What is the OpenAPI Schema Explorer?

It's an MCP server that provides token-efficient access to OpenAPI/Swagger specifications as MCP Resources, ideal for exploring API structures in LLM contexts.

What versions of OpenAPI/Swagger are supported?

The Explorer supports OpenAPI v3.0 and Swagger v2.0. Swagger v2.0 specifications are automatically converted to OpenAPI v3.0 upon loading.

How do I load an API specification?

You can load specifications from local file paths or remote HTTP/HTTPS URLs. Simply provide the path/URL when configuring the server in your MCP client.

What are MCP Resources, and why use them?

MCP Resources represent data sources for read-only access, perfect for browsing API paths and components within MCP clients like Claude Desktop. They minimize token usage for LLMs.

What output formats are available?

You can retrieve the specification data in JSON (default), YAML, or minified JSON formats by using the `--output-format` argument.
