When to use
- You want to expose an external API, internal tool, database, or workflow to an AI client through MCP.
- You need help deciding which tools to expose, what schemas they accept, and how to keep the interface small and safe.
- You have a prototype MCP server and want to add validation, error handling, tests, authentication boundaries, and operational notes.
- You want a structured build path without pretending that generated code is automatically production-ready.
Do not use it to skip vendor docs, bypass authentication rules, expose secrets, or ship untested tools. The skill may help produce production-aware code, but it should call a server "production-ready" only after tests, security review, realistic error handling, and deployment/runbook evidence are present.
What it does
Guides an MCP build through:
- Scope design: defines the user jobs, the minimum tool set, naming, schemas, pagination, and read/write boundaries.
- Implementation plan: suggests TypeScript or Python structure, MCP SDK usage, typed inputs, environment configuration, and clear file layout.
- Safety review: checks auth model, secret handling, least privilege, input validation, rate limits, retries, idempotency, and dangerous write operations.
- Test plan: covers happy path, invalid arguments, empty responses, API errors, pagination, auth failure, rate limits, and destructive-action confirmation.
- Operational readiness: documents install steps, env vars, logging, versioning, rollback, and known limitations.
It lowers or qualifies claims when evidence is missing. "Production-grade" requires proof: passing tests, audited auth/permissions, documented failure modes, and a deployment path the user can run.
How to use
- Describe the API or tool you want to expose, the AI client, preferred language, and whether tools are read-only or can write data.
- Provide API docs, auth requirements, sample requests/responses, rate limits, and any compliance or data-sensitivity constraints.
- Ask for a design before code: tools, schemas, boundaries, risk list, and test plan.
- Generate the server incrementally. After each tool, run the suggested tests and fix failures before adding more tools.
- Before shipping, ask for a readiness review: security, permissions, tests, logs, docs, install steps, and caveats.
Best for
Developers and technical teams building internal or niche MCP servers where correctness and safety matter. Best when API docs and sample data are available; weaker when the external API is undocumented, credentials are missing, or the user wants broad write access without a review process.
