Implementation Reference

• src/requestrepo_mcp/server.py:224-232 (handler)

  The RequestrepoMCPService.update_dns method implements the core business logic for the update_dns tool. It validates confirmation, converts input records to DnsRecord models, calls the client to update DNS, and returns the updated records count and details.

  def update_dns(self, *, records: list[DnsRecordInput], confirm: bool) -> dict[str, Any]:
      self._require_confirm(confirm, "update_dns")
      dns_records = [DnsRecord(type=record.type, domain=record.domain, value=record.value) for record in records]
      updated = self._client().update_dns(dns_records)
      return {
          "updated": updated,
          "count": len(dns_records),
          "records": [serialize_dns_record(record) for record in dns_records],
      }

• src/requestrepo_mcp/server.py:441-444 (registration)

  The MCP tool registration for update_dns. This @mcp.tool() decorated function exposes the update_dns operation to the MCP server, accepting a list of DnsRecordInput and a confirm boolean parameter.

  @mcp.tool()
  def update_dns(records: list[DnsRecordInput], confirm: bool) -> dict[str, Any]:
      """Replace the full DNS records set."""
      return resolved_service.update_dns(records=records, confirm=confirm)

• src/requestrepo_mcp/schemas.py:10-18 (schema)

  Schema definitions for update_dns tool inputs. DnsRecordType defines allowed DNS record types (A, AAAA, CNAME, TXT) and DnsRecordInput is the Pydantic BaseModel used for each DNS record in the update_dns tool.

  DnsRecordType = Literal["A", "AAAA", "CNAME", "TXT"]
  
  
  class DnsRecordInput(BaseModel):
      """DNS record payload for update_dns."""
  
      type: DnsRecordType
      domain: str
      value: str

• src/requestrepo_mcp/serializers.py:40-45 (helper)

  Helper function serialize_dns_record that converts DnsRecord objects to dictionaries for API responses. Used by the update_dns handler to format output records.

  def serialize_dns_record(record: DnsRecord) -> dict[str, str]:
      return {
          "type": record.type,
          "domain": record.domain,
          "value": record.value,
      }
