FAQ from @openapi-mcp/server

What OpenAPI versions and authentication methods are supported?

OpenAPI v3.0.0 and v3.1.0 are supported. Authentication includes HTTP Basic, static Bearer tokens, and header-based API keys. OpenAPI v2.0 (Swagger), OAuth 2.0, OpenID Connect, query param API keys, cookie auth, and dynamic JWT are not supported.

Is an operationId required for every operation?

Yes, every operation in your specification must have a unique operationId. The server will fail to start or process the specification if any operation is missing this field.

What are the runtime dependencies for @openapi-mcp/server?

The server requires Bun as the JavaScript runtime. Dependencies are installed via bun install. The server runs as a CLI process via MCP’s stdio transport.

How do I configure the server for use with Claude Desktop?

Add the server to your Claude Desktop configuration, specifying the bun command and path to the server script, along with the required BASE_URL environment variable and optional HEADERS for authentication.
