| Handshake time | 4,375 ms over 1 attempt |
The endpoint answered the handshake with a sign-in challenge, so the tool list is not visible to this directory. It is not counted as an MCP server: a sign-in challenge is its own state, and the connector listed no tools.

The sign-in route, step by step
- Request
https://mcp.taxapp.nz/mcpwithout a token. It answers 401 and aWWW-Authenticateheader. - Read the protected resource metadata at
https://mcp.taxapp.nz/.well-known/oauth-protected-resource/mcpto find the authorization server. - Register a client at the registration endpoint
https://api.taxapp.nz/api/oauth/register(dynamic client registration), so no human has to create an app first. - Send a person through the authorization page, then retry the endpoint with the bearer token. The connector stops after step 2 and never authorizes.
See OAuth for MCP: client ID metadata documents and dynamic registration for how each route works.
CLI
No CLI is on record for Taxapp. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See shipping a CLI agents can use.
