MCP Workboard

MCP WorkBoard CrunchTools

A secure MCP (Model Context Protocol) server for WorkBoard OKR and strategy execution platform.

Overview

This MCP server is designed to be:

• Secure by default - Threat modeling, input validation, and token protection
• No third-party services - Runs locally via stdio, your API token never leaves your machine
• Cross-platform - Works on Linux, macOS, and Windows
• Automatically updated - GitHub Actions monitor for CVEs and update dependencies
• Containerized - Available at quay.io/crunchtools/mcp-workboard built on Hummingbird Python base image

Naming Convention

Why Hummingbird?

The container image is built on the Hummingbird Python base image from Project Hummingbird, which provides:

• Minimal CVE exposure - Built with a minimal package set, dramatically reducing attack surface
• Regular updates - Security patches applied promptly
• Optimized for Python - Pre-configured with uv package manager
• Production-ready - Proper signal handling and non-root user defaults

Authorization (3 tools)

• workboard_auth_status_tool - Report auth mode, token store, and whether the credential works (GET /user)
• workboard_auth_start_tool - Return the WorkBoard authorize URL for browser approval (OAuth mode)
• workboard_auth_result_tool - Report the outcome of the most recent authorization redirect

Installation

With uvx (Recommended)

uvx mcp-workboard-crunchtools

With pip

pip install mcp-workboard-crunchtools

With Container

podman run -e WORKBOARD_API_TOKEN=your_token \

quay.io/crunchtools/mcp-workboard

Configuration

Getting a WorkBoard API Token

1. Log in to your WorkBoard instance
2. Navigate to Admin Settings > API Configuration
3. Generate a JWT API token
4. Copy the token immediately - store it securely

Add to Claude Code

claude mcp add mcp-workboard \

--env WORKBOARD_API_TOKEN=your_token_here \ -- uvx mcp-workboard-crunchtools

Or for the container version:

claude mcp add mcp-workboard \

--env WORKBOARD_API_TOKEN=your_token_here \ -- podman run -i --rm -e WORKBOARD_API_TOKEN quay.io/crunchtools/mcp-workboard

OAuth on a Server (Container Behind a Reverse Proxy)

In OAuth mode (WORKBOARD_CLIENT_ID + WORKBOARD_CLIENT_SECRET), a server reachable over HTTPS can be re-authorized without a shell:

1. Register the public callback URL, e.g. https://workboard.example.com/callback, as the redirect URI of the WorkBoard app.
2. Run the server with an HTTP transport and set WORKBOARD_OAUTH_REDIRECT_URI to that same URL. The proxy must route /callback to the server.
3. Call workboard_auth_start_tool, open the URL it returns and approve. WorkBoard redirects to /callback; the server exchanges the code and saves the tokens to the token store. The authorization expires after 10 minutes.
4. Call workboard_auth_status_tool to confirm (or workboard_auth_result_tool to see why it failed).

podman run -p 8000:8000 \

-e WORKBOARD_CLIENT_ID -e WORKBOARD_CLIENT_SECRET \ -e WORKBOARD_OAUTH_REDIRECT_URI=https://workboard.example.com/callback \ -e WORKBOARD_TOKEN_STORE_PATH=/data/tokens.json -v workboard-tokens:/data:Z \ quay.io/crunchtools/mcp-workboard --transport streamable-http --host 0.0.0.0

• Positive integer validation for IDs
• Email validation for user creation

1. API Hardening

• Hardcoded API base URL (prevents SSRF)
• TLS certificate validation
• Request timeouts
• Response size limits

1. Automated CVE Scanning

• GitHub Actions scan dependencies weekly
• Automatic issues for security updates
• Dependabot alerts enabled
