (~162/item across 2 items; 2 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 Management7
- Stability observed for 2 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
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 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.
- 4 Nov 26 +7
- Authorization: fail → partial ▲ security
- Tool “topic_of_document” rewrote its description, which is the text the model reads security
- Tool “topic_of_document” no longer declares itself destructive security
- Schema quality: pass → fail ▼ functional
- Stability: unverified → 0.03 ▲ functional
- “topic_of_document” added an optional parameter “topic_set” cosmetic

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 →
find_topics Find Topics ~187
Tuatara Topics: find the topics in a set of documents. Returns num_topics topics, each with its words, a label, a description and a weight, plus every document's topic mixture, in one call; a dictionary model's word knowledge guides a probabilistic topic model, so topics are coherent on small sets and short texts. Nothing is trained on or kept from the request. 4 to 500 documents of up to 20,000 characters per call.
| Name | Type | Req | Description |
|---|---|---|---|
| documents | array | yes | the documents (plain text), 4 to 500 |
| labels | boolean | – | give each topic a short label and description (default true) |
| num_topics | integer | – | topics to find, 2-100 and at most half the number of documents (default 10) |
| num_words | integer | – | words per topic, 3-30 (default 15) |
No output schema declared.
No examples provided.
topic_of_document Topic Of Document ~137
Tuatara Topics: place one document on the served topic sets — general (Wikipedia-scale) and finance (markets, companies, the economy) — and return the topics it belongs to with their weights, which set placed it, its confidence (the top topic's weight) and on_topic_set (false when nothing served covers the text). Nothing is stored.
| Name | Type | Req | Description |
|---|---|---|---|
| document | string | yes | the document (plain text) |
| num_words | integer | – | words per topic, 3-30 (default 15) |
| topic_set | string | – | auto (default: the set that takes the document most confidently), general or finance |
No output schema declared.
No examples provided.
How do I install the Tuatara Topics MCP server?
Tuatara Topics is a hosted endpoint at https://cymetica.com/mcp/v1/topics, 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.
