Claude Code / Cursor / MCP Inspector (API token)

Create a free EZ@Work account at https://app.ezatwork.com
Generate an API token at https://app.ezatwork.com/settings/api-tokens
Connect to https://mcp.ezatwork.com/mcp with header Authorization: Bearer ezw_pat_...

Security

Your data stays in your EZ@Work account
OAuth mode: Google identity → EZ@Work account lookup; no credentials stored in the MCP
API token mode: scoped permissions — grant only what you need; mandatory expiration
Authorization is verified on every request

Universal Design

EZ@Work adapts to your business type: a lawyer sees "cases," a freelancer sees "projects," a service business sees "work orders." Currency, language (24 supported), and tax rules auto-detect from your profile — no configuration needed in the MCP.

Development

Run locally

bash

python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -e .

cp .env.example .env
# Edit .env: EZ_API_BASE=http://localhost:5000 for local backend

python -m ezatwork_mcp.server
# Server starts at http://localhost:8080/mcp

Run tests

Terminal

pip install pytest pytest-asyncio
pytest tests/

Docker

Terminal

docker build -t ezatwork-mcp .
docker run -p 8080:8080 -e EZ_API_BASE=https://api.ezatwork.com ezatwork-mcp

Deploy to Cloud Run

bash

gcloud run deploy ezatwork-mcp \
  --source . \
  --region europe-west1 \
  --project ezatwork-production \
  --allow-unauthenticated \
  --port 8080 \
  --update-env-vars "EZ_API_BASE=https://api.ezatwork.com,MCP_BASE_URL=https://mcp.ezatwork.com" \
  --update-secrets "GOOGLE_CLIENT_ID=ezmcp-google-client-id:latest" \
  --update-secrets "GOOGLE_CLIENT_SECRET=ezmcp-google-client-secret:latest" \
  --update-secrets "EZ_MCP_MASTER_TOKEN=ezmcp-master-token:latest"

--allow-unauthenticated is correct — auth is enforced at the MCP layer (OAuth or API token), not at the Cloud Run IAM level.

Transport: Streamable HTTP (/mcp endpoint)
Library: fastmcp 3.3.1
Auth (OAuth): GoogleProvider from fastmcp.server.auth.providers.google
