Mind Cloud Lite Changelog

v1.1.0 (2025-03-23)

Critical Fixes

  • Fix MCP connection failures — Added notification handling (notifications/initialized). Without this, every connection attempt failed after the handshake.

Security Fixes

  • Auth moved to environment variables — MIND_API_KEY is now set via npx wrangler secret put MIND_API_KEY instead of hardcoded in source code. Supports both secret path and Bearer token auth.
  • Timing-safe auth comparison — Auth checks now use constant-time comparison to prevent timing attacks.
  • Basic auth support — Added Basic auth in addition to Bearer token auth.
  • /process endpoint now requires auth — Previously accessible without authentication.
  • Error responses no longer leak internals — Tool errors return a generic message instead of exposing stack traces and database details.

Data Integrity

  • Identity writes now upsert — Writing to the same identity section updates it instead of creating duplicates. Requires migration 0004_identity_unique.sql.
  • mind_identity schema fix — Added required: ["action"] to prevent calls without specifying read/write.

Migrations

  • 0004_identity_unique.sql — Adds UNIQUE constraint to identity.section, deduplicates existing entries.

Upgrading from v1.0.0

  1. Run the new migration: npx wrangler d1 execute mind-lite --remote --file=migrations/0004_identity_unique.sql
  2. Set your API key as a secret: npx wrangler secret put MIND_API_KEY
  3. Redeploy: npx wrangler deploy
