Install

As a Rust library

[dependencies]
noyalib-mcp = "0.0.51"

Install or run the server through the channel that fits the host:

cargo install noyalib-mcp --locked
npx @sebastienrousseau/noyalib-mcp
docker run --rm -i ghcr.io/sebastienrousseau/noyalib-mcp:latest

Requirements

• Rust 1.88.0 or newer when building from source.
• Linux, macOS, and Windows are tested by CI.
• The crate pins noyalib at exactly =0.0.51 under the lockstep contract.
• An MCP client is required to drive the server.

Quick Start

Use stdio for a child-process integration:

noyalib-mcp

A stdio client begins with an MCP initialization request before sending the initialized notification or listing tools:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "initialize",
  "params": {
    "protocolVersion": "2025-11-25",
    "capabilities": {},
    "clientInfo": {
      "name": "example",
      "version": "0.0.1"
    }
  }
}
