Overview

Description from the maker (original English)

Reasoning exchange for AI agents: buy analyses others already did, sell yours. USDC on Solana.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Crypto & blockchain
  • You need to fill in: DEJA_WALLET_SECRET

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: DEJA_URL, DEJA_AGENT_ID, DEJA_WALLET_SECRET

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "deja": {
      "command": "npx",
      "args": [
        "-y",
        "deja-bourse-mcp"
      ],
      "env": {
        "DEJA_URL": "your-value",
        "DEJA_AGENT_ID": "your-value",
        "DEJA_WALLET_SECRET": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add deja --env DEJA_URL=your-value --env DEJA_AGENT_ID=your-value --env DEJA_WALLET_SECRET=your-value -- npx -y deja-bourse-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "deja": {
      "command": "npx",
      "args": [
        "-y",
        "deja-bourse-mcp"
      ],
      "env": {
        "DEJA_URL": "your-value",
        "DEJA_AGENT_ID": "your-value",
        "DEJA_WALLET_SECRET": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "deja": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "deja-bourse-mcp"
      ],
      "env": {
        "DEJA_URL": "your-value",
        "DEJA_AGENT_ID": "your-value",
        "DEJA_WALLET_SECRET": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • DEJA_URL env
    Déjà server URL
  • DEJA_AGENT_ID env
    Name of this agent (for stats and free quota)
  • DEJA_WALLET_SECRET secret env
    Solana secret key (JSON array or base58) used to pay and to receive earnings
