MCP (Model Context Protocol) server for [Hudu](https://www.huduapp.com/) IT documentation platform. Provides 39 tools and 6 resources for managing companies, assets, articles, passwords, websites, and more through any MCP-compatible client.

## Features

- **39 MCP tools** covering all major Hudu resources
- **6 MCP resources** for direct data access
- **Dual transport** support: stdio (default) and HTTP Streamable
- **Lazy initialization** - SDK client created on first tool call
- **Connection testing** built-in
- **All logging to stderr** to avoid polluting MCP stdio transport

## One-Click Deployment

> [!IMPORTANT]
> **Before you click:** this server depends on `@wyre-technology/node-hudu`,
> which is hosted on the **GitHub Packages** npm registry. GitHub Packages has no
> anonymous access — even though the package is public, every `npm install` needs a
> token. The cloud builder runs `npm install` for you, so you must give it one, or
> the build fails with `npm error 401 Unauthorized ... npm.pkg.github.com`.
>
> 1. Create a GitHub **Personal Access Token** with the `read:packages` scope
>    ([classic token](https://github.com/settings/tokens/new?scopes=read:packages&description=hudu-mcp%20deploy)).
>    Any GitHub account works — you do **not** need to be a member of the
>    `wyre-technology` org to read its public packages.
> 2. Add it as a build variable when prompted by the deploy flow:
>    - **DigitalOcean App Platform** → set an encrypted env var named **`NODE_AUTH_TOKEN`**
>      with scope **Build Time** to your PAT (the `Dockerfile` reads it via
>      `ARG NODE_AUTH_TOKEN` to authenticate `npm ci`).
>    - **Cloudflare Workers** → set a build variable named **`NODE_AUTH_TOKEN`** to your PAT
>      (Workers → Settings → Build → Variables and Secrets).

[![Deploy to Cloudflare Workers](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/WYRE-AI/hudu-mcp)

> [!NOTE]
> The DigitalOcean target builds the full Docker image and runs the complete MCP
> server over HTTP — this is the recommended path for operators. This repo does not
> ship a `wrangler.json`/Workers entrypoint, so for a self-hosted server prefer
> DigitalOcean or the prebuilt container image (`ghcr.io/wyre-ai/hudu-mcp`).

## Installation

This project depends on `@wyre-technology/node-hudu`, published to the **GitHub
Packages** npm registry, which requires a token even for public packages.
Authenticate npm once before installing:

```bash
git clone https://github.com/WYRE-AI/hudu-mcp.git
cd hudu-mcp

# Authenticate npm to GitHub Packages (token needs the read:packages scope)
export NODE_AUTH_TOKEN=$(gh auth token)   # or a PAT with read:packages

npm install
npm run build
```

The repo's `.npmrc` already points the `@wyre-technology` scope at GitHub Packages and
reads the token from `NODE_AUTH_TOKEN`, so no further config is needed.
