feedkit subscribe-catalog -c technology   # subscribe to all 68 tech feeds
feedkit collect                     # fetch all subscriptions (async parallel)
feedkit find "kubernetes"           # full-text search collected articles

Install

pip install feedkit             # core (CLI + Python API)
pip install "feedkit[mcp]"      # + MCP server

feedkit search -c finance -l en -n 50 # combine filters
feedkit search -j                     # JSON output (for piping)

feedkit unsubscribe <URL>

Remove a feed subscription and its collected articles.

feedkit list

List all current subscriptions with fetch counts and error counts.

Collection Commands

feedkit collect

Fetch new articles from all subscribed feeds (async parallel).

feedkit collect                    # collect all
feedkit collect -c technology      # collect only tech feeds
feedkit collect -n 50              # max 50 concurrent requests

feedkit latest                # latest 20 articles
feedkit latest -n 50          # latest 50
feedkit latest -c finance     # latest from finance only

feedkit find <QUERY>

Full-text search (SQLite FTS5) across all collected articles.

feedkit find "kubernetes deployment"
feedkit find "large language model" -n 50

OPML Commands

feedkit import-opml <PATH>

Import feeds from an OPML file (Feedly, Inoreader, NetNewsWire, etc.).

feedkit import-opml subscriptions.opml

feedkit export-opml <PATH>

Python API

from feedkit import search_catalog, fetch_feed, get_catalog_stats, FeedStore
from feedkit.core import collect

# Search the built-in catalog
feeds = search_catalog("cloudflare")
feeds = search_catalog(category="technology", language="en", limit=50)

# Fetch a single feed (async)
entries = await fetch_feed("https://blog.cloudflare.com/rss/")
for entry in entries:
    print(entry.title, entry.url, entry.published)

# Subscribe and collect
store = FeedStore()                              # SQLite at ~/.feedkit/feedkit.db
store.subscribe("https://blog.cloudflare.com/rss/", category="tech")
result = await collect(store, concurrency=20)    # async parallel fetch
print(f"{result.new_articles} new, {result.feeds_ok}/{result.feeds_total} OK")

# Search collected articles (FTS5)
articles = store.search("kubernetes", count=10)

# Latest articles
articles = store.get_latest(count=20, category="tech")

# Feed health
health = store.get_health()                      # fetch/error counts per feed

# Catalog stats
stats = get_catalog_stats()                      # {total_feeds, categories, languages}

store.close()

MCP Workflow Example

User: "What are the latest AI papers on arXiv?"

1. search_feed_catalog(query="arxiv", category="science")
   → finds arXiv cs.AI, cs.LG, cs.CL feeds

2. subscribe_feed(url="https://rss.arxiv.org/rss/cs.AI")

3. collect_feeds(category="science")
   → fetches new entries

4. get_latest_articles(category="science", count=10)
   → returns latest papers

Built-in Catalog

Disclaimer

This package distributes a catalog of publicly available RSS feed URLs, not the feed content itself. RSS is a syndication standard — publishing an RSS feed is an explicit invitation for readers to subscribe. FeedKit fetches feeds on the user's behalf and does not store or redistribute copyrighted content.

Feeds behind hard paywalls (Bloomberg, FT, WSJ, Barron's) and feeds with aggressive terms of service have been removed from the catalog.
