Dispatch forwarded the server&#39;s own stored credentials, the Telnyx API key and client secret together with the code-execution key, to the upstream endpoint, so an unauthenticated caller able to reach the port acted with them. The current code defaults the host to loopback, requires a server API key, and enforces it in middleware.</p> <p><strong>Affected:</strong> team-telnyx telnyx-mcp</p> <p>The Telnyx MCP server exposed its HTTP transport on every interface and did not require a caller credential. packages/mcp-server/src/http.ts served MCP on the root path with a listener bound to all interfaces and parsed the caller&#39;s authentication headers in a mode that did not fail when they were absent, so a request without any credential completed initialisation and dispatched tools.
