Class: Resource

Defined in: packages/core/src/domain/Resource.ts:27

Represents an MCP Resource — a data source accessible via URI.

Resources are leaf nodes in the domain model hierarchy. They expose data that LLMs can read (e.g., files, database records, API responses).

Example

import { Resource, createAnnotations, Role } from '@vinkius-core/mcp-fusion';

const resource = new Resource('config');
resource.uri = 'file:///etc/app/config.json';
resource.mimeType = 'application/json';
resource.size = 1024;
resource.annotations = createAnnotations({
    audience: [Role.ASSISTANT],
    priority: 0.8,
});
