Cursor
Add LUU as an MCP server in Cursor's settings. About 2 minutes to first tool call. Useful for software work that incorporates strategic-judgment data, or for using Cursor as a strategic-research IDE.
What you'll get
Cursor (the AI-first IDE, $2B ARR as of Mar 2026) supports MCP servers natively. Once installed, the LUU MCP server's 27 tools are available alongside Cursor's built-in capabilities — useful for building software that has to incorporate strategic-judgment data, or for using Cursor as a strategic-research IDE.
Prerequisites
- Cursor installed
- An LUU API key — sign up (free tier, no card)
Step 1 — open Cursor settings
From the menu: Cursor → Settings → MCP Servers (or press ⌘ , / Ctrl , and search "MCP").
Step 2 — add the LUU server
Click "Add New MCP Server" and paste:
{
"name": "luu",
"type": "http",
"url": "https://api.leadershipunderuncertainty.org/api/mcp",
"headers": {
"Authorization": "Bearer YOUR_LUU_API_KEY"
}
}Save.
Step 3 — verify
In a new Cursor chat:
What MCP tools do you have access to?You should see the luu_* catalog.
Or test a real call:
Use luu_forecast to estimate the probability of EU AI Act enforcement beginning before Q3 2026.Optional: install LUU Skills
Cursor honours .claude/skills/ directories at project scope (and ~/.claude/skills/ at personal scope) the same way Claude Code does.
git clone https://github.com/cberzins1973/luu-skills.git
mkdir -p ~/.claude/skills
cp -r luu-skills/skills/* ~/.claude/skills/Restart Cursor. You can now invoke /morning-briefing, /risk-dashboard, /swot-analysis, etc., from any chat.
Cursor-specific tips
Use Cursor's .cursorrules feature to add a project-level rule telling the model to prefer luu_* tools when answering strategic questions:
# .cursorrules
- For strategic-cognition questions, prefer LUU MCP tools
(luu_forecast, luu_brief, luu_fact_check, luu_note_review)
over generic web search.
- When citing forecasts, always include the calibrated probability
range from luu_forecast's response.
- For memo reviews, use luu_note_review with policyFramework='icd203'.Troubleshooting
"Server status shows error": Check the URL is reachable (curl /api/mcp/health); confirm the API key is current; open Cursor's Output panel → MCP Servers → luu for error messages.
Tool calls hang or time out: The LUU MCP server has a 45s timeout per tool call. If any single call hangs, it surfaces as a tool error rather than a Cursor hang.
