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 Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 826 tokens (~165/item across 5 items; 5 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 94% 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

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 →
topic_scorer_find Find Categories ~89
Finds categories whose path contains the query (case-insensitive substring), optionally within one taxonomy. Free. Returns up to `limit` hits with id and path; pass the id as `category` to the scoring tools.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| query | string | yes | Words to look for in category paths. |
| taxonomy | string | – | Taxonomy of the target category. |
No output schema declared.
No examples provided.
topic_scorer_gate Gate Text ~226
Pass/fail check: does the text rank within the top `min_rank` categories of its target taxonomy? Returns `pass`, the target's rank and gap to #1, the taxonomy's top five, and the unused phrases to work in. Use it as a content-pipeline gate. Free; read-only and safe to retry.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | yes | Target category id, full path, or a unique path substring within the taxonomy (use topic_scorer_find to look one up). |
| full | boolean | – | Score the whole text as the mean of 8,192-char chunks instead of only the first 8,192 chars. |
| min_rank | integer | – | Highest passing rank. |
| phrases | integer | – | Phrase bank size for the target category (0 skips it). |
| taxonomy | string | yes | Taxonomy of the target category. |
| text | string | yes | The page or draft text to score, as plain text or HTML (tags are stripped). 1 to 32768 characters. URLs are not fetched; send the content. |
No output schema declared.
No examples provided.
topic_scorer_phrases Phrase Bank ~117
Returns the ranked phrase bank for one category: 1 to 4 word phrases a page squarely about that category would contain, ordered by similarity to the category. Use it to seed a brief. Free; read-only and safe to retry.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | yes | Target category id, full path, or a unique path substring within the taxonomy (use topic_scorer_find to look one up). |
| n | integer | – | Bank size. |
| taxonomy | string | yes | Taxonomy of the target category. |
No output schema declared.
No examples provided.
topic_scorer_score Score Text ~257
Scores text against every category in all six taxonomies (one embedding, cosine similarity) and returns the top `per` rows per taxonomy. With `taxonomy` and `category` it also returns the target's rank, score, gap to #1, and a phrase bank split into phrases the text already uses and phrases it does not. Read the rank and the gap, not the raw percent (scores compress into a 70 to 90 band). Free; read-only and safe to retry.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Target category id, full path, or a unique path substring within the taxonomy (use topic_scorer_find to look one up). |
| full | boolean | – | Score the whole text as the mean of 8,192-char chunks instead of only the first 8,192 chars. |
| per | integer | – | Rows per taxonomy. |
| phrases | integer | – | Phrase bank size for the target category (0 skips it). |
| taxonomy | string | – | Taxonomy of the target category. |
| text | string | yes | The page or draft text to score, as plain text or HTML (tags are stripped). 1 to 32768 characters. URLs are not fetched; send the content. |
No output schema declared.
No examples provided.
topic_scorer_taxonomies List Taxonomies ~40
Lists the six taxonomies with their label and category count. Free. Call it first to pick the taxonomy for topic_scorer_find.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
How do I install the co.pixelcove/topic-scorer MCP server?
