Standardize on idempotent write endpoints

Agent Memory Database across · shared project memory — local-first · offline-ready
Memory needs relations and vectors. PostgreSQL gives both. Types, versions, sequences, tenant isolation — queryable with psql, BI, notebooks. No proprietary export.
Semantic recall without lock-in: local Ollama or remote provider, or pure FTS. Corpus stays in your PostgreSQL, queryable forever. Start free, no external API.

BRIEFING FOR NEW SESSION
Source: architecture.md
Source: pull request #214
Source: auth/session.ts
WHY IT MATTERS HERE
Across Peru, software teams ship faster when their tools share one memory instead of three silos. Distributed squads stay aligned because every session opens with the same briefing.
Teams operating under Law 29733 can point at a concrete architecture instead of promises.
UNIVERSAL COMPATIBILITY
If it speaks MCP or reads a JSON config, MemHub plugs in. One command wires the majors; everything else joins as a generic client.
WHAT YOU GET
Replicas, backups, PITR — reuse the PostgreSQL playbook your team already runs.
Versioned SQL migrations with checksums — not a migration essay.
BI, notebooks, audits over standard SQL — no proprietary export tax.
One PostgreSQL for memory, sync cursors, audit, billing — boring, battle-tested, browsable with psql.
pgvector HNSW indexes included — enable embeddings locally via Ollama, or stay FTS.
Row-level policies — a bug in one project’s code can’t read another org’s rows.
No feature-matrix gymnastics — just what changes the week you adopt MemHub.
| Without MemHub | With MemHub |
|---|---|
| Context lives in heads and DMs → onboarding takes days | Structured, searchable memory → new dev/agent productive in minutes |
| Every agent re-learns the repo from scratch | Sessions open pre-briefed with only what changed — zero re-explaining |
| Rules files cap out at ~2k tokens | Unbounded versioned history stays one query away — never cap again |
| Decisions re-litigated, bugs re-introduced | Pinned invariants prevent regressions — agents respect past calls |
One command for Claude Code, Cursor, Codex, Windsurf, Cline or any MCP client. No new editor. Setup in 2 minutes, works offline.
$ npm install --global @simplexlat/memhub

✓ project resolved · context ready · memory synchronized
Yes — any Postgres 16 with pgvector works, including Easypanel, RDS, Cloud SQL, or Neon; self-hosted and hosted modes share identical schemas.
Memory needs relations (tenants, projects, authors, versions) as much as vectors. PostgreSQL provides both, plus the operational maturity no niche store matches.
Nothing interrupts the work. Writes commit to the local SQLite outbox and synchronize automatically when the shared service is reachable again.
Yes — the local engine works fully offline, and the self-hosted stack keeps even the shared layer on your own PostgreSQL.
A Community tier is free, and the Team plan adds multi-project contexts, seats, and higher synchronization limits. Self-hosting is unlimited.
