概要

What is MCP Spectral?

MCP Spectral is a Model Context Protocol (MCP) server that uses Spectral to lint OpenAPI specifications. It is designed for developers who want to validate and fix OpenAPI documents through large language model (LLM) tools such as Claude Desktop.

How to use MCP Spectral?

Install Docker and Claude Desktop, then add a Docker run command for marksivill/mcp-spectral to the claude_desktop_config.json file. Restart Claude Desktop to access three tools: lint_openapi, lint_openapi_with_ruleset, and spectral_version. Use natural language prompts to lint or build OpenAPI specs.

Key features of MCP Spectral

よくある質問

What tools does MCP Spectral offer?

It provides three tools: `lint_openapi`, `lint_openapi_with_ruleset`, and `spectral_version`.

What are the prerequisites to run MCP Spectral?

You need Docker installed on your machine and a host MCP client such as Claude Desktop.

How do I install and configure MCP Spectral?

Add a Docker run entry for `marksivill/mcp-spectral` to your `claude_desktop_config.json` file, then restart Claude Desktop. The Docker image will be pulled automatically.

Can MCP Spectral be used with other LLM tools besides Claude Desktop?
