Claude Code - Tyms Developer API

Claude Code can connect to Tyms MCP over HTTP. Other MCP-compatible CLI clients that support remote MCP + OAuth can use the same URLs; labels in the UI may differ.

Add the server

# Read-only
claude mcp add --transport http tyms https://mcp.tyms.io

# Read + write
claude mcp add --transport http tyms-full https://mcp.tyms.io/full

Complete OAuth

In a Claude Code session, run /mcp.
Follow the prompts to connect and authorize.
If the client asks for a Client ID, enter:

usetyms-mcp-claude

Sign in to Tyms and approve the business.

Which URL should I use?

Goal	Command / URL
Lookups and reports only	`https://mcp.tyms.io`
Create, update, delete, post payments	`https://mcp.tyms.io/full`

/full can change real business data. Prefer read-only unless you need write tools, and keep confirmation / approval on for destructive actions.

After connecting

Ask accounting questions in natural language, for example:

List unpaid invoices over 30 days and group them by customer.

See Example prompts and Capabilities.
