NicheDB
Description
Sources in, feeds out: an open, ever-growing database of real-time public data, enriched.
What our measurements say
NicheDB is a remote MCP server published at nichedb.dev. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 1,013 ms, a delay an agent will notice. It exposes a broad tool surface of 17 tools. On the protocol side it speaks the 2026-07-28 stateless spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Most tools have clear, descriptive names that align with their functions.
- Parameters are generally well-defined with types and required/optional flags.
Weaknesses
- Some tool names (e.g., 'stats') are too vague to infer their purpose.
- Descriptions often focus on functionality rather than use cases or triggers.
- Overlapping capabilities between tools (e.g., 'search_items' vs. 'match_items') may confuse agents.
stats— Name does not clearly indicate it provides deployment statistics.list_adapters— Parameter 'config' is an object with no schema details.add_source— Key requirement is mentioned but not explicitly tied to security constraints.

Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round

statsWhat this deployment holds: collections, sources, items, items added today, feeds.
list_collectionsThe collections (niches) with their source, feed and item counts.
list_adaptersEvery adapter this deployment can run, with the config fields each takes. Use before add_source.
list_enrichersEvery enricher (YouTube videos, Wikipedia, repo stats, downloads, company profiles, TL;DRs) and which collections turn it on by default. Items carry their results under `enrichment`.
list_sourcesSources with status, last run and item counts. Optionally one collection.
collectionstring
list_feedsPublic feeds, most followed first. Optionally one collection.

feed_itemsWhat a feed selects, newest first. Page with before_id.

match_itemsWhich title, channel or fixture is this name? Give a file name, a release name or a playlist entry ("Top.Gun.Maverick.2022.1080p.mkv", "US: ESPN2 HD"); it is cleaned (year, season and episode, quality tags, playlist decorations) and matched by similarity. A matchup ("NFL: Chiefs vs Bills", "Lakers @ Celtics", "Rangers at Celtic 19:45") is answered by the fixture whose two teams those are, kicking off between 36 hours ago and 7 days ahead unless date narrows it. Each result carries a score in 0..1. Use screen for films and TV, channels for television channels, sports for fixtures.
