E Conomic Server

Perfect for anyone who, like me, is more geek than bookkeeper. Finally there is a bit of fun in bookkeeping. Who would have thought.

Getting started

Install dependencies:

npm install

Run the server:

npm start

Environment variables

The server reads e-conomic credentials from the environment:

• ECONOMIC_APP_SECRET_TOKEN (required)
• ECONOMIC_AGREEMENT_GRANT_TOKEN (required)
• ECONOMIC_BASE_URL (optional, defaults to https://restapi.e-conomic.com)
• ECONOMIC_DEBUG (optional, set to true to emit JSON debug logs to stderr)

You'll find all the information on both tokens you need to get started here. It's a bit complex but not as boring and annoying as it looks like by first glimpse. Pinky promise!

Recommended ways to supply tokens

• Local development: keep secrets in .env and run npm start from the repo root so dotenv loads them.
• Desktop MCP clients: either start the server from a shell that has .env loaded, or pass env variables in the client config if you want the client to spawn the server for you.
• CI/shared environments: use your secret manager (GitHub Actions secrets, etc.) and inject env vars at runtime. Do not commit .env.

MCP client setup

Claude Desktop

Add an MCP server entry to your Claude Desktop config file and restart Claude Desktop:

{
  "mcpServers": {
    "e-conomic": {
      "command": "node",
      "args": ["/absolute/path/to/e-conomic-mcp-server/src/server.js"],
      "env": {
        "ECONOMIC_APP_SECRET_TOKEN": "your_token",
        "ECONOMIC_AGREEMENT_GRANT_TOKEN": "your_token",
        "ECONOMIC_BASE_URL": "https://restapi.e-conomic.com"
      }
    }
  }
}

Common config locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\\Claude\\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Claude Code

Add the MCP server via Claude Code:

claude mcp add-json e-conomic '{
  "type": "stdio",
  "command": "node",
  "args": ["/absolute/path/to/e-conomic-mcp-server/src/server.js"],
  "env": {
    "ECONOMIC_APP_SECRET_TOKEN": "...",
    "ECONOMIC_AGREEMENT_GRANT_TOKEN": "...",
    "ECONOMIC_BASE_URL": "https://restapi.e-conomic.com"
  }
}'

Use --scope project to write a shared .mcp.json file in the repo, or --scope user to make it global for your user.

Codex CLI (OpenAI)

Add the MCP server using Codex CLI:

codex mcp add e-conomic --env ECONOMIC_APP_SECRET_TOKEN=... \
  --env ECONOMIC_AGREEMENT_GRANT_TOKEN=... \
  --env ECONOMIC_BASE_URL=https://restapi.e-conomic.com \
  -- node /absolute/path/to/e-conomic-mcp-server/src/server.js

Codex stores MCP configuration in ~/.codex/config.toml if you prefer to edit it directly.

Gemini CLI

Add to your Gemini CLI settings (user or project settings):

{
  "mcpServers": {
    "e-conomic": {
      "command": "node",
      "args": ["/absolute/path/to/e-conomic-mcp-server/src/server.js"],
      "env": {
        "ECONOMIC_APP_SECRET_TOKEN": "your_token",
        "ECONOMIC_AGREEMENT_GRANT_TOKEN": "your_token",
        "ECONOMIC_BASE_URL": "https://restapi.e-conomic.com"
      }
    }
  }
}

Settings files are located at ~/.gemini/settings.json (user) or <project>/.gemini/settings.json (project). System-wide settings live under /etc/gemini-cli/settings.json (Linux), C:\\ProgramData\\gemini-cli\\settings.json (Windows), or /Library/Application Support/GeminiCli/settings.json (macOS).
