Holded + Claude
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
- Sign in to Holded and open Configuración → Desarrolladores → API key (Settings → Developers).
- 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.
This adapter uses Holded's v1 API (/api/invoicing/v1, /api/crm/v1), which is still served. Holded's current developer site documents a newer v2 API with Authorization: Bearer and different paths; this adapter does not use it.
…(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 Claude
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 showsYOUR_SERVER_ID.
Recommended path — works on claude.ai web without editing any config file.
- In Claude, open Customize → Connectors.
- Click +, then Add custom connector.
- Enter a name, e.g.
Holded, and the remote MCP server URLhttps://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID, then click Add. - Click Connect and sign in to AnythingMCP (OAuth) to allow access.
