The Tyms MCP server lets AI assistants work directly with your Tyms business through the Model Context Protocol (MCP). Once connected, your assistant can:
  • Look up accounts, contacts, invoices, bills, expenses, income, inventory, and more
  • Run financial reports (balance sheet, P&L, cash flow, trial balance, ledgers)
  • With the full endpoint: create, update, and delete records — including AI-assisted creation powered by Adam, Tyms’ AI agent
Tyms MCP is a hosted remote MCP server. You do not install a local package. Your client connects over HTTPS and authenticates with OAuth against your Tyms business.
MCP access is available in production. Use the production endpoints below.

​
Who this is for

Business owners & accountants

Connect Claude, ChatGPT, or Perplexity to ask questions about your books, pull reports, or (with care) bookkeep in plain language.

Teams using AI tools

Start on read-only, then enable write access only for trusted workflows that need to create or change records.

​
What you need

  1. A Tyms business you can sign into
  2. An MCP client that supports remote MCP and OAuth (Claude, ChatGPT, and Perplexity are supported with dedicated Client IDs)
  3. The correct MCP URL and the Client ID for your platform

​
Quick start

1

Pick an access level

Use read-only for lookups and reports, or /full only if you need the assistant to create, update, or delete data. See Endpoints.
2

Add Tyms in your MCP client

Follow the guide for Claude.ai, Claude Desktop, Claude Code, ChatGPT, or Perplexity.
3

Enter the Client ID if asked

Use the Client ID for your platform (Claude, ChatGPT, Perplexity, or the generic ID for other apps). See Authentication.
4

Approve access in Tyms

Sign in, choose the business, and finish OAuth. Then enable the Tyms connector in a chat and start asking questions.
