This release introduces comprehensive support for MCP prompts, enabling MCPProxy to aggregate and securely manage prompts from upstream MCP servers with the same intelligent filtering and security controls available for tools.
New Features
- Prompt Aggregation: MCPProxy now aggregates prompts from upstream MCP servers through
prompts/list, making them available to connected AI clients - Per-Prompt Rug-Pull Protection: Implemented baseline rug-pull approval workflow for prompts (Spec 100), providing the same security quarantine capabilities that tools have. Users can review and approve prompts before they're exposed to AI clients
- Dynamic Prompt Updates: Automatically reacts to
prompts/list_changednotifications (F13) from upstream servers, keeping the prompt catalog synchronized in real-time - In-App Project Links: Added convenient links within the application back to the MCPProxy project for easy access to documentation and community resources
Improvements
- Prompt Security Hardening: Enhanced security controls for upstream prompt aggregation including validation, sanitization, and access controls (F2/F10/F12)
- Prompt Workflow Polish: Refined the prompt aggregation workflow with improvements to listing, filtering, approval operations, and tool argument handling (F6/F7, F9, F14, F15)
Bug Fixes
- Documentation Site: Fixed scrollable tables that were experiencing layout overflow issues under the right table of contents. Also improved cell code wrapping for better readability
Note: Prompt aggregation features are available in both Personal and Teams editions. The rug-pull approval workflow operates per-user in Personal edition and can be configured per-team in Teams edition.
