Course tools

An MCP server your AI app can use while your team works on a company research project. It serves a public guide and asks questions. It keeps nothing you send.

The tools

• start: asks what you are trying to decide this week, shows the chain and where you might be on it, and three ways in.
• read: one section of the guide, word for word.
• this_week: what to think about at your stage, and one example next step.
• check_hypothesis: one checking question per slot of your hypothesis, and which slot to take to an interview first. It never rewrites your hypothesis.

Where your app shows prompts, there are two: plan-next-step and challenge-hypothesis.

Connect your AI app

Server address: https://a4b.linxule.com/mcp

• Claude: Settings → Connectors → Add custom connector, then paste the address. The free plan allows one custom connector, and the chain view renders.
• ChatGPT: needs Developer mode, on the web, with Plus, Pro, Business, Enterprise or Edu. Free accounts cannot add custom connectors.
• Mistral Le Chat: add it as a custom connector. Tools only.
• Codex CLI or IDE (works on the free plan): codex mcp add a4b --url https://a4b.linxule.com/mcp
• Gemini: custom connectors are US-only, so it will not connect from elsewhere.

The guide

The student guide, as plain text. Give it to your AI at the start of a new chat, together with your team note.

Keep interview notes, names and non-public company information out of AI tools, this one included.
