Holded + Cursor

Holded — the Spanish SMB business suite: contacts, sales and purchase documents, products, warehouses, treasury accounts and CRM funnels. REST API v1, 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:

HOLDED_API_KEY

Step 1 — Get credentials

Getting a key

  1. Sign in to Holded and open Configuración → Desarrolladores → API key (Settings → Developers).
  2. Generate a key and put it in HOLDED_API_KEY. The key belongs to the account, not to a user, and carries full access to every module you have subscribed to — treat it as a password.

The key travels in a key header. Not Authorization, not a query parameter. Holded's own documentation calls it simply key.

…(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 Cursor

Cursor reads MCP servers from ~/.cursor/mcp.json. Add this entry:

{
  "mcpServers": {
    "anythingmcp": {
      "url": "https://cloud.anythingmcp.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
    }
  }
}
  1. Get your MCP API key from AnythingMCP → Profile → MCP API Keys → New Key.
  2. Save the file and restart Cursor.
  3. Open Cursor → Settings → MCP to verify Holded is listed and "Connected".
  4. Start chatting — all Holded tools are now invokable.
