Holded + Microsoft Copilot

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.

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 Microsoft Copilot

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.

Microsoft Copilot uses MCP servers through agents built in Copilot Studio: you add AnythingMCP to an agent as a tool, then publish the agent to Microsoft 365 Copilot and Teams. Copilot Studio connects from Microsoft's cloud over Streamable HTTP, which AnythingMCP supports.

  1. In Copilot Studio, open your agent (or create one), go to Tools and choose Add a tool → New tool → Model Context Protocol.
  2. Enter a Server name (for example AnythingMCP), a Server description that says what the connector does, and the Server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID. Copilot Studio uses the description to decide when to call the server.
  3. Under authentication, choose API key, set Type to Header and the header name to X-API-Key, then select Create.
  4. In Add tool, choose Create a new connection, paste an MCP API key from AnythingMCP (MCP Servers → your server → API keys) and select Add to agent.
  5. Try it in the agent's Test pane: ask for something that needs the Holded tools.
  6. Select Publish, then Channels → Microsoft 365 and Microsoft Teams, keep Make agent available in Microsoft Copilot selected and choose Add channel. See agent in Teams installs it for you; in Microsoft 365 Copilot, type @ and pick the agent.

Prefer per-user sign-in? Choose OAuth 2.0 → Dynamic discovery instead of an API key: each user then signs in to AnythingMCP the first time the agent calls it.

Self-hosting? Use your instance's public HTTPS address instead of https://cloud.anythingmcp.com. Copilot Studio connects from Microsoft's cloud, so localhost does not work.

Available tools

ToolWhat it does
holded_list_contactsList contacts — customers, suppliers, leads — with their name, NIF/CIF, e-mail, address and the type flags that say which role they hold
holded_get_contactRead one contact in full: tax data, billing address, payment terms, default VAT rate and the notes recorded against them
holded_list_documentsList documents of one type — invoices, estimates, credit notes, purchase orders — with their number, date, contact, total and payment status
holded_get_documentRead one document in full: every line with its quantity, price, discount and VAT, the totals, and the payments applied against it
holded_list_productsList products and services with their SKU, name, price, cost, VAT rate and stock level

holded_list_treasury_accountsList the treasury accounts (bank and cash) with their name, IBAN and current balance — the cash-position answer
holded_list_funnelsList the CRM funnels with their stages, so a pipeline question knows which stages exist before asking about leads in them
holded_list_leadsList CRM leads with their name, contact, value, funnel stage and expected close date — the sales-pipeline view

FAQ

Which Copilot is this for? Microsoft 365 Copilot at work, through agents built in Copilot Studio. The Microsoft Copilot app for personal accounts has no option to add your own MCP server.

What do I need? A work account with access to Copilot Studio (a license or a trial) to build the agent. People who use it in Microsoft 365 Copilot or Teams need access to the agent: share it with them, or ask an admin to publish it to the organization. If your organization applies data policies to Power Platform connectors, they cover MCP servers too.

The agent doesn't call the tools. Check that the header name is exactly X-API-Key and that the key belongs to the same MCP server as the URL, and make the server description specific: Copilot Studio uses it to decide when to call the server. Publish the agent again after each change; in an open chat, type "start over" to get the new version.
