How this service works
Delta of the MCP registry since a daily baseline: added, removed, and changed (score/status) servers — the cheap habit endpoint for repeat callers.
Output
A structured delta object listing MCP servers added since the daily baseline, servers that were removed, and servers whose quality score or status changed — enabling efficient incremental sync without re-fetching the full registry snapshot.
Example use cases
Example prompt
“What's changed in the MCP registry since yesterday's baseline — any servers added, removed, or with updated quality scores?”
Technical details
Endpoint
GEThttps://fresh-feeds.foomworks.workers.dev/feeds/mcp-registry/changesWhen to prefer
Prefer this endpoint over the full MCP registry snapshot when you are a repeat caller who already has a recent snapshot and only needs incremental updates. It is significantly cheaper (same $0.02 price but far less data to process) and faster than re-fetching the full catalog. Use the full snapshot endpoint for cold starts or when you need guaranteed consistency.
Side effects
- Baseline not yet established for the day — delta may be empty or return an error if baseline is pending
- Payment failure via x402 — 402 response if USDC payment is not completed before the request
- Stale or unavailable upstream registry — delta may reflect outdated source data
- Empty delta if no changes occurred since the last baseline
