What your agent can do

Xero gives your agent 24 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

  • create_contact — Create a Xero contact (customer or supplier — Xero uses one unified Contact object with IsCustomer/IsSupplier flags inferred from transactions).
  • get_contact — Retrieve a single Xero contact by ContactID (UUID).
  • list_contacts — List Xero contacts. Supports Xero's where clause for server-side filtering (e.g. 'Name=="ACME Ltd"', 'IsCustomer==true').
Example call
// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("create_contact", { /* ... */ });

Install

terminal
$ npm install @codespar/mcp-xero

Quickstart

Add this entry to your claude_desktop_config.json (or any MCP-compatible client config).

claude_desktop_config.json
{
  "mcpServers": {
    "xero": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-xero"
      ],
      "env": {
        "XERO_ACCESS_TOKEN": "<your_xero_access_token>",
        "XERO_TENANT_ID": "<your_xero_tenant_id>"
      }
    }
  }
}

After restart, your agent can call any of the 24 tools below — try create_contact first.
