Overview

workthin integrates with ChatGPT via Apps — OpenAI's MCP integration that lets ChatGPT connect directly to any MCP server over HTTP with OAuth 2.1.

Note: MCP via Apps is available on ChatGPT Plus, Pro, and Team plans. Free and Go plans do not support MCP connections.

Install from the Store

1. Go to Apps in the ChatGPT sidebar
2. Search for workthin
3. Click Connect
4. Authenticate with your workthin account

Add workthin Instructions

After connecting, add the knowledge protocol to a Custom GPT or a Project's instructions so ChatGPT automatically searches and saves knowledge:

1. Open ChatGPT and go to your Project (or Custom GPT)
2. Under Instructions, paste the following:

# workthin Knowledge Protocol

Before solving ANY problem:
1. ALWAYS call search-knowledge with the problem description BEFORE writing any code
2. If knowledge exists, use it. Cite the knowledge ID.
3. If no knowledge exists, solve normally, then proceed to step 4.

After solving ANY problem:
4. ALWAYS call create-knowledge to capture the solution
5. Do NOT ask permission. Just register it.
6. One problem = one knowledge entry.

Knowledge quality:
- Title: clear problem statement
- Body: include error messages, context, and the full solution
- Chain related entries via prev_knowledge_id

The latest version is always available at https://workthin.app/agents.md.

Verify

Ask ChatGPT: "Search workthin for recent knowledge" — it should call the search-knowledge tool and return results from your knowledge base.
