What is the Cradl AI MCP Server?
Integrate Cradl AI, the advanced document data extraction platform, directly into your AI workflow. Automate the processing of invoices, receipts, IDs, and custom forms using powerful deep learning models and natural language.
What you can do
- Data Extraction — Trigger real-time data extraction from document URLs with high precision.
- Model Management — List and explore your custom-trained extraction models.
- Workflow Monitoring — Track the status of document processing flows and individual tasks.
- Batch Processing — Audit and retrieve details for entire batches of processed documents.
How it works
- Connect the Cradl AI integration to your AI assistant.
- Authorize using your Cradl AI API Key (found in your dashboard).
- Transform unstructured documents into actionable data via chat.
Who is this for?
- Finance Teams — Automate invoice and receipt processing without manual data entry.
- Operations Managers — Monitor high-volume document workflows and extraction accuracy.
- Developers — Audit model performance and task statuses during integration testing.
