# FAQ

> Common questions about Tyms MCP, Client ID, endpoints, and supported clients.

## What Client ID should I use?

It depends on the platform:

| Platform                          | Client ID                |
| --------------------------------- | ------------------------ |
| Claude (Claude.ai, Desktop, Code) | `usetyms-mcp-claude`     |
| ChatGPT                           | `usetyms-mcp-chatgpt`    |
| Perplexity                        | `usetyms-mcp-perplexity` |
| Any other MCP client              | `usetyms-mcp-client`     |

Enter the matching ID whenever the platform asks for a Client ID after you provide the MCP URL. See [Authentication](/mcp/authentication).

## Can I use sandbox?

This documentation covers **production** MCP: `https://mcp.usetyms.com` and `https://mcp.usetyms.com/full`.

## What’s the difference between Tyms and Adam?

**Tyms** is the accounting platform. **Adam** is Tyms’ AI agent used on AI create tools (for example: “create invoice from a description”). Manual create/update tools talk to the Tyms API directly.

## Why do I only see list/get tools?

You’re connected to the read-only endpoint (`/mcp`). Switch the connector URL to `/full` for write tools. See [Read-only vs full](/mcp/read-vs-full).

## Does MCP replace the Tyms API?

No. MCP is an assistant-friendly layer over Tyms business operations. Developers building custom apps should still use the [Tyms Developer API](/introduction).

## Which clients are officially supported today?

**Claude**, **ChatGPT**, and **Perplexity** each have a dedicated Client ID. Other MCP clients may work with `usetyms-mcp-client` if they support remote Streamable HTTP + OAuth. See [Other clients](/mcp/clients/other).

## Do I need to install a package?

No. Tyms MCP is a **hosted remote** server. You connect over HTTPS with OAuth — there is no local MCP package to install.
