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:

INVOICED_API_KEY

Step 1 — Get credentials

This connector wraps the Invoiced REST API (api.invoiced.com).

Setup:

  1. Log into https://app.invoiced.comDevelopers → API Keys → Create API Key.
  2. Set INVOICED_API_KEY.
  3. Sandbox: for testing, point baseUrl at https://api.sandbox.invoiced.com instead.

Authentication: HTTP Basic — API key as username, empty password.

Hierarchy: Customer → Invoice → Line items → Payments. Subscriptions generate recurring invoices automatically.

Pagination: cursor-based via Link headers. Use per_page (max 100) and page (1-based).

Rate limits: 60 req/min per API key, 1k/hr. 429 with Retry-After.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && 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: Invoiced
    • 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.
