Feature/mcp prompts

[mgreenberg-nni]

Summary

I've developed a unified prompt management system for LibreChat that seamlessly integrates with MCP server prompts, creating a powerful new feature ready for implementation.

Enhanced Workflow Efficiency
The integration provides direct access to your entire MCP prompt library within LibreChat's interface. This eliminates tedious copy/paste workflows between systems, allowing users to incorporate proven prompts into agent conversations without switching contexts or platforms. The experience becomes notably smoother and more productive for everyone.

Improved Collaboration
Team members can utilize approved prompts without requiring direct MCP server access, while maintaining a single source of truth since edits still happen exclusively on the MCP server. This controlled access model works perfectly for team members who need to use established prompts without requiring full system permissions, ensuring consistency while expanding usability across the organization.

Technical Excellence
Smart caching minimizes server load and maintains performance, with real-time synchronization ensuring prompts are always up-to-date when MCP updates occur. The system maintains complete security integrity by providing view-only access to prompts, preventing unauthorized modifications while making these valuable resources available throughout your entire workflow ecosystem.

Developer Experience
Agent creation becomes significantly streamlined through the ability to combine and reuse prompts from the established library. All formatting and special instructions from original prompts are preserved, eliminating duplicated effort and ensuring consistent quality across projects and team members.

Complete Implementation
The solution bridges the frontend layer with the existing and new backend architecture. Efficient state management integrates with the application, while the conversation flow incorporates elegant prompt selection capabilities directly in the message interface. The entire system has been thoroughly tested with various MCP server implementations to ensure broad compatibility.
