get_v1_projects_slug_domains

ListDomains returns every custom hostname this site holds: the live ones, plus any pending claim with the DNS records it still owes.

domains is the routing answer — the hosts that are verified right now — while claims is the full panel, one row per host, each saying whether it is live or pending and, if pending, exactly what to publish.

Scope: a validated principal is required (403 without one) and the site is resolved within that principal's org, so another tenant's slug is a 404.

Arguments

tools/list declares a type and a description for each field and nothing further. The Required column is taken from GET /v1/projects/{slug}/domains, the operation this tool dispatches to — the same declaration the REST API validates against. A — means neither the door nor that operation constrains the field.

Call it

A tools/call carries every argument in one flat object — nothing binds to a path or a query string. This call carries exactly the arguments the operation requires, so it is the smallest one that can run.

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "get_v1_projects_slug_domains",
         "arguments": {
           "slug": "<slug>"
         }
       }
     }'

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.

The operation behind it

The same capability over plain HTTP is in the projects API reference, on https://api.hanzo.ai.
