## What it is
r-nacos is a Nacos server re-implemented in Rust, providing service discovery (registry), configuration center, MCP server capabilities, and a web management console. It is fully protocol-compatible with Nacos client SDKs (1.x HTTP OpenAPI and 2.x gRPC), enabling drop-in migration with faster startup, lower resource usage, and higher performance than the Java original.

## Use cases
- replace java nacos in dev/test environments for faster startup
- run a lightweight nacos-compatible registry on small cloud servers
- migrate existing nacos-based microservices without changing client sdks
- expose registered http services as mcp servers for ai agents
- deploy a single-binary or docker config center with low memory footprint
- set up a nacos cluster with docker-compose

## When to choose
- you need nacos protocol compatibility but want lower resource usage and faster startup
- deploying on resource-constrained or small cloud instances without a jdk
- you want built-in mcp conversion of http services

## When to avoid
- you rely on nacos features customized beyond the standard client protocols
- you need the full official nacos ecosystem, plugins, or enterprise support
