One catalog, several read surfaces

Stop maintaining a copied startup-credit list.

Sourcey publishes the same current catalog as visible HTML, complete JSON, a signed change feed, API reads, and read-only MCP tools. The current release is sha256:317c176df9f8cd008f26da88282e24d18b829897c93f4ddae8940151c4944c19. Facts are licensed under CC BY 4.0.

The complete snapshot carries its release identity. The change feed uses signed cursors for incremental reads. Consumers must store the last accepted cursor and release ID, reject an invalid cursor, and take a fresh canonical snapshot when the retained feed window no longer covers their checkpoint.

Use it from an agent

Connect https://mcp.sourcey.com/mcp and read its exact generated tool contract with tools/list. See the MCP guide or hosted manifest; this page does not maintain a second tool list.

Migrate a copied list

  1. Take one complete snapshot from /catalog.json.
  2. Store its exact release ID and the records your product uses.
  3. Replace hand-edited rows with projections keyed by immutable Entity, Program, and Offer IDs.
  4. Consume /changes.ndjson from the saved cursor.
  5. Link each displayed fact to its canonical Sourcey record and revision.
  6. Re-read the full snapshot when the feed reports that the cursor is outside retention.

Integration problems go to support. Catalog corrections use the public contribution and claim paths listed there. A recurring consumer is counted only after a second identifiable update read; a one-time download is not adoption.
