nauro 0.5.1

Local CLI + MCP server: set your project's doctrine once, every connected AI agent inherits it.

Nauro

Set the doctrine once. Every agent inherits it.

Your project's doctrine — goals, decisions, rejected paths — is inherited by every connected agent. When an agent proposes an approach that conflicts with a past decision, Nauro catches the drift before it ships. Works with Claude, Perplexity, ChatGPT, Cursor, and any MCP client.

Install

pipx install nauro   # or: pip install nauro

Requires Python 3.10+.

Quickstart

Watch Nauro catch a conflict in 30 seconds — no account, no MCP wiring, no restart:

mkdir -p /tmp/nauro-demo && cd /tmp/nauro-demo
nauro init --demo
nauro check "Add a WebSocket endpoint for live task updates"

You'll see:

store:    local
project:  demo-project
approach: Add a WebSocket endpoint for live task updates

Related decisions (5):
  004-sse-over-websocket  SSE over WebSocket for live task updates  (score 5.0, status active, decided 2026-03-15)
  002-rest-api-over-graphql  REST API over GraphQL for simplicity  (score 2.4, status active, decided 2026-03-15)
  006-cursor-based-pagination  Cursor-based pagination, not offset  (score 1.3, status active, decided 2026-03-15)
  003-monorepo-with-turborepo  Monorepo with Turborepo over polyrepo  (score 1.0, status active, decided 2026-03-15)
  007-hard-delete-with-audit-log  Hard delete with audit log, no soft deletes  (score 0.5, status active, decided 2026-03-15)

Found 5 related decisions. Top match: D004 "SSE over WebSocket for live task updates" (status active, decided 2026-03-15, BM25 5.0). Call get_decision on each related decision before proposing.

For full rationale, read decision files in ~/.nauro/projects/<project-id>/decisions/, or call the get_decision MCP tool after `nauro setup` + restart.

The demo project ruled out WebSocket because persistent connections weren't released during ECS rolling deploys. Without Nauro, any new agent would happily re-propose it.

For real-project setup (nauro init / nauro adopt), cross-surface access, MCP tool reference, and architecture details, see the main project README. Don't run nauro setup from /tmp/nauro-demo — that would wire the throwaway demo into your MCP client.

Why Nauro?

Memory tools record what agents saw and said. Nauro captures what you decided and rejected, then checks every session against those decisions before they drift.

The check_decision → propose_decision → confirm_decision pipeline surfaces conflicts for you to confirm before they're written, across any connected surface. Decisions made in Claude Code surface in Perplexity. No platform vendor owns your context.

Pricing
