Wave Accounting + ChatGPT
Query Wave Accounting (businesses, customers, products, invoices, chart of accounts) and create customers or email invoices via Wave's GraphQL API from any AI agent. 8 tools, Bearer token 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:
WAVE_ACCESS_TOKEN, WAVE_BUSINESS_ID
Step 1 — Get credentials
This connector wraps the Wave GraphQL API (gql.waveapps.com/graphql/public).
Setup:
- Sign in to https://my.waveapps.com → bottom-left avatar → Manage Applications → Create Application.
- Use the OAuth flow to obtain an access token, OR (faster) generate a Full Access Token from the application settings (single-tenant).
- Business ID: Wave is multi-business — call
wave_get_businessesand take theidof the business to work in. - Set
WAVE_ACCESS_TOKENandWAVE_BUSINESS_ID.
Authentication: Authorization: Bearer ${WAVE_ACCESS_TOKEN}.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
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.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Wave Accounting. - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
