Key Features
  • • Natural language querying of Amazon Bedrock Knowledge Bases
  • • Citation support for all retrieved results with source attribution
  • • Data source filtering and prioritization capabilities
  • • Repository Management: Browse and query code, search files across repositories, analyze commits, and understand project structure through MCP-accessible GitHub context. Access to private repositories depends on proper authentication and permissions.
  • • Issue & PR Automation: Create, update, and manage issues and pull requests programmatically where permissions allow. AI agents can use the MCP interface to gather context, assist triage, and support review workflows.
  • • CI/CD & Workflow Intelligence: Inspect GitHub Actions workflow runs and development pipeline status through available GitHub APIs and granted permissions. Workflow log and artifact access may depend on repository settings and token scope.
