MateCloud is a Java-based platform for building multi-tenant business applications from cooperating services, using Spring Cloud Alibaba and domain-driven design. It supports SaaS and low-code development with built-in services for authentication, administration, notifications, messaging, and AI features. The catalogue add-ons operate MateCloud through its command-line and MCP-based tooling.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02264 | $0.02264 |
| Opus 5.5 | $0.00906 | $0.00906 |
| Sonnet 5.5 | $0.00453 | $0.00453 |
| Haiku 4.5 | $0.00226 | $0.00226 |
Grade A, and why
matecloud CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to matecloud AGENTS.md — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Project Overview
MateCloud is a DDD microservice scaffold built with Spring Boot 4.0.7 + Spring Cloud 2025.1.2 + Spring Cloud Alibaba + Dubbo 3.3.6. Java 21, MyBatis Plus, Sa-Token auth, Redisson, MapStruct.
Philosophy: minimal common, each module does one thing well, starter = plug-and-play capability.
Development Commands
Backend (Java / Maven)
# Full build (42 modules)
mvn clean install -DskipTests
# Build one module with dependencies
mvn clean install -pl mate-biz/mate-system -am -DskipTests
# Run a service (requires infra: Nacos + MySQL + Redis)
make infra-up # start MySQL/Redis/RabbitMQ/Nacos/MinIO
cd mate-biz/mate-system && mvn spring-boot:run
# Tests
mvn test # unit tests
mvn verify -Pintegration-test # integration (Testcontainers)
# Generate API docs (Smart-Doc, not Swagger)
mvn smart-doc:html -pl mate-biz/mate-system
# Database migration
java -jar mate-cli/target/mate-cli.jar db migrate --module mate-system
Frontend (mate-ui)
cd mate-ui
pnpm install # pnpm monorepo (turbo orchestration)
pnpm dev # Vite dev server → http://localhost:3000
# Default dev credentials (created by AdminUserSeeder on first boot):
# admin / admin123 / 13800138000
Frontend is a pnpm workspace monorepo: apps/admin (Vue 3 + Vite + Element Plus + TypeScript) with shared packages in packages/{core,hooks,ui,utils}. Vite proxies /api to http://127.0.0.1:9010 (gateway).
Docker / Compose
IMPORTANT — only
docker-compose(v1, hyphenated) is supported in this environment. NEVER usedocker compose(v2, space). All compose commands must use thedocker-compose ...binary, run from the repo root.
docker-compose build mate-system mate-ui # rebuild changed images
docker-compose up -d mate-system mate-ui # recreate (Flyway auto-runs new migrations on mate-system boot)
docker-compose logs -f mate-system # watch logs
# Upgrade flow: git pull → docker-compose build <svc> → docker-compose up -d <svc>. Never `down -v` (wipes volumes).
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
