Release v5.3.0 into Main

[github-actions]

v5.3.0

Key Features

Model Context Protocol (MCP) Workbench

LISA now includes a comprehensive MCP Workbench that enables administrators to create, test, manage and host custom MCP tools directly within LISA.

MCP Tool Development

• Custom Tool Creation: Administrators can create and edit custom MCP tools using a built-in code editor with syntax highlighting
• Tool Testing Environment: Integrated testing capabilities for validating MCP tools before enterprise rollout
• Template-Based Development: Pre-built template and examples to accelerate tool development
• MCP file hosting support: Administrators can upload MCP tool code directly to S3. The MCP Workbench connection will automatically host this tool for use
• Improved Authentication: Enhanced authentication mechanisms for MCP server connections, if users specify {LISA_BEARER_TOKEN} in the header field, LISA will populate this with the users active token. This is important for proxying calls to internally hosted servers that use the same authentication mechanisms as LISA

Administrative Control

• Tool Management: Administrators can manage and configure the MCP workbench capabilities for their organization
• IDP Group Locking: MCP connections can now be locked down to specific Identity Provider (IdP) groups for enhanced security

Enhanced Model Control

• Custom API Key Support: Support for handling custom API keys for third-party models added to Model Management

Mermaid Diagram Sanitization

• Security Enhancement: Implemented sanitization for Mermaid diagrams to prevent potential security vulnerabilities
• Safe Rendering: Ensures that Mermaid diagrams are rendered safely without executing malicious code

What's Next?

We'll be launching broader MCP tool hosting capabilities in an upcoming LISA release.
