MCP Server for OpenProject (Smithery Edition)

This project provides a Model Context Protocol (MCP) server for OpenProject, designed for deployment and use with Smithery. It exposes a set of tools for interacting with a self-hosted OpenProject instance, and is compatible with Smithery's HTTP transport and tool listing requirements.

About this MCP Server

• Built with TypeScript and Node.js using the @modelcontextprotocol/typescript-sdk.
• Exposes OpenProject CRUD tools for projects and tasks (work packages).
• Designed for easy deployment to Smithery, with Docker support and a minimal, production-ready structure.
• Supports local development and testing with MCP Inspector and Smithery tools.

Implemented OpenProject Tools

• Projects:
  • openproject-create-project: Creates a new project.
  • openproject-get-project: Retrieves a specific project by ID.
  • openproject-list-projects: Lists all projects (supports pagination).
  • openproject-update-project: Updates an existing project's details.
  • openproject-delete-project: Deletes a project.
• Tasks (Work Packages):
  • openproject-create-task: Creates a new task within a project.
  • openproject-get-task: Retrieves a specific task by ID.
  • openproject-list-tasks: Lists tasks, optionally filtered by project ID (supports pagination).
  • openproject-update-task: Updates an existing task (requires lockVersion).
  • openproject-delete-task: Deletes a task.

Prerequisites

• Node.js (v18 or later recommended)
• npm
• An OpenProject instance accessible via URL
• An OpenProject API Key
• (Optional) Docker for containerized builds

HTTP Entrypoint and Local Development

This MCP server now uses Express and the official MCP Streamable HTTP transport. The server is accessible at http://localhost:8000/mcp after running npm run dev or npm start.

Entrypoint code (see src/index.ts):

import express from "express";
import { StreamableHTTPServerTransport } from "@modelcontextprotocol/sdk/server/streamableHttp.js";

const app = express();
app.use(express.json());

const mcpServer = setupMCPServer();
const transport = new StreamableHTTPServerTransport({ sessionIdGenerator: undefined });
mcpServer.connect(transport);

app.all("/mcp", (req, res) => {
  transport.handleRequest(req, res, req.body);
});

app.get("/", (_req, res) => res.send("MCP OpenProject server is running!"));

const PORT = process.env.PORT || 8000;
app.listen(PORT, () => {
  console.log(`MCP server running on port ${PORT}`);
});

• The /mcp endpoint is the main MCP HTTP endpoint for Smithery and MCP clients.
• The root / endpoint is a health check.

Running Locally

1. Install dependencies:
   bash

   npm install
   

2. Build the project:
   bash

   npm run build
   

3. Start the server (dev mode):
   bash

   npm run dev
   # or for production
   npm start
   

4. Access the MCP endpoint at http://localhost:8000/mcp

Docker Usage

Build and run as before:

docker build -t mcp-openproject-smithery .
docker run --rm -p 8000:8000 --env-file .env mcp-openproject-smithery

Smithery Deployment

This project is ready for Smithery. The /mcp endpoint is compatible with Smithery's HTTP transport requirements.

Local Testing with MCP Inspector

You can test your MCP server locally using the MCP Inspector:

npx @modelcontextprotocol/inspector npx mcp-remote@next http://localhost:8000/mcp

Open the Inspector URL (usually http://localhost:6274) in your browser to interact with your tools.
