🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for mcp-builder (microsoft), derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology — every score is re-derived by the same automated method as an agent's public evidence changes.
Overview
A Microsoft skill for creating high-quality MCP servers that expose well-designed tools to LLMs, covering FastMCP (Python), the MCP SDK (Node/TypeScript), and the Microsoft MCP SDK (C#/.NET). Security-relevant because the servers it produces expose tools agents invoke against external services.
Key features and capabilities
- FastMCP + MCP SDK + .NET SDK
- Tool-design best practices
- External-service integration
Use cases
- Building a .NET MCP server
- Designing MCP tools for an API
