Combine the remote MCP server (stdio + remote /mcp + OAuth 2.1 + read tools + deep-value reads + a confirmed, audience-bound write surface) with the v1.23 account-security line (MFA, known/trusted devices, free-text note encryption). - schema: keep every v1.23 User relation (MFA, known/trusted devices) alongside the McpOAuthConnection relation; the MeasurementSource enum carries the MCP value. - api-handler: the MCP audience guard (a token scoped to health:read/health:write is bound to /mcp and refused a REST write) and the step-up MFA helpers coexist. - maintenance queues: register the MCP token-cleanup sweep next to the note-encryption backfill and key-rotation queues; shift it to 04:00 so the two daily discovery ticks do not collide. - migrations: renumber the MCP migrations to 0206/0207 so they follow the v1.23 chain (0199-0205). - MCP mood writes route the note through the v1.23 at-rest cipher.
prisma/
The database layer. HealthLog runs PostgreSQL 16 via Prisma 7. This directory holds the single schema file and the forward-only migration history; the generated client is emitted elsewhere.
Contents
schema.prisma— 61 models, one file.cuid()primary keys,snake_casecolumns via@map(...), encrypted columns mostly suffixed*Encrypted(search the file; there are 24 encrypted column references). Thegenerator clientblock emits to../src/generated/prisma(imported as@/generated/prisma).migrations/— numbered, forward-only SQL migrations (0001_…upward).migration_lock.tomlpins the provider topostgresql.
Migration workflow
# author a migration from a schema edit
pnpm dlx prisma migrate dev --name <short_snake_case_name>
# regenerate the client after any schema change
pnpm dlx prisma generate
Number a new migration with the next free prefix. The production entrypoint runs prisma migrate deploy on boot, so every migration must apply cleanly forward — there is no down-migration path. Always include the migration file in the same change as the schema edit.
Conventions
- Encryption is fail-closed:
*Encryptedcolumns are written through@/lib/crypto(AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation isscripts/rotate-encryption-key.ts+docs/ops/encryption-key-rotation.md. - The generated client under
src/generated/prismais build output — do not edit it. - Schema-touching changes that affect the API surface must regenerate
docs/api/openapi.yaml(see../CLAUDE.md).
