Axonaut + Gemini

Axonaut — French all-in-one CRM, invoicing and expense management for very small businesses: companies, employees, invoices, quotations, expenses, products and projects. REST API v2, API-key auth.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

AXONAUT_API_KEY

Step 1 — Get credentials

Getting a key

  1. Sign in to Axonaut and open Paramètres → API (Settings → API).
  2. Copy the key into AXONAUT_API_KEY. It is account-wide and carries full access; treat it as a password.

The header is userApiKey. Not Authorization, not X-API-Key — Axonaut's own spelling, camel-cased, is what the server checks.

Axonaut calls customers 'companies' and people 'employees'. A company is a client or prospect organisation; an employee is a person attached to one. This trips people up, because 'employee' sounds like your own staff and is not.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Gemini

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}
  1. Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
  2. Save the file and restart gemini.
  3. Run /mcp inside the Gemini CLI — Axonaut should be listed as available.
  4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID to the tools array of your request with the same X-API-Key header.
