Quipu + ChatGPT

Quipu — Spanish invoicing and bookkeeping for autónomos and small companies: issued and received invoices, contacts, items, expenses and bank accounts. REST API, OAuth 2.0 client credentials.

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:

QUIPU_CLIENT_ID, QUIPU_CLIENT_SECRET

Step 1 — Get credentials

Getting credentials

  1. Sign in to Quipu and open the developer area (developers.getquipu.com) to register an application against your account.
  2. You receive a client id (app_id) and client secret. Quipu's API uses the client-credentials grant, so there is no browser consent step for your own account's data.
  3. Set QUIPU_CLIENT_ID and QUIPU_CLIENT_SECRET. AnythingMCP fetches and refreshes the access token on its own.

…(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 ChatGPT

ChatGPT supports MCP servers via the Connectors feature (Plus / Pro / Team / Enterprise plans). The free tier does not support custom connectors.

  1. Open ChatGPT → Settings → Connectors (or click the 🔧 icon in the composer → Manage connectors).
  2. Click "Add custom connector".
  3. Fill in:
    • Name: Quipu
    • MCP server URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
  4. Click Connect to authorize.
