mcp-builder

Transform an OpenAPI 3.x spec and workflow descriptions into a validated mcp-scope.yaml that ultimately gets used to generate an MCP server. Guides the AI through spec analysis, semantic grouping, tool naming, description writing, and auth detection with interactive user gates. Use when a user wants to scope an API for MCP server generation.

Validate a generated MCP server project against the mcp-scope.yaml and OpenAPI spec that drove its generation, then suggest hint-driven improvements. Part of the mcp-builder pipeline that transforms an OpenAPI 3.x spec into a ToolHive-ready MCP server across four phases — AI Scoping, Human Review, Deterministic Code Generation, and AI Validation & Polish (this skill). Use when a user has a generated MCP server project (Phase 3 output) and wants to validate it before deployment.

Place generated MCP server deployment manifests into a cluster repo, fill in placeholders by inferring values from existing cluster configuration, and explain remaining manual steps. Use when you have a generated MCP server project and a cluster repo where you want to deploy it.
