No required environment variable is listed on this record.

What transport does Pluribus use?

Pluribus runs locally over stdio.

Documentation

Out of many agents, one memory.

Pluribus

Pluribus is the open control plane for governed AI memory: Postgres-backed durable rows, situation-shaped recall, pre-change enforcement, and curation — without treating chat or logs as source of truth.

Usage: recall_context → plan → act → record_experience. Skip the loop and you get amnesia.

Start here: docs/get-started.md (run → connect → optional doctrine).

What this is

Piece	Location
Runnable API	`pluribus` service on `:8123` (`docker compose up -d`)
Go implementation	`control-plane/` module
Agent packs	`integrations/` + `pluribus-instructions.md`
Canonical model	`docs/memory-doctrine.md`
Full doc index	`docs/README.md`

Quick start

docker compose up -d
make smoke-shared-memory

Add MCP at http://127.0.0.1:8123/v1/mcp and paste integrations/pluribus-instructions.md into your editor rules. Details: get-started · MCP usage · Cursor pack.

The memory database is sacred — in-place upgrades only; see operate/guide.

Why use it

Benefit	What it avoids
Continuity	Re-deriving constraints and failures every session
Shared truth	Memory trapped in one chat or editor
Authority-aware recall	Flattening everything into one similarity score
Enforcement	Shipping changes that violate stated decisions
Curated learning	Promoting noise without review

Repository layout

Path	Purpose
`control-plane/`	Go API (`make build` → `./pluribus`)
`integrations/`	Per-editor MCP + rules packs
`docs/`	Public documentation (index)
`scripts/`	Upgrade, backup, proof, verification
`evidence/`	Proof artifacts

Internal maintainer notes: docs/meta/ (not product truth).

Verification

make regression          # CI gate
make smoke-shared-memory # quick shared-memory check
