Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "openproject": {
      "command": "npx",
      "args": [
        "-y",
        "openproject-codex-plugin"
      ],

        "OPENPROJECT_URL": "your-value",
        "OPENPROJECT_API_TOKEN": "your-value",
        "OPENPROJECT_PAGE_SIZE": "your-value",
        "OPENPROJECT_TIMEOUT_MS": "your-value",
        "OPENPROJECT_AUTH_MODE": "your-value",
        "OPENPROJECT_ALLOWED_UPLOAD_DIRS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add openproject --env OPENPROJECT_URL=your-value --env OPENPROJECT_API_TOKEN=your-value --env OPENPROJECT_PAGE_SIZE=your-value --env OPENPROJECT_TIMEOUT_MS=your-value --env OPENPROJECT_AUTH_MODE=your-value --env OPENPROJECT_ALLOWED_UPLOAD_DIRS=your-value -- npx -y openproject-codex-plugin

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "openproject": {
      "command": "npx",
      "args": [
        "-y",
        "openproject-codex-plugin"
      ],
      "env": {

        "OPENPROJECT_API_TOKEN": "your-value",
        "OPENPROJECT_PAGE_SIZE": "your-value",
        "OPENPROJECT_TIMEOUT_MS": "your-value",
        "OPENPROJECT_AUTH_MODE": "your-value",
        "OPENPROJECT_ALLOWED_UPLOAD_DIRS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "openproject": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "openproject-codex-plugin"

        "OPENPROJECT_ALLOWED_UPLOAD_DIRS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is OpenProject safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: OPENPROJECT_URL, OPENPROJECT_API_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

OpenProject MCP server

A comprehensive, write-capable Model Context Protocol server for OpenProject API v3. Its 41 focused tools cover projects, work packages, attachments, relations, boards, users, watchers, notifications, and reference data.

Attachment tools can list files on a work package and fetch their content. Text-based files are returned directly; binary files are returned as embedded MCP resources. Uploads and downloads are size-limited per request.

The package is maintained as part of OpenProject for Codex, which also includes Codex workflow guidance and portable installers.

Run with an MCP client

Configure these environment variables:

OPENPROJECT_URL: the root URL of your OpenProject instance;
OPENPROJECT_API_TOKEN: an API token with only the permissions you need.

OPENPROJECT_BASE_URL and OPENPROJECT_API_KEY are accepted as compatibility aliases for existing MCP configurations.

Optional settings:

OPENPROJECT_PAGE_SIZE: default collection page size from 1 to 100 (default 25);
OPENPROJECT_TIMEOUT_MS: request timeout from 1000 to 300000 milliseconds (default 30000);
OPENPROJECT_AUTH_MODE: basic for broad compatibility (default), or bearer for OpenProject 17.2 and newer.
OPENPROJECT_ALLOWED_UPLOAD_DIRS: platform-separated directories from which upload tools may read files (default: current working directory).

Then launch the stdio server with:

npx -y openproject-codex-plugin

Example MCP configuration:

"mcpServers": { "openproject": { "command": "npx", "args": ["-y", "openproject-codex-plugin"], "env": { "OPENPROJECT_URL": "https://tasks.example.com", "OPENPROJECT_API_TOKEN": "your-api-token" } } } }

Never commit API tokens or include them in public logs and screenshots.

Capabilities

Project CRUD, counts, native filters, sorting, and pagination.
Work-package search, CRUD, comments, activity history, scheduling, estimates, progress, hierarchy, assignees, responsible users, priorities, statuses, and versions.
Attachment listing, authenticated reads, local-file uploads, and deletion.
Relations and watcher management.
Current-user lookup, user search, and permission-aware available assignees.
In-app notifications and Kanban-style board inspection.
Status, priority, type, and version discovery.
Restricted GET-only passthrough for uncovered paths under /api/v3.

Read, write, and destructive tools carry MCP annotations so compatible clients can apply appropriate confirmation policies. Collection responses include total, count, offset, pageSize, and hasMore metadata.
