# Which AI assistants work with Biloh?

> Claude and Grok; ChatGPT with the core tool list. Biloh speaks the Model Context Protocol (MCP), the open standard these assistants use to call real tools, so you add Biloh as a connector in your own assistant, sign in, and allow the permissions you want — Read, Change, Send, Books. Assistant access is included in every plan. Every action the assistant takes also shows up in the app.

**Claude and Grok; ChatGPT with the core tool list.** You connect your own account with the assistant; Biloh does not resell one.

## Why does ChatGPT need the core tool list?

ChatGPT caps how many tools a connector may offer, and a business's full Biloh catalogue is over that cap. Turn on **Show connected assistants only the core tools** (the setting `mcp.tools_list.core_only`) in your business's settings and ChatGPT loads the core tool list: the everyday tools plus `search_tools`, which still finds and runs every other tool by name. Claude and Grok take the full list, so they need no change.

## How does the connection work?

Biloh runs an MCP server for every business. MCP (Model Context Protocol) is the open standard assistants use to call real tools in other software. You add Biloh as a connector in your assistant's settings with your business's address, sign in with your usual Biloh login, and choose the permissions it may use. The step-by-step is on [Connect your assistant](https://biloh.com.au/connect).

## What can each assistant do?

The same things, within the permissions you allow:

- **Read** — look things up: who owes what, what is on today, what came in.
- **Change** — create and edit records: a client, a job, a draft invoice. Nothing leaves.
- **Send** — approve an email, invoice, payment reminder or work order to go out; each one is staged first.
- **Books** — record payments and post to the ledger. Most owners keep this one for themselves.

Claude connects as a custom connector. Grok allow-lists tools by name, so Biloh publishes a core tool list to paste. ChatGPT connects as a custom connector once your business has the core tool list on (above).

## Does it cost extra?

No. Assistant access is included in every Biloh plan. You keep paying your assistant's provider whatever your own plan with them costs.

## Can I see what the assistant did?

Yes. Chat and the app are two views of the same records, so every job, quote, invoice and message the assistant touches is on a screen you can open, and anything the assistant writes to a client or contractor waits for your yes before it is sent.
