Harvest + ChatGPT
Manage Harvest (time tracking, projects, clients, invoices, expenses) from any AI agent. 10 tools, Bearer auth with account-ID header.
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:
HARVEST_ACCESS_TOKEN, HARVEST_ACCOUNT_ID
Step 1 — Get credentials
This connector wraps the Harvest API v2 (api.harvestapp.com/v2).
Setup:
- Log into https://id.getharvest.com → bottom-left avatar → Developers → Create new personal access token.
- Copy the token and the Account ID shown on the same page (a 7-digit number like
1234567). - Set both:
HARVEST_ACCESS_TOKENandHARVEST_ACCOUNT_ID.
Authentication: every request requires BOTH:
Authorization: Bearer ${HARVEST_ACCESS_TOKEN}Harvest-Account-Id: ${HARVEST_ACCOUNT_ID}- A
User-Agentheader (Harvest API requires it — the adapter setsAnythingMCP ([email protected])).
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(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:
Harvest. - 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.

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