Oct 1, 2025October 2025 (2025-10) monthly summary: Delivered high-impact MCP improvements in Teleport, focused on reliability, observability, and user-facing tooling. Core MCP transport enhancements introduced streamable HTTP with JWT-backed security and SSE header rewrite, enabling robust interaction for tsh connect and UI protocol handling. Added server-level observability via Prometheus metrics to improve visibility into session activity, message flow, and transport errors across different transport types. Fixed a container cleanup race condition to ensure MCP-created containers are reliably removed, with an accompanying targeted reproduce test to prevent regressions. Introduced an MCPServerDialer abstraction to encapsulate server discovery and connection logic, improving code organization and testability. Expanded CLI resource management in tctl/tsh to cover databases, apps, app_servers, and Git servers, including new commands such as tsh proxy mcp and removal of MFA requirements for databases. These changes reduce operator toil, improve deployment reliability, and accelerate troubleshooting and onboarding for MCP-enabled workflows.

May 1, 2025May 2025 performance-focused month for gravitational/teleport: Security, access, and reliability improvements across the Teleport stack. Key features include reusable MFA sessions for database certificate generation to streamline tsh db exec, GitHub proxy access with cross-session identity persistence, and MCP framework integration across server access, app definitions, host user configurations, roles/permissions, auditing, and Claude Desktop tooling. Addressed legacy protocol by removing ALPN-based upgrade path in favor of WebSocket upgrades, improved AWS OpenSearch domain discovery via batching, and fixed EnumerateEntities role-based filtering, plus tightening of signed request authentication for ElastiCache/MemoryDB. These changes reduce MFA prompts, improve cross-service consistency, increase security, and enhance reliability for large-scale deployments, delivering measurable business value in reduced friction, improved security posture, and better governance telemetry.
