What we tested and what we didn't

Tested on 2026-10-24

  • We attempted an MCP initialize to the vendor's hosted endpoint with no credentials and got HTTP 401, so we never reached the tool list (Method details: initialize POST answered 401; tools/list not sent)
  • Auth response: HTTP 401, WWW-Authenticate resource_metadata https://api.xero.com/.well-known/oauth-protected-resource/mcp/v1, OAuth metadata lists authorization server https://identity.xero.com. Login is an OAuth sign-in; we did not sign in
  • Vendor docs: official MCP docs page; states the endpoint URL (10/15)
  • Maintenance: dated vendor source, vendor release note 2026-10-13 (25/25)
  • License: a hosted service has no license to cite (0/10)

Not tested

  • Security: not audited (hosted service; no code to review, no permission or data-flow analysis)
  • Behaviour after signing in, or with a real account
  • Source code, repository activity or an open-source license (none published for the hosted service)
  • Performance, rate limits or load
  • Real tasks (no functional task runs yet)

Methodology: how we test (vendor-hosted rule). A high score means it responds and its vendor documents and dates it, not that it is safe to give it access to your data.

Known security issues

Not checked (remote-only): hosted endpoint, version unknown.

Tool list changes

No tool list: this server did not list tools without credentials in our test, so tool changes are not tracked.

Setup

Without credentials it said (verbatim): Needs credentials: vendor-hosted, OAuth sign-in required. HTTP 401 with OAuth challenge (WWW-Authenticate resource_metadata https://api.xero.com/.well-known/oauth-protected-resource/mcp/v1; metadata lists authorization server https://identity.xero.com). We do not sign in; not counted as working until a credentialed test exists.

  1. Install. No install step: it is a remote server at https://api.xero.com/mcp/v1.
  2. Configure. Add the mcpServers entry below to your MCP client config.
  3. Verify. Restart the client and check that tools/list returns tools. In our test it did not list tools without credentials.
