+
+## Project Overview
+
+OpenProject MCP Server (`@kollect/openproject-mcp`) — a TypeScript MCP server that bridges AI assistants to OpenProject via the v3 REST API.
+
+## Tech Stack
+
+- **Runtime:** Node.js (ES modules)
+- **Language:** TypeScript (strict, ES2022 target)
+- **MCP SDK:** `@modelcontextprotocol/sdk` (stdio transport)
+- **Validation:** Zod v4
+- **Package manager:** pnpm
+- **Build:** `tsc` → `dist/`
+
+## Project Structure
+
+```
+src/
+  index.ts      — Entry point, server setup, tool registration
+  client.ts     — OpenProject API v3 HTTP client (Basic Auth)
+  tools.ts      — MCP tool definitions with Zod schemas
+  handlers.ts   — Tool handler implementations (API calls + formatting)
+```
+
+## Commands
+
+```bash
+pnpm build          # Compile TypeScript to dist/
+pnpm start          # Run compiled server (requires build first)
+pnpm dev            # Run directly with tsx (no build needed)
+just bootstrap      # Full setup: uv, just, commitizen, pre-commit, git hooks
+just setup          # Install commitizen + pre-commit hooks only
+```
+
+## Environment Variables
+
+- `OPENPROJECT_URL` — Base URL of the OpenProject instance (e.g. `https://openproject.kollect.biz/openproject`)
+- `OPENPROJECT_API_KEY` — API key from OpenProject (My Account > Access Tokens)
+
+## MCP Tools Provided
+
+Projects: `list_projects`, `get_project`
+Work Packages: `list_work_packages`, `get_work_package`, `create_work_package`, `update_work_package`, `add_work_package_comment`
+Relations: `list_relations`, `create_relation`, `delete_relation`
+Lookup: `list_statuses`, `list_types`, `list_priorities`
+Users: `get_me`, `list_users`
+Time: `list_time_entries`, `log_time`
+Versions: `list_versions`
+Activities: `list_work_package_activities`
+
+## Conventions
+
+- Commits follow [Conventional Commits](https://www.conventionalcommits.org/) (enforced by pre-commit hook via commitizen)
+- OpenProject API uses HAL+JSON; link hrefs follow the pattern `/api/v3/<resource>/<id>`
+- Work package updates require `lockVersion` for optimistic concurrency (handled automatically by client)
+- Tool handlers format HAL+JSON responses into human-readable text summaries

+
+## Features
+
+- 18 MCP tools covering projects, work packages, relations, users, time tracking, versions, and activities
+- Stdio transport — works with Claude Code, Zed, Claude Desktop, and any MCP-compatible client
+- HAL+JSON responses formatted into readable text summaries
+- Optimistic concurrency control for work package updates
+
+## Prerequisites
+
+- Node.js 18+
+- pnpm
+- An OpenProject instance with an API key
+
+## Setup
+
+1. **Clone and install:**
+
+   ```bash
+   git clone https://gitea.kollect.biz/KollectRnD/MCP-OpenProject.git
+   cd MCP-OpenProject
+   pnpm install
+   ```
+
+2. **Configure environment:**
+
+   ```bash
+   cp .env.example .env
+   ```
+
+   Edit `.env` with your OpenProject URL and API key:
+
+   ```
+   OPENPROJECT_URL=https://your-instance.openproject.com
+   OPENPROJECT_API_KEY=your-api-key-here
+   ```
+
+3. **Build:**
+
+   ```bash
+   pnpm build
+   ```
+
+## Usage
