What does the mcp-add-tool skill actually do?

It provides a step-by-step walkthrough to help you define, code, register, and test a new tool within an existing MCP server environment.

What testing frameworks does it support?

The skill is pre-configured to generate unit tests using Vitest, covering successful executions, validation failures, and edge cases.

How does it improve tool security?

It enforces strict Zod schema constraints, such as maximum string lengths and value ranges, and runs a security audit to prevent SQL injection and credential leaks.

Does this skill help with documentation?

Yes, it searches your project's local documentation and OpenAPI specs to ensure the tool uses the correct domain terminology and usage patterns.

API Development

Streamlines the creation of enterprise-grade MCP server tools with automated schema validation, security audits, and test generation.

The mcp-add-tool skill provides a comprehensive, guided workflow for expanding Model Context Protocol (MCP) servers. It assists developers in designing robust Zod-based input schemas, researching existing project documentation for domain context, and generating boilerplate code for tool handlers and registration. By enforcing a mandatory security review and automatically creating Vitest suites, it ensures that every new capability is secure, well-documented, and production-ready for AI consumption.
