About Xero MCP
Xero MCP is an MCP server published by the GitHub account Servosity. Every Xero Accounting read plus a local SQLite ledger - aging, reconciliation, and GL tie-out
It runs on your own machine: your AI client starts it from the MCP bundle package xero-mcp.mcpb at version 0.1.9.
It asks for 4 secrets: XERO_ACCESS_TOKEN, XERO_CLIENT_ID, XERO_CLIENT_SECRET and XERO_OAUTH2. Give it a key with the least access that still works.
It also needs XERO_TENANT_ID set before it starts.
Version 0.1.9 was published on 23 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 1 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
XERO_ACCESS_TOKEN | Yes | Yes | Set the XERO_ACCESS_TOKEN credential for the Xero MCP server. |
XERO_AUTHORIZATION_URL | No | No | Authorization endpoint the login flow opens. Change it only if Xero moves the endpoint. |
XERO_BASE_URL | No | No | Base URL for the Xero API. Leave the prefilled default unless your account uses a different regional or self-hosted host. |
XERO_CLIENT_ID | No | Yes | Client ID of your Xero app (developer.xero.com > My Apps). Set it with the client secret to run the OAuth2 flow; leave blank if you paste an access token instead. |
XERO_CLIENT_SECRET | No | Yes | Client secret paired with XERO_CLIENT_ID. |
XERO_OAUTH2 | No | Yes | Optional. Sets XERO_OAUTH2 for the Xero MCP server. |
XERO_TENANT_ID | Yes | No | The Xero organisation ('tenant') GUID sent as the Xero-Tenant-Id header. Every call requires it; `connections list` returns the tenants your token can reach. |
XERO_TOKEN_URL | No | No | Token endpoint the client-credentials exchange posts to. Leave the prefilled default unless your tenant uses a different token endpoint. |
XERO_NO_CONFIG_WRITE | No | No | Set to 1 to keep credentials off disk. The token cache becomes a no-op, so the connector mints a fresh token each run instead of writing one to config.toml. Leave blank for the default cached behaviour. |
