Rainkeeper v0.1.0 — The Raindrop MCP that works on free accounts and actually moves bookmarks

The first public release of Rainkeeper — a self-hostable MCP server for Raindrop.io built on FastMCP.

Why Rainkeeper exists

Two problems with existing Raindrop MCP options:

• The official MCP requires a Pro subscription. Free accounts are locked out.
• The community alternative (adeze/raindrop-mcp) has a silent critical bug: collection moves do nothing. The Raindrop API accepts the malformed request with a 200 OK and silently ignores it. Every move_raindrop call leaves the bookmark exactly where it was.

Rainkeeper fixes both.

What's in v0.1.0

19 tools across five domains:

• Collections (5) — list, get, create, update, delete
• Bookmarks (6) — list, get, create, update, move, delete
• Bulk operations (4) — move, tag, star, delete (batch)
• Search (1) — full Raindrop search syntax supported
• Tags (3) — list, rename, delete

The fix in one line: Rainkeeper sends {"collection": {"$id": 456}}. The community MCP sends {"collectionId": 456}. The API accepts both; only one works.

Validated: 11/11 live tests pass including round-trip move and restore against a real Raindrop account.
