Creating a Provider Resource

​
Using HasMCP UI

Create Provider Resource Modal To define a new data resource in the dashboard:
  1. Navigate to the specific Provider Details page.
  2. Select the Resources tab.
  3. Click the Add Resource button.
  4. Input the name (a unique URI-like string identifying the resource, e.g., https://api.example.com/logs/system.log), the mimeType (e.g., text/plain or application/json), and providing an optional description.
  5. Map the execution path the server will call to retrieve this data.
  6. Click Create to bind the resource to the provider catalog.

​
Using REST API

A Resource in MCP is typically used for injecting static files, database schemas, or distinct read-only data blobs into an agent’s context.

​
The API Endpoint

To programmatically declare a resource, you POST a ProviderResourceCreate object to the provider’s nested resources path. POST /providers/{providerId}/resources

​
JSON Payload Requirements

Your payload requires a resource object containing:
  • name (string): A short contextual name for the resource (e.g., Error Logs).
  • uri (string): The standard https:// REST URL where the resource data can be fetched (e.g., https://api.example.com/v1/system/logs/error).
  • mimeType (string): The standard MIME format of the data returned by this endpoint.
  • description (string, optional): A brief explanation of the data blob.
