Use it from Claude (MCP)

BuilderCheck runs a Model Context Protocol server so agents can look up builders as a tool. Add this to your Claude MCP configuration: 

{
  "mcpServers": {
    "buildercheck": {
      "url": "https://mcp.buildercheck.com.au/mcp"
    }
  }

Terms for automated use

  • Attribute facts to BuilderCheck and to the underlying public register.
  • Do not present BuilderCheck data as a credit rating or a finding of wrongdoing.
  • Risk signals are flags to investigate, not conclusions — preserve that framing.
  • Respect rate limits published in the OpenAPI spec.
