Teamwork MCP Server
Model Context Protocol server for Teamwork.com integration with Large Language
Models

π Are you a Teamwork.com user wanting to connect AI tools (Claude Desktop, VS
Code Copilot Chat, Gemini, etc.) to your Teamwork.com site right now? Jump
straight to the Usage Guide (How to Connect) for tokens,
enabling MCP and client configuration examples.
π Overview
This MCP (Model Context Protocol) server enables seamless integration between
Large Language Models and Teamwork.com. It provides a standardized interface for
LLMs to interact with Teamwork.com projects, allowing AI agents to perform
various project management operations.
π€ What is MCP?
Model Context Protocol (MCP) is an open protocol that standardizes how
applications provide context to LLMs. This server describes all the actions
available in Teamwork.com (tools) in a way that LLMs can understand and execute
through AI agents.
β¨ Features
- Multiple Transport Modes: HTTP and STDIO interfaces for different deployment scenarios
- Secure Authentication: Bearer token and OAuth2 integration with Teamwork.com
- Tool Framework: Extensible toolset architecture for adding new capabilities
- Production Ready: Comprehensive logging, monitoring, and observability
- Read-Only Mode: Optional restriction to read-only operations for safety
π Available Servers
This project provides three different ways to interact with the Teamwork.com MCP
server:
π‘ HTTP Server

π§ͺ Development & Testing
Running Tests
# Run all tests
go test ./...
# Run specific package tests
go test ./internal/twprojects/
MCP Inspector
For debugging purposes, use the MCP Inspector tool:
NODE_EXTRA_CA_CERTS=letsencrypt-stg-root-x1.pem npx @modelcontextprotocol/inspector node build/index.js
[!IMPORTANT]
Note: The NODE_EXTRA_CA_CERTS
environment variable is required when
using OAuth2 authentication with the Let's Encrypt certification authority.
