MCP Builder
Goal
Create clear, maintainable MCP server implementations with safe tool contracts.
Workflow
- Capture requirements: tools, resources, prompts, auth model, and target runtime.
- Design strict input/output schemas and error contracts.
- Scaffold project structure and server entrypoints.
- Implement handlers with validation, observability, and graceful errors.
- Add local test and smoke-check paths.
- Document setup, transport configuration, and security expectations.
Design Rules
- Keep tools focused and composable.
- Validate all inbound params before execution.
- Return actionable errors with stable shapes.
- Avoid leaking secrets in logs or responses.
Done Criteria
- Server starts and responds to at least one real tool/resource call.
- Schemas and usage are documented.
- Safety and auth assumptions are explicit.
