GitHub: sanctum‑letta‑mcp · internal MCP orchestration layer for Letta (GitHub)

What’s New

We’re excited to roll out the first major release of the Sanctum MCP Server for Letta—a core orchestration layer that integrates deeply with the Letta agent framework. This release unlocks scalable, persistent agent deployments and enables advanced memory and tool management.

Highlights:

• Implements full Model Context Protocol (MCP) support for Letta agents, including tools, prompt integration, and rich metadata schemas (GitHub)
• Agent & Memory Management: Create, clone, modify agents; manage memory blocks and passages with structured schemas and behavioral annotations (GitHub)
• Tool Integration: Upload, attach, list tools; attach custom Python tools with metadata directly to agents (GitHub)
• Multiple transport protocols: Supports HTTP (streaming), SSE (Server-Sent Events), and standard I/O—for flexible integration and compatibility (GitHub)

Why It Matters

This MCP server brings real project momentum:

• ✅ Enables central orchestration for Letta-based AI agents—supporting multi-session, multi-user environments with proper flow control
• ⚙️ Offers plugin-style configurability: nearly every component is customizable via MCP interfaces
• 🧱 Lays the foundation for future plugins and extensions: custom prompts, memory optimizers, debugging assistants, etc. (GitHub)

Community & Collaboration

Sanctum is evolving collaboratively, and we welcome community involvement. You can help by:

• Testing and reporting edge cases or bugs in integrations (e.g. issues around tool loading or agent behavior)
• Proposing new MCP prompts or tools suitable for Letta workflows
• Submitting contributions or pull requests via GitHub—our open-source process is live now ([X (formerly Twitter)][2], GitHub)

What’s Next

Over the coming weeks, we plan to:

• Expand toolset support with new workflows: memory summarization, migration utilities, cleanup tools, etc.
• Improve integration with agent frameworks like Claude Desktop, and refine daemon/transport support across platforms
• Formalize threading and context-reset capabilities via MCP triggers, optimizing for persistent, multi-user scenarios (like([@myGirlMonday][http://t.me/myGirlMonday]) ).
