Basic example for https://petstore3.swagger.io/ 🎉 More complex example, using Github's API: This example use the bearer token auth (with a Github Personal Access Token) and force the tool naming strategy to \"verb and path\", as Github's operation ids are not valid tool names. Install As a Nuget tool: openapi-to-mcp Or download the executables from the releases Usage OpenAPI support - Currently, OpenAPI 2.0 and 3.0 are supported. - 3.1 is not (at least not until microsoft/OpenAPI.NET supports it) - Specifications can be JSON/YAML and local (file) or remote (URL) - Only local $refs are supported OpenAPI custom extensions A set of custom extensions is available to customize how your API should be exposed: - info.x-mcp-instructions (string): Textual instructions exposed by the MCP server during the initialize handshake - operation.x-mcp-tool-name (string): Custom tool name - operation.x-mcp-tool-description (string): Custom tool description - operation.x-mcp-tool-enabled (boolean): Enabled/disabled a specific operation (enabled by default) MCP features Only STDIO transport is currently supported.
