agentic-mcp-server-builder
Scaffold MCP server projects and baseline tool contract checks. Use for defining tool schemas, generating starter server layouts, and validating MCP-ready structure.
About this skill
The 'agentic-mcp-server-builder' skill is designed to automate the initial setup of an MCP server project. It takes a server name and a list of tools with descriptions as input, then generates a basic file map for the server scaffold and a summary of the tool contracts. This process ensures a consistent and standardized starting point for developing modular AI agent services. This skill is crucial for enforcing architectural best practices and accelerating development. By automatically creating the foundational directory structure and defining clear input/output schemas for tools, it allows developers to quickly move from concept to implementation without getting bogged down in boilerplate code or manual setup. The contract checks provide an early validation of tool interoperability. Users leverage this skill to kickstart new agentic services, establish clear interfaces for various capabilities, and ensure their modular components adhere to a defined structure from day one. It streamlines the initial phase of AI agent development, promoting scalability and maintainability across projects.
Best use case
This skill is primarily for developers and teams building new modular AI agent servers or services that conform to the MCP (Modular Capability Platform) standard. It's ideal for quickly prototyping new agent capabilities or establishing a robust, consistent foundation for production-grade agentic systems, ensuring that tool definitions and server layouts are standardized from inception.
Scaffold MCP server projects and baseline tool contract checks. Use for defining tool schemas, generating starter server layouts, and validating MCP-ready structure.
A new directory containing a basic MCP server scaffold with starter files and a summary of defined tool contracts, ready for business logic implementation.
Practical example
Example input
Create an MCP server named 'my-smart-agent' with tools: 'weather_fetcher' (description: 'Fetches current weather data for a location'), 'news_summarizer' (description: 'Summarizes top news articles').
Example output
Successfully generated 'my-smart-agent' MCP server scaffold. File map created. Tool contract summary: - weather_fetcher: input (location: string), output (temperature: float, condition: string) - news_summarizer: input (topic: string, count: int), output (summaries: list[string]) Starter files materialized in './my-smart-agent/'.
When to use this skill
- When starting a new MCP server project from scratch.
- To define and validate tool schemas and contracts for agentic services.
- For generating consistent starter file layouts across multiple projects.
- When automating boilerplate creation for modular AI capabilities.
When not to use this skill
- For general coding tasks unrelated to MCP server scaffolding.
- When modifying an existing, already established MCP server.
- If you are not developing within a modular capability platform context.
- For deploying or managing operational AI agent servers.

# Agentic MCP Server Builder ## Overview Create a minimal MCP server scaffold and contract summary from a structured tool list. ## Workflow 1. Define server name and tool list with descriptions. 2. Generate scaffold file map and tool contract summary. 3. Optionally materialize starter files when not in dry-run mode. 4. Review generated contract checks before adding business logic. ## Use Bundled Resources - Run `scripts/scaffold_mcp_server.py` to generate starter artifacts. - Read `references/mcp-scaffold-guide.md` for file layout and contract checks. ## Guardrails - Keep tool boundaries explicit and minimal. - Include deterministic outputs and clear input/output schemas.
