topic

topic_scorer_find

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.

topic_scorer_gate

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.

topic_scorer_phrases

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.

topic_scorer_score

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.

topic_scorer_taxonomies

Lists the six taxonomies with their label and category count. Free. Call it first to pick the taxonomy for topic_scorer_find.

Topic Scorer — questions

Answers built from our own checks of this server.

What can Topic Scorer do?

It exposes 5 tools, read directly from the server on our last check. Among them: topic_scorer_find, topic_scorer_gate, topic_scorer_phrases, topic_scorer_score, topic_scorer_taxonomies. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Topic Scorer working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 54 of 92 checks got a reply (58.7%), average response time 263 ms. The bar chart above shows every period we have measured.

Is Topic Scorer still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

The registry lists Topic Scorer as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Topic Scorer?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Topic Scorer need an API key?

No. Topic Scorer completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Topic Scorer?

It answers our handshake in 263 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
