Harvest + Claude

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:

  1. Log into https://id.getharvest.com → bottom-left avatar → Developers → Create new personal access token.
  2. Copy the token and the Account ID shown on the same page (a 7-digit number like 1234567).
  3. Set both: HARVEST_ACCESS_TOKEN and HARVEST_ACCOUNT_ID.

Authentication: every request requires BOTH:

  • Authorization: Bearer ${HARVEST_ACCESS_TOKEN}
  • Harvest-Account-Id: ${HARVEST_ACCOUNT_ID}
  • A User-Agent header (Harvest API requires it — the adapter sets AnythingMCP (support@anythingmcp.com)).

…(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 Claude

Recommended path — works on claude.ai web without editing any config file.

  1. Open claude.ai/customize/connectors.
  2. Click "Add custom connector".
  3. Fill in:
    • Name: Harvest
    • 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.
