How AI connector (MCP) works in WorkHoist

7 steps
  1. Connect it in three steps

    Settings, Bob: the Connect an AI assistant card with the three steps and the WorkHoist server address.

    In Claude or ChatGPT, add a custom connector named WorkHoist with your server address, sign in and approve. The approval starts with read access.

  2. Choose read access, or read and write

    Connect by signing in, or with an API key that reads, or reads and writes. Read and write lets the assistant create and update records across the jobs. Hand it a bid spreadsheet and it becomes the estimate, the phases and the budget, with the grand total checked against the sheet. From one sentence it drafts an invoice with retainage held, raises a change order, or adds a deal and books the site visit; deals, tasks, POs, RFIs, punch items, daily logs, time entries and Drive links too. It drafts; you send.

  3. Ask in plain English, answered from live figures

    Claude pulling a 90-day P&L across live WorkHoist projects and producing a report with charts.

    Ask for margin by project, who owes you, or which jobs are over budget, and the assistant reads the numbers from WorkHoist with the app’s own maths. Margin by project is what each job invoiced minus what it cost; the P&L lives in the app. AR aging comes in buckets from current to over 90 days.

  4. Receipts and statements into expenses

    A phone chat logging three receipts as expenses on a job, beside WorkHoist’s expenses list for that job.

    Photograph a receipt and say which job it was for; the assistant logs the expense. Hand it a vendor statement and every line becomes an expense on its job, with the card, the cost code and the reference, up to 200 lines at once. Each one waits for approval, as pending, and counts toward the job once somebody approves it.

  5. See every connected assistant

    Settings, Connected apps: Claude and ChatGPT connections with their access level, who connected them and Revoke buttons.

    Each connection shows who connected it, when, and whether it reads or reads and writes, with Revoke beside it.

  6. Bob, inside WorkHoist

    Bob answers questions about your jobs from your live data, with links to the records, without leaving the app.

  7. Usage you can see

    Settings, Bob: Bob switched on, the monthly usage bar with its cap and reset date, and the model setting.

    Bob runs on every plan with a monthly usage allowance, shown in Settings with when it resets.

You add WorkHoist as a connector in ChatGPT or Claude and sign in, the same way you would add any other connector. That is the whole setup.
With write access switched on, it can create 21 kinds of record and update 18, from logging an expense off a receipt to moving a task’s dates. You choose read access, or read and write, when you connect, and an expense it logs waits as pending until somebody in the office approves it, so a person signs off the money.
It sees your company’s data. The company is taken from the sign-in itself, so every connection is tied to your company, and a project manager’s connection reaches the projects they run.
Every plan. Every feature is switched on for every plan, with a monthly usage allowance for Bob; plans differ by how many paid seats you need and the onboarding you get.
