Advanced Features

Request Cancellation

This MCP server supports request cancellation according to the MCP cancellation specification. Clients can cancel in-progress requests by sending a notifications/cancelled message with the request ID.

When a request is cancelled:

• The server immediately stops processing the request
• Any ongoing API calls are aborted
• Resources are cleaned up
• No response is sent for the cancelled request

Progress Notifications

The server supports progress notifications for long-running operations according to the MCP progress specification.

To receive progress updates:

1. Include a progressToken in your request metadata
2. The server will send notifications/progress messages with:
   • Current progress value
   • Total value (when known)
   • Human-readable status messages

Progress is reported for:

• Multi-step operations
• Batch processing
• Long-running API calls
• File uploads/downloads

Example progress notification:

{
  "method": "notifications/progress",
  "params": {
    "progressToken": "operation-123",
