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 - Comprehensive 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

Security

This server was designed with security as a primary concern. See SECURITY.md for:

• Threat model and attack vectors
• Defense in depth architecture
• Token handling best practices
• Input validation rules

Key Security Features

1. Token Protection

• Stored as SecretStr (never accidentally logged)
• Environment variable only (never in files or args)
• Sanitized from all error messages

1. Input Validation

• Pydantic models for all inputs
• 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
