Spaceship MCP Server

MCP server for Spaceship (by Namecheap) — domain registrar with DNS management, WHOIS privacy, domain transfers, and a built-in SellerHub marketplace. Manage everything from any MCP-compatible client.

35 tools across 9 categories. Built-in response caching, rate limit handling with exponential backoff, and actionable error messages.

Claude Code

.mcp.json in your project root, or ~/.claude.json globally:

{
  "mcpServers": {
    "spaceship": {
      "command": "node",
      "args": ["/path/to/spaceship-mcp/dist/index.js"],
      "env": {
        "SPACESHIP_API_KEY": "your-api-key",
        "SPACESHIP_API_SECRET": "your-api-secret"
      }
    }
  }
}

Any MCP client (stdio)

The server uses stdio transport. Point your MCP client to:

node /path/to/spaceship-mcp/dist/index.js

With SPACESHIP_API_KEY and SPACESHIP_API_SECRET environment variables set.

Async Operations (1 tool)

| Tool | Description | |------|-------------| | ss_async_status | Check status of registration, renewal, transfer, or restore |

Async Operations

Domain registration, renewal, transfer, and restoration are asynchronous. These tools return an asyncOperationId — use ss_async_status to poll for completion. Statuses: pending, success, failed.

Response Caching

GET responses are cached for 120 seconds by default (configurable via SPACESHIP_CACHE_TTL). Write operations automatically invalidate related cache entries. Set SPACESHIP_CACHE_TTL=0 to disable caching entirely.

Rate Limit Handling

When Spaceship returns HTTP 429, the client automatically retries with exponential backoff, respecting the Retry-After header when present. Default: up to 3 retries. Timeout errors are also retried.

Security

30-second timeout on all HTTP requests
Path injection prevention (rejects .., #)
Automatic retry with backoff for rate limits and timeouts
Error responses truncated to 500 characters
Context-aware recovery hints in error messages
JSON parsing wrapped in try/catch
All parameters validated with Zod schemas
No credentials stored on disk (env vars only)
