Before You Start

1. Get your API key

Log into Debreu, click your profile icon in the top-right corner to open Account Settings, then go to the API Keys tab and click Generate New Key. Copy the key (it starts with dbr_) — you'll need it in the next steps.

2. Install Node.js (required for most methods)

Download from nodejs.org (version 18 or newer). After installing, open a terminal and verify:

node --version
npm --version

If both print version numbers, you're good to go.

Setup Guide

Claude Code is Anthropic's command-line AI tool that runs in your terminal. This is the fastest way to get started.

1 Install Claude Code

If you don't have Claude Code installed yet, install it via Homebrew or npm:

brew install claude

npm install -g @anthropic-ai/claude-code

The npm method requires Node.js 18+. The Homebrew method does not.

2 Quit Claude Code if it's running

Close any running claude sessions in your terminal. The MCP server won't be picked up until Claude Code restarts.

3 Add the Debreu MCP server

Run this command in your terminal. Replace your_api_key_here with the API key from your Account Settings.

claude mcp add -e DEBREU_API_KEY=your_api_key_here -s user debreu -- npx -y debreu-mcp

4 Start Claude Code

claude

5 Verify it's working

✓Type /mcp in the Claude Code prompt — you should see debreu listed as a connected server
✓Try asking: "What's on my calendar today?" — if it calls a Debreu tool, you're all set

Troubleshooting

"command not found: claude"

Install Claude Code via brew install claude or npm install -g @anthropic-ai/claude-code.

"command not found: npx"

Install Node.js from nodejs.org (version 18 or newer). npx comes bundled with it.

Tools not showing up after adding

Make sure you fully quit and restarted Claude Code. MCP servers only load on startup.

API key errors

Click your profile icon (top-right) → Account Settings → API Keys to verify your key. It should start with dbr_.

New MCP version not loading

Restart Claude Code. npx -y caches the package for the duration of the session.
