Tier: POWERFUL · Category: Engineering · Domain: AI / API Integration Use this skill to design and ship production-ready MCP servers from API contracts instead of hand-written one-off tool wrappers. It focuses on fast scaffolding, schema quality, validation, and safe evolution. The workflow supports both Python and TypeScript MCP implementations and treats OpenAPI as the source of truth. Convert OpenAPI paths/operations into MCP tool definitions Generate starter server scaffolds (Python or TypeScript) Enforce naming, descriptions, and schema consistency Validate MCP tool manifests for common production failures Apply versioning and backward-compatibility checks Separate transport/runtime decisions from tool contract design You need to expose an internal/external REST API to an LLM agent You are replacing brittle browser automation with typed tools You want one MCP server shared across teams and assistants You need repeatable quality checks before publishing MCP tools You want to bootstrap an MCP server from existing OpenAPI specs 1. Start from a valid OpenAPI spec. 2. Generate tool manifest + starter server code. 3. Review naming and auth strategy. 4. Add endpoint-specific runtime
